I know of a situation where an error message appears like the message below.
"The saved printer information is not compatible with this version of Photoshop, or the saved printer is no longer available. You will need to check your printer settings before printing"
Any such message you are getting?
If this is the case then go to Control panel under printers change the default printer. This has solved so many similar similar issues you you may try it out.
