I am having a bizarre issue with an end user who is unable to print to a USB attached printer.
The environment is as Windows 7 machine with a Canon Pixma iP90 printer. The driver is installed (and has been re-installed several times), but whenever a print job is sent the printer spools but no printing ever occurs.
The following is some relevant information
I can confirm that the printer is spooling as the spool folder fills up, and the job "releases" and the spool folder empties
I have turned off print spooling with no luck
None of the features from the Canon utilities (ie Turn Printer Off) features work
Computer recognizes the printer as being installed. When the cable is unplugged the printer icon grey's out in Devices and Printers
Printer and cable are confirmed working as they work with other PC's in the office
I have deleted the USB Root Hub devices and rebooted the machine with no luck
No error messages are displayed or logged in the event viewer.
The Canon diagnostics utility doesn't detect any problem and states the printer is functioning properly
Printer is not shared
User is able to print to other shared printers in the office
Any help with this issue would be greatly appreciated.
