I have a Windows 2000 Terminal Server that has been working fine for some time. It has printer drivers installed so that users can print to two servers that are installed as Network Printers on the Terminal Server and other drivers that are installed so they can use their local printers that get mapped. The majority of these drivers have been PCL5 drivers.
However, recently another Administrator installed a new network printer on the Terminal Server and he used the PCL6 driver for that printer. Everything seemed fine until we rebooted the server last night. Now, the printer with the PCL6 driver works fine however all of the other drivers fail to print. They don't give very detailed messages at all. For example, when I try to print a test page it just says there is a problem with the drivers. I have tried reinstalling the drivers for the printers that aren't functioning with no luck. I even tried removing the new printer and its drivers (through server properties -> drivers) and reinstalling the drivers for the old printers and that didn't work.
At this point I have no idea why the old printers won't print or where to look to find out more information.
