Hi, I'm on a mac, OSX (10.5.8) using Adobe Reader version 10.1.3. I am printing via wireless to an Epson 4540 All-in-one printer. Every time I try to print a PDF, I get the following message: Paper out, incorrect loading, or paper jam. There is no jam, paper is loaded and loaded correctly. Word docs and other applications print fine, it's just the PDFs that are not printing. Thoughts on how to fix this?
