In many enterprise printing scenarios, including remote-desktop environments, printer redirection is a commonly used print-management strategy. But the reports of redirected printers not working are frequent, and there are numerous glitches associated with printer redirection that cause problems for admins and end users alike.
For starters, what is a redirected printer, anyway? The basic explanation is that it’s a local printer that’s mapped on a remote machine. Mapped this way, users can print to their nearby physical printer even if they are logged into a session that is hosted on a distant server. This is one of the most common scenarios—printer redirection used in remote-desktop or virtual environments.
As you might expect, the link between the remote session and the local environment is more difficult for the software to negotiate than your typical end user expects or understands. For the most part, end users don’t really care what a redirected printer is or how printer redirection works in a remote desktop—they just want to know why clicking “Print” isn’t getting their documents to the printer down the hall.
Of the many issues caused by printer redirection, one of the most common is seeing these printers hang around even after they’re removed through the standard protocols. End users keep banging their head against the wall—trying to print to these devices—only to find that the redirected printers are not working because they don’t actually exist. What’s more, from a print-management standpoint, it’s incredibly frustrating to see something you’ve deleted keep reappearing—not to mention it can lead to confusion over spooler crashes and, in some cases, printing downtime.
If you encounter this issue with printer redirection in remote desktop with Server 2008/2012 R2, the first thing you can try is finding the print-spooler folder. Then stop the spooler (that’s really important), delete the contents of the folder, and restart the spooler. That often purges the deleted printers and solves some basic issues with redirected printers not working. If the redirected printers reappear, try deleting them again though the usual method. And if that doesn’t work, try changing the owner of the printer to Administrator (under Properties), resetting the permissions, and then deleting once again.
When the problem is more serious, you’ll need to do some registry edits. I’m obliged to warn you that registry-level changes—not just those related to printer redirection in remote desktop—can really mess up your system, so please make sure you have a fresh backup in place before attempting this approach. In three steps:
I’ve described some of the most common ways to address printer-redirection problems. That said, none are guaranteed in every case to solve the problem or prevent it from happening downstream. To avoid printer redirection problems for good, you’ll want to take a look at our next-generation print management solution.
That’s where PrinterLogic can make life easier.
