Although both Windows and Mac have built-in font viewers, there are quite a few utilities that do a better job, many of them free. I like Font Picker, a free download that runs on Adobe Air for both Mac and Windows. For more typography tools, read Lifehacker .

Rasterbator is a free service that creates huge mural-size images from any picture. Simply upload an image, and then download and print the resulting multi-page PDF. Re-assemble the pages and you will have an extremely cool looking poster that can be as tall as sixty-five feet. If your original image is more than a megabyte in size, you’ll want to download the free Rasterbator Windows utility instead of using the online service.

Got photos? Got CDs? How about creating a cool CD cover from your own photos? This fun tool from Flagrant Disregard will create a personalized, printable page that integrates your photo and text into a CD or DVD cover that you simply print, cut, and fold. You can upload a photo from your own computer, or use an online photo from Flickr or your own website.

Instead of throwing away printer paper that’s only printed on one side, stack it next to your printer and use it for rough drafts. Another way to save paper is to print two pages on a single sheet of paper. For Windows instructions, read this. Or for Mac, try this.

If you have an ink-jet printer, you can create one-of-a-kind t-shirts with iron-on transfers, which cost about $11 for a package of six sheets. You can use any graphics software to make your design, but Hanes offers a free software download just for t-shirt design called Hanes T-Shirt Maker Lite.
