I have a Mitsubishi CP9550DW photo printer, it's the kind that theme parks use for souvenirs - It provides very quick printing of 6" x 4" photos which are instantly dry.
The printer is usually attached to a touchscreen Windows 7 (x64) - However, just recently the print output colours have been very poor and it makes subjects look very tanned is the best way I can describe it.
The original images look fine on screen, so I offloaded them on to my laptop (Windows 7 x64), hooked up the printer (with latest drivers from here http://mitsubishi-imaging.com/cp-9550dw/
) and the output photos are of the quality I would expect.
So clearly the issue lies with the Touchscreen PC but I have no idea what? Obviously I've tried the same drivers as my laptop - I've also uninstalled the only other printer (Microsoft XPS) available on that PC and removed any reference just in case there was some kind of conflict there. I've also tried all available USB ports and removing the printer and drivers and re-installing those from scratch.
I maybe should add that the PC's sole purpose is to process photos, it is never attached to the internet and windows updates are disabled. The only thing which has ever been updated are the printer drivers. Thinking about the issue it's always happened but a lot more infrequently than now so I don't think a system restore will help.
I think my next option might be to reinstall Windows but just wondering if anyone has any suggestions before I do this?
