My son has sent something from his computer to our printer and instead of printing out the correct document it is printing out random characters of letters, numbers etc. Trouble is whenever his computer is connected via the home network and the printer is switched n then the printer keeps churning out pages and pages of this rubbish. Does anybody know how to cancel existing documents? I have uninstalled the printer from his computer so I assume the printer must have some print queue memory. Anybody any ideas.
