Epson 7800 cuts off print at about 8". Using Windows 7 photoshop CS6.

My printer suddenly stopped printing full width.  Using Windows 7 and Photoshop CS6.  I have tired on various media. Printer has worked just fine for 3 years until now.  Appreciate any suggestions.  I've exhausted what I could find online.
Thanks

Did you do any updates to computer or firmware updates on printer side?

Just regular Windows updates.  No update to firmware.

Is it cutting off at 8.5"x11"?  Also, are you using a rip?  From time to time, my preview in Photoshop will glitch and show one paper size when the backend settings are still set to another, and it will cut off the print at the smaller dimensions. If you haven't already double check in the Print Settings (and then Advanced settings if you have the option) that the paper size is set correctly there as well.

Thanks for your thoughts.  I am an experienced photoshop user and printer.  All of my settings are correct. I use odd sizes and always use "user defined" sizes.  The preview looks correct.
Any other suggestions?  Re-install the print driver?

Did you happen to try it with the last update(s) uninstalled?

So you mean the last Windows update?  I don't recall.Last update was Oct. 22 - Almost all have been "MS Security Essentials"

I'm just trying to find the point at which things screwed up and undo any possible cause.

I remember a Win 7 update that killed CorelDRAW for me some time back.
