you really haven't given us any useful information.
print spooler crash, ok - that is actually pretty common. if it happens regularly it is (hopefully) your drivers are corrupt, try removing and reinstalling the printer.
if still no go, what are you trying to print? certain printers and win 7 have problems with PDFs, especially large ones. in the print options under advanced choose print as image and that should bypass the pdf issue.
if neither of those are it - then it is one of the other thousand things that can cause a spool crash. more info needed. printer model, age, etc. other issues. how long has it happened. do you have any other hardware to troubleshoot with (another printer/computer, etc?) also scanners and digital cameras can affect the print spool, pretty much any digital imaging device CAN , though if the drivers are proper they shouldn't.
