Choose an Inkjet Printer Designed to Produce High-Quality Images
1Purchase a printer capable of printing high resolution photos and graphics. Not all devices are made equally in terms of print quality, and a printer's performance is most often reflected in its price. Review the device specifications prior to purchasing an inkjet printer.

Choose a printer model that provides 48-bit color support and an optical scan resolution of at least 2,400 dots-per-inch (dpi) for the best results.
Read and compare the product reviews for several different devices to help determine which inkjet printer will produce the best quality images and photos.
2Consider purchasing a photo printer. Photo printers are designed specifically for printing photographs, and usually produce the highest quality results. A dedicated photo printer typically will produce better quality images than a multipurpose printer.
Use High Resolution Images for Optimum Results
1Start with the highest quality original image files when printing photos from an inkjet printer. For best results, the original image files should range between 2,400 and 4,800 dpi.
Right click on an image file and select "properties" from the pull-down menu to determine the resolution quality of an original image file.
2Adjust the resolution settings on the digital camera used to take the original images to the maximum available dpi setting for best results.
Follow the Manufacturer's Recommended Maintenance Schedule and Best Care Practices
1Use the highest quality photo-grade paper recommended by the manufacturer. All inkjet printers are specifically calibrated for use with certain types of paper media. Using products other than those recommended by the manufacturer will often lead to color saturation issues that can negatively impact the quality of photos and images.
2Follow the inkjet printer maintenance and care instructions as directed by the manufacturer. Directions for performing scheduled maintenance can be found in the user's manual included with the printer at the time of purchase. Tasks, such as head cleaning and printer alignment, typically can be implemented from the device's control panel.
Adhere to the recommended maintenance on an inkjet printer, as directed by the manufacturer. Blocked nozzles and clogged printer heads are a common source of issues with inkjet printers and can compromise print quality.
Turn off the device when not in use. Leaving the device turned on exposes the printer heads to dust particles and debris, which can degrade the quality of images printed from an inkjet printer.
Confirm that the latest device drivers and firmware updates are installed on the printer. These updates usually can be downloaded free of charge from the printer manufacturer's website.
Save high-quality photo ink cartridges for use only when printing images and graphics to reduce wear and tear on the print heads. Ink cartridges tend to be fragile and can damage easily.
Adjust the Printer and Application Settings for Optimum Print Quality
1Adjust the print speed on the device to the highest available quality setting. The print speed control setting usually is found in the printer's control panel, located on top or in front of the device.
Decrease the print speed when image colors are faded. Increase the print speed on the device when images bleed or are oversaturated.
2Adjust the resolution settings on the printer to the highest possible dpi. The dpi setting usually can be adjusted from the device's control panel.
3Adjust the print settings in the software application being used to process and print the photographs or images to the highest possible quality or image resolution settings. These settings typically can be accessed from the "Print" dialog box or the "Preferences" option located in the file menu of the application being used.

Celebrating Pride 2012
We encourage people to bring their whole selves to work. And this month Googlers, Gayglers (gay Googlers), and their families and friends took this spirit to the streets in Pride parades and celebrations around the globe. In Sao Paulo, a group of 50 marched as a Google contingent for the first time ever. In San Francisco, more than 1,000 Googlers and allies marched (nearly doubling the number of people we had in 2011!). In New York, more than 700 of our friends and colleagues took over 5th Avenue marching alongside our double-decker Pride bus. And this weekend in Singapore, we’re sponsoring the Pink Dot celebration for the second consecutive year.
It’s not just through Pride that we show our support for the LGBT community. At Mardi Gras in Sydney, we hosted two Queer Thinking seminars on Activism in the Internet Age and Queer Careers. We also have big plans for the World Pride celebration in London this year, launching a “Legalise Love” Conference at Google London, partnering with organizations to identify ways to decriminalize homosexuality and eliminate homophobia around the world.
In addition to supporting the LGBT community outside of Google, we made some changes to our benefits offerings to support our Gayglers. Earlier this year, we enhanced our transgender-inclusive benefits to cover transitioning procedures and treatment in accordance with the World Professional Association for Transgender Health’s (WPATH) Standards of Care, which includes coverage for procedures like facial feminization for transgender women and pectoral implants for transgender men. We also increased our lifetime maximum coverage for these benefits to $75K—more than double what it had been previously.
Next month we’ll carry the energy of Pride into our fourth annual company Diversity & Inclusion celebration, the Sum of Google. The Sum is an opportunity to celebrate and engage in a discussion about diversity and inclusion across our offices around the world.
Take a look at the photos below for a peek at this year's Pride celebrations.

