I updated a print driver for a Canon IR 5051 printer on our Windows 2008 R2 print server. I changed the one printer on that print server to use the new driver. Within 15 minutes I started receiving phone calls from users saying they were receiving a warning to Update their Print Driver. The warning was happening for multiple models of Canon printers (Attached is a screen shot of the warning)
I immediately set the printer back to the previous print driver and removed the print driver package from the print server. However some users were still receiving the message to update the print driver when they sent a print job. Clicking Install did not update the driver either, we had to remove a printer from their machine and then add it back manually from the print server, it again would prompt to Install the print driver which we did and that would resolve the issue for all the Canon printer models on their machine.
We do have the GPO in place for Point and Print Restrictions and set it to "Do not show warning or elevation prompt", this has been in place for some time. Also this occurred before any patches were applied yet this month to either the PCs or the print server.
From Google searches it appears the only way to resolve the issue is by what we were doing but my question is why updating that one specific printer driver caused several models of printers to require a driver update.
Any help on this would be greatly appreciated.
