PIXMA MG6450 Another computer is using the printer

[Yatesy1990]

Up to now we've printed ok but yesterday our Windows 8 laptops report that "Another computer is using the prnter". We have a Canon MG6450 printer; ona  wireless network. We have rebooted our laptops; the router; and switched off printer but to no avail. Any other suggestions ?

Another computer is using the printer.
The following status is the usage status of that computer.

Creating print data

A follow up query is why is there a need to register is the need to send email docs to [Email address removed in accordance with forum guidelines] to get printed ? It is both time consuming, over elaborate and completely unnecessary to use a "Print from E-mail" service and " to complete the printer owner registration".

I got down to the change timeout settings and it gives message "cannot change setting?"

It worked! Thanks!

Installation installs only one printer device, and it is ....WS. So I cannot choose another.

I uninstalled and reinstalled the printer. Now a print command does nothing. No error message. Nothing.
