What Im saying is sometimes I forget to check that what I have it marked for on the screen prior to the Print Preview window....Ive printed to PDF on a prior clients return and it saves that setting on the next return, so when I try to print the next client it seems like nothing prints when in fact its printing to PDF.

Double check that you have the Printer box marked on the print window prior to going into the Print Preview screen.

For other weird printing issues a reboot of both printer and computer seems to cure the problem.
