Hi - I posted a question a few days ago (see below) and I have received no responses. Did I post in the wrong forum or does no one have any helpful hints for me? I really need help.... Thanks! Wondering if anyone can help me with a problem I am having printing from my iMac (v10.7.4 Lion) to an Epson Workforce 610 printer/scanner. I got so fed up with feeding ink into my Epson stylus photo 1800 printer that I decided to connect (via wifi) to another printer, the Epson Workforce 610. It worked beautifully for a day or so. Then it just wouldn't print anymore. I can use the scanner successfully but the printer gives me the following error code: /Library/Printers/EPSON/InkjetPrinter/Filter/pdftopdf.app/Contents/MacOS/pdftopdf failed I tried downloading the latest printer drivers. I uninstalled and reinstalled the software that came with the printer (it's a few years old). I tried everything I could think of but I still can't print. I don't understand how it could work one minute and error the next minute. Very frustrating. The printer works fine when used via our other computer, a PC. And, as I mentioned, the scanner function works fine from my mac. If anyone has any thoughts, please share. Thanks!
