my computer sends printing commands to the printer but the the printer is not printing out anything.

the printer name is HP LaserJet Pro 400 MFP M425dn. it was working all along with the same connections and set up but today it does not want to print out any document

1) first test a self test page using printer ( for confirm printer working condition)

2) Test with another computer if available ( to isolate the problem)

3)  Please check for  corrupted spooled jobs ,  Can see corrupted  files in this path "C:\Windows\System32\spool\PRINTERS" ,  if yes, have to delete those files after stopping printer spooler service.

Thanks.
