How can I fix my HP7450 Printer it keeps jamming?

hi

I assume your PC meets minimum spec...

If problem occurs from all applications then reinstall printer driver.
If using PCL 6 - try PS
(drivers and support info here ........

If that doesn't work try using another driver instead to test it - I always use the Adobe Universal printer driver to test printers (although it does not giving finishing options it works on all printers).

Good luck.
