Photoshop error message: must install printer

Hello,

I am new to this forum.  I'm using an old Photoshop version with Windows Vista.  I have always been able to print images with no difficulty until the last few months when I get the message about "must install a printer".  My printer works fine and prints other documents from a variety of platforms.  It seems to be just Photoshop.  I'm wondering if it no longer supports Vista or if there are other suggestions.  Thanks in advance.
