A few days ago I could print using my usb port to a hp 1200 laser jet.  Then I tried to use my LPT1 port for a few days and now I want to use the usb port again.  I have gone through the whole trouble shooting program on windows xp and can't get the printer to print - although it did so well last week.

I have plugged the usb cable into two different usb ports.  I have gone into control panel and chosen the usb port to use.  I have restarted the computer twice.  It won't print.  Please help.  Thank you.
