Hi friends,
Today I added a new driver to our print server which I have done many times before, only this time in adding the new driver, all other printers of the same manufacturer (Canon) stopped working, with the device on everyone's computer showing "Driver update needed".
The new driver was for an iDV-ADV C5250. The printers which stopped working are all C5051's. The driver was added but at this point, no other action was taken, the driver was not used for a printer (hardware hasn't arrived yet) so the very simple step of adding a new driver in preparation for a new printer causes a major issue.
To resolve it on the Windows Server 2008 R2 print server, I selected any one of the existing Canon printers and set the driver to the new driver I added. Of course this did NOT work however then setting the driver back to what it was originally did resolve the issue... kind of. ALL users were then required to delete and re-add the printer(s) on their computers. You can see this was not a popular fault.
Although I resolved it, I really want to understand why this occurred. Can anyone help? I really need to make sure this doesn't happen again. I thought maybe printer isolation might help but you can't set a driver to isolated until after it's added can you?
Thanks.