Chrome & Apps @ Google I/O: Your web, everywhere
This morning we kicked off day 2 at I/O to talk about the open web—one of the most amazing platforms we have seen. To put things in perspective, today there are more than 2.3 billion users on the web—a staggering number, but it only represents one-third of the world’s population. There’s still a lot of opportunity for growth.
Chrome, which we built from the ground up as a browser for the modern web, has seen tremendous adoption. Thanks to many of you, Chrome has nearly doubled since last year’s I/O—from 160 million to 310 million active users around the world. As more and more of you live your lives online, we want to to help make it easy for you to live in the cloud...seamlessly.
A better web to your web
One of the most exciting shifts is the explosion of the mobile web. When Chrome first launched, many people were tethered to a single computer. Today most people use multiple computers, smartphones and tablets. With that trend in mind, our goal is to offer you a consistent, personalized web experience across all devices. In February, we released Chrome for Android, which exited beta this week and is the standard browser on Nexus 7, a powerful new tablet.
Starting today, Chrome is also available for your iPhone and iPad. That means you can enjoy the same speedy and simple Chrome experience across your devices. Also, by signing in to Chrome, you can easily move from your desktop, laptop, smartphone and tablet and have all of your stuff with you.
Living in the cloud
A modern browser is just one ingredient of living online seamlessly. We continue to invest in building cloud apps, which many people rely on daily. Gmail, which launched in 2004, has evolved from a simple email service to the primary mode of communication for more than 425 million active users globally. We’ve also built a suite of apps to help users live in the cloud, including Google Documents, Spreadsheets, Calendar and more.
At the hub of this cloud experience is Google Drive—a place where you can create, share, collaborate and keep all your stuff. Ten weeks ago we launched Drive and in 10 weeks, more than 10 million users have signed up. Today we introduced more capabilities, including offline editing for Google documents and a Drive app for your iPhone and iPad. Drive is also seamlessly integrated into Chrome OS. With Drive available across Mac, Windows, Chrome OS, Android and iOS, it’s even easier to get things done in the cloud from anywhere.
Going Google
With the help of Chrome and and the growth of Google apps, people are discovering new ways to get things done faster, connect with others, and access their information no matter what device they’re using. This is what we call “going Google.” And it’s not just individual people. Schools, government institutions and businesses—big and small—are also “going Google.” Sixty-six of the top 100 universities in the U.S., government institutions in 45 out of 50 U.S. states, and a total of 5 million business are using Google Apps to live and work in the cloud.
It’s an exciting time to be living online. To celebrate this ongoing journey, here’s a quick look back at the evolution of Chrome:
None of what we shared onstage at I/O today would be possible without the awe-inspiring work being done by a global community of developers and the continued support of our users. We can’t wait to see what you do next.

Project Glass demo: Hangouts IN Air
This morning at the Google I/O conference we did a special kind of demo. I'm very proud of the talented skydivers, mountain bikers and rappellers we worked with to push technology limits while showing the amazing potential of Project Glass. Check out one of their practice jumps.
We want to share more about this demonstration with all of you, so please tune in live tomorrow—weather permitting!—at roughly 11:00a.m. PDT on YouTube.
You might just catch another Hangout in Air.

