Epson R1800 printer communication error
I have a tried and tested Epson Stylus Photo R1800 that has worked for years now. Since Yosemite it fails due to Communication Error returns. It prints a couple of sheets, then fails halfway in a printout. I have reset the printer system, reinstalled the drivers, restarted my computer, canned ports, changed cables. have not used a USB hub - and so on infinitum. Time after time it stops printing in the missile of a print at times with a communication error. I use it to print large canvas prints that are extremely expensive not to mention wasted ink!
It has been a real workhorse for me - any ideas on what can be done.
