PC XP SP1 512RAM 1.7/2.1 Athlon 80GB HD. Epson printer stopped printing and at one point error thrown up with DLL file missing dont know which one it was, went thru MS troubleshoot road no joy contacted EPSON didnt want to know, really helpful that, thought Id contact MS to try and resolve and guess what £34 just to contact them, brilliant. Reloaded software a number of times, rewound to earlier time with restore nothing happening. Every time send to printer looks as if it is happening then message comes up this document hasnt printed. Printer port checked seems to be OK, I think it would be helpful if there was a website where not only DLL files were but also identify what they were for as well.