For our international readers, this post is also available in French, German, Italian, Japanese, Portuguese and Spanish (Latin America, Spain). - Ed.
A year ago we started a small project called Google+—to bring friends and family closer together, and to inspire new connections through meaningful conversation. Today more than 250 million people have upgraded to Google+, and we want to give thanks. To you. It's your support and your voice that give the service soul, and we’re grateful.
We figure the best way to show our appreciation is to keep listening and making improvements, so today we're rolling out two major updates in response to your feedback: Google+ for tablets, and Google+ Events.
Google+ for tablets: putting mobile first, on lots more devices
Back in May we introduced new versions of Google+ for Android and iOS phones. In both cases we went native (with gestural navigation, fullscreen media and face-to-face video), and it’s had a powerful impact on community engagement. In fact, more people now use Google+ from a mobile device than a desktop computer, and today’s tablet release will quicken this trend.
Of course, our tablet app isn’t just bigger, like our mobile app isn’t just smaller. It’s designed with the device in mind, and it includes:
The Android app is rolling out to phones and tablets later today (v3.0), and the iPad update is coming soon.
Google+ Events: for all the moments that matter—before, during and after
To celebrate is human. It’s how we connect with others, honor friends and family, or simply unwind after a long week. We save the date for picnics, parties and nuptials, and we cherish these moments for a lifetime. Unfortunately, the subtlety and substance of real-world events is lost online.
Today’s online event tools are really just web forms that ask, “Are you going?” Worse yet, they bail when you need them the most: during the actual event, and after everyone leaves. In life we plan, we party and we keep in touch. Software should make all of this more awesome, and that's exactly our aim with Google+ Events.
Before: send beautiful invites, and stay in sync with Calendar integration
Inviting someone to your home, your wedding or your favorite restaurant is a deeply personal act. You’re handpicking who’ll be in the room, after all, so invitees should feel part of something special. That’s why Google+ Events offers meaningful ways to build and send beautiful invitations, including:
Google+ events also appear in Google Calendar automatically, and guests’ updates arrive instantly in the stream. The end result is a useful and beautiful place to manage your party.
During: share photos live with Party Mode
Photos are the cornerstone of any great event. They get people laughing and smiling, and they let us relive our favorite moments after the fact. The challenge—especially with the explosion in smartphones—is that too many photos get stranded in too many places. We struggle to even find people’s photos, let alone enjoy them all in one spot. Fortunately, Party Mode fixes these problems with a single tap.
Once you’ve enabled Party Mode on your mobile device, all of your new photos get added to the event in real-time. And as more guests turn on Party Mode, more pictures will instantly appear to fellow invitees. In this way Google+ Events gives your party a visual pulse; we’ve even added a "live slideshow" you can proudly project during the event.
After: see everyone’s pictures in one place
Once the guests go home, it's natural to reflect on the evening's events. We reminisce about the food, or the last dance, or the sparkle in someone’s eye. And we bask in the afterglow of shared experience for as long as memory allows. With Google+ Events you can now relive the party whenever you want, with a captivating and comprehensive set of photos.
Just visit your event page after it’s over, and you’ll see everyone’s pictures and comments in chronological order. You can also browse by popularity, photographer or photo tag with a few clicks. It’s easy, immersive and awesome.
Google+ has come a long way in a year, but we know we've got a long way to go. Fortunately we serve a community that's filled with thoughtful, committed individuals, and together we're creating something special. +1 person at a time.

- A “lean back” Hangouts experience that’s great for the couch or common room
- Crisper text, fuller photos and easily-tappable actions like +1 and comment

Android @ I/O: the playground is open
(Cross-posted on the Official Android Blog)
Last year at Google I/O, we talked about momentum, mobile and more. This year, we’re picking up right where we left off. More than 400 million Android devices have now been activated—up from 100 million last June. And twelve new Android devices are activated every every second—that’s more than 1 million a day. Today, we’re rolling out a new version of Android called Jelly Bean, adding more entertainment to Google Play, and introducing two powerful—yet distinctly different Nexus devices to bring you the best of Google.
Jelly Bean: simple, beautiful and beyond smart
Jelly Bean builds on top of Ice Cream Sandwich. It makes everything smoother, faster and more fluid. For example, notifications are now more dynamic: if you’re late for a meeting or missed a call, you can email or call directly from notifications. The keyboard is smarter and more accurate, and can predict your next word. And voice typing is faster, working even when you don’t have a data connection.
We’ve redesigned search from the ground up in Jelly Bean, with a new user interface and faster, more natural Voice Search. You can type your query or simply ask Google a question. Google can speak back to you, delivering a precise answer, powered by the Knowledge Graph, if it knows one, in addition to a list of search results.
Today’s smart devices still rely on you to do pretty much everything—that is, until now. Google Now is a new feature that gets you just the right information at just the right time. It tells you today’s weather before you start your day, how much traffic to expect before you leave for work, or your favorite team's score as they’re playing. There’s no digging required: cards appear at the moment you need them most.
Starting in mid-July, we’ll start rolling out over-the-air updates to Galaxy Nexus, Motorola Xoom and Nexus S, and we’ll also release Jelly Bean to open source.
Google Play: more entertainment
Google Play is your digital entertainment destination, with more than 600,000 apps and games plus music, movies and books. It’s entirely cloud-based, which means all of your content is always available across all of your devices. Today our store is expanding to include magazines. We’ve been working with leading publishers Condé Nast, Hearst, Meredith and more to offer magazines like House Beautiful, Men’s Health, Shape and WIRED.
Now, you can also purchase movies in addition to renting them. And we’re adding television shows on Google Play—in fact, we’re adding thousands of episodes of broadcast and cable TV shows, like "Revenge," "Parks & Recreation" and "Breaking Bad," from some of the top studios, like ABC Studios, NBCUniversal and Sony Pictures. You can play back movies and TV shows on all your Android devices, through Google Play on the web, and on YouTube, and soon we’ll bring the experience to Google TV devices.
Movie purchases, TV shows and magazines are available today on play.google.com, and will roll out to Google Play on devices over the coming days.
Nexus 7: powerful, portable and designed for Google Play
All of this great Google Play content comes to life on Nexus 7, a powerful new tablet with a vibrant, 7” 1280x800 HD display. The Tegra-3 chipset, with a quad-core CPU and 12-core GPU, makes everything, including games, extremely fast. And best of all, it’s only 340 grams, lighter than most tablets out there. Nexus 7 was built to bring you the best of Google in the palm of your hand. Hang out with up to 10 friends on Google+ using the front-facing camera, browse the web blazingly fast with Chrome and, of course, crank through your emails with Gmail.
Nexus 7 comes preloaded with some great entertainment, including the movie "Transformers: Dark of the Moon," the book “The Bourne Dominion,” magazines like Condé Nast Traveler and Popular Science, and songs from bands like Coldplay and the Rolling Stones. We’ve also included a $25 credit to purchase your favorite movies, books and more from Google Play, for a limited time. Nexus 7 is available for preorder today from Google Play in the U.S., U.K., Canada and Australia, and starts at $199 in the U.S. It will start shipping mid-July.
Nexus Q: It’s a sphere!
It's great to be able to take your entertainment with you wherever you go, but sometimes you want to ditch the headphones and enjoy music with friends and family. So we’re introducing Nexus Q, which combines the power of Android and Google Play to easily stream music and video in your home—all controlled by an Android phone or tablet. Designed and engineered by Google, Nexus Q is a small sphere that plugs into the best speakers and TV in your house. It’s the first-ever social streaming device—like a cloud-connected jukebox where everyone brings their own music to the party. Available first in the U.S., you can preorder Nexus Q today from Google Play for $299, and it will ship mid-July.
If you own one of the 400 million Android devices out there, you already know that it’s much more than simply a phone or tablet. It’s your connection to the best of Google—all of your stuff and entertainment, everywhere you go. Now you have a new version of Android, more entertainment and a growing portfolio of Nexus devices to choose from—all available in Google Play. The playground is open.

