print job stuck in que for printer hp psc 1410 all in one printer

I have an hp psc 1410 and i am connect to it through a network. Lately a
bunch of print jobs get stuck in the que and will not print or delete. i can
select pause and it will say pause and then i can restart and the pause will
go away but it doesnt print. if i hit cancel it will say 'deleting -
printing' if i hit paus after that it says 'paused - deleting - printing'.
but it just sits there.

i thought it was only happening when i was printing from a certain program
and now it happened when i printed from the internet. nothing will print from
any computer now. i dont know why in the past the job cleared. i restart the
main computer and my computer, i restart the printer. i let the computers and
printer sit turned off all night and in the morning it isnt cleared. ive
tired 'cancel all documents' from the main computer and my computer. nothing
seems to work.

the last time i couldnt get the que cleared, i had to uninstall and
reinstall the printer on the main computer and then delete it from the
printers on this computers network and reinstall it there as well.

is there a reason it is getting stuck? how do i get it out? thanks
