Right folks. The day before yesterday, I had a perfectly normal working Epson Stylus DX4400 printer that worked seemlessly with my MacBook Pro. I was happy. Yesterday, I downloaded the newest Epson Printer Drivers (the one linked from this Page 2 article), installed them fine. Today, I go to print using the DX4400, and it doesn't work... at all. There is an error that appears in the printer dialog box (screenshot below) Not good eh. However, incidentally, I tried using an Epson Stylus Photo R300 printer today, and that worked absolutely fine, which didn't work at all (wasn't recongized) the day before yesterday. Great. Having done a little reseach on this Apple support article, it turns out the the DX4400 has an asterisk to say that the printer's software has been updated recently... so it should be working!? But if anyone knows how to cure this problem (given the error in the screenshot above) that would have massively helpful. Thank you very much, in advance. Edit: For those interested, this issue is for all types of documents I try printing - not just the document in the screenshot. Also, when I try using the scanning function on the DX4400, I just get an "error occurred during scanning" message. While the printer does make noise, and sounds to be preparing for a scan/print like it normally would, the document is just not being sent through.
