Error message: Printer selected not valid??

I get this error message when I try to print a report from the report
preview window.  What do I have to do to correct this? I don't know what
I did to get this error! I have other reports that print from the same
screen that don't give me this error.  I even made a new quick report
but the new one gives me the same error.  Why will the other report
print but not this one?  Any help most appreciated.
