There are a hundred ways to do this, many are tedious, lots involve a lot of manipulation on your part. This is so easy a caveman can do it. This program has been mentioned here before, but it's been about 5 years and never been in tips and tricks so thought I'd post it up. Posterazor http://posterazor.sourceforge.net/ It's a free program available for mac or PC that automates the process of splitting an image into multiple sheets in order to get far larger then your printer can handle. You can just put in an image, decide the size and you're done. The only thing you have to watch is your margins. You'll have to set them in the program you print from as well as in posterazor. To start I set all mine to zero and print a single page to figure out the actual unprintable area on my printer. Which turned out to be .125" on my printer. So i set all margins to that. Be sure to use the same orientation also. Now you can tile out an image to as large as you want, you are only limited by your ink and paper supply. This is the best part, Working with your projector I have a projector as many of us do, however the other really cool part here is , say you need to cut a stencil for one little part of the image. Just measure the projected area, posterazer the whole thing to that, pick your page with that part on it and voila. No messing with figuring out how much to scale up part of the image to match what you've projected it to.
