check the cables to the printer. turn the printer on and off. reboot the computer and the printer by unplugging it for 30 seconds then replugging it in
check under printers and faxes for the printer right click on it make sure that it does not say use printer offline
double click on it. delete all jobs in the queu
can you print a test page directly from the printer ? if not there is a physical problem with the printer tell me if there are any lights flashing etc etc.
you have not told me what operating system you are on.
go to this link download and save the correct driver for your operating system.
unplug the usb connection for the printer
go to printers and faxes and highlight the printer and hit the delete button to delete it
run the software that you downloaded
do NOT reconect the printer to the computer until the software installation asks you to or it is succesfully completed.
when you plug it in try to use a different usb port then the one you have been using. check the usb plug is secure at the printer end as well unplug it and plug it in again
leave the spooler alone. you cant print without it. i am not even sure how you go into the print spooler and delete directly from there. delete jobs from the printer driver in priner and faxes. heck that may be the thing that screwed it up if the driver thinks there are jobs to print and the spooler doesnt have them to pring
delete everything reboot everything and reinstall it just the way i said to using new drivers.and a different usb port
check the device manager go through it and delete everything that has a yellow or red mark on it
then reboot see if they get reinstalled correctly
see if you can print a tet page directly from the printer
if it worked a few days ago try doing a system restore.
or the usb port. or the printer
check the device manager try deleting the usb ports and rebooting and letting it reinstall them.
