I work in a Mac enviroment and have been using the Xerox Phaser 5400 for about a year now. The other day when I would try to print to an 8.5 x 11 or an 11 x 17 it would print the images larger than what it should be. it did this in both Illustrator and Photoshop. If I saved it as a PDF it would print the right size in Acrobat. It used to work fine, but now no matter what I have tried, it won't print the correct size. Everything is huge. If anyone knows how to fix this that would be great.