Using large-scale brain simulations for machine learning and A.I.
You probably use machine learning technology dozens of times a day without knowing it—it’s a way of training computers on real-world data, and it enables high-quality speech recognition, practical computer vision, email spam blocking and even self-driving cars. But it’s far from perfect—you’ve probably chuckled at poorly transcribed text, a bad translation or a misidentified image. We believe machine learning could be far more accurate, and that smarter computers could make everyday tasks much easier. So our research team has been working on some new approaches to large-scale machine learning.
Today’s machine learning technology takes significant work to adapt to new uses. For example, say we’re trying to build a system that can distinguish between pictures of cars and motorcycles. In the standard machine learning approach, we first have to collect tens of thousands of pictures that have already been labeled as “car” or “motorcycle”—what we call labeled data—to train the system. But labeling takes a lot of work, and there’s comparatively little labeled data out there.
Fortunately, recent research on self-taught learning (PDF) and deep learning suggests we might be able to rely instead on unlabeled data—such as random images fetched off the web or out of YouTube videos. These algorithms work by building artificial neural networks, which loosely simulate neuronal (i.e., the brain’s) learning processes.
Neural networks are very computationally costly, so to date, most networks used in machine learning have used only 1 to 10 million connections. But we suspected that by training much larger networks, we might achieve significantly better accuracy. So we developed a distributed computing infrastructure for training large-scale neural networks. Then, we took an artificial neural network and spread the computation across 16,000 of our CPU cores (in our data centers), and trained models with more than 1 billion connections.
We then ran experiments that asked, informally: If we think of our neural network as simulating a very small-scale “newborn brain,” and show it YouTube video for a week, what will it learn? Our hypothesis was that it would learn to recognize common objects in those videos. Indeed, to our amusement, one of our artificial neurons learned to respond strongly to pictures of... cats. Remember that this network had never been told what a cat was, nor was it given even a single image labeled as a cat. Instead, it “discovered” what a cat looked like by itself from only unlabeled YouTube stills. That’s what we mean by self-taught learning.
Using this large-scale neural network, we also significantly improved the state of the art on a standard image classification test—in fact, we saw a 70 percent relative improvement in accuracy. We achieved that by taking advantage of the vast amounts of unlabeled data available on the web, and using it to augment a much more limited set of labeled data. This is something we’re really focused on—how to develop machine learning systems that scale well, so that we can take advantage of vast sets of unlabeled training data.
We’re reporting on these experiments, led by Quoc Le, at ICML this week. You can get more details in our Google+ post or read the full paper (PDF).
We’re actively working on scaling our systems to train even larger models. To give you a sense of what we mean by “larger”—while there’s no accepted way to compare artificial neural networks to biological brains, as a very rough comparison an adult human brain has around 100 trillion connections. So we still have lots of room to grow.
And this isn’t just about images—we’re actively working with other groups within Google on applying this artificial neural network approach to other areas such as speech recognition and natural language modeling. Someday this could make the tools you use every day work better, faster and smarter.

One of the neurons in the artificial neural network, trained from still frames from unlabeled YouTube videos, learned to detect cats.
