The full list of potential problems is a long one, but there are ways to simplify and streamline everything about enterprise printing in RDS environments—which we will discuss later. Here are five common cases of RDP redirection not working when using Windows print servers and what you can do about them.
1. Print jobs disappear
This is one of the most frustrating remote computer printer problems. After connecting to the server, the client can see the desired desktop printer in the list of available printers. The client can successfully send a print job to the printer, and it even appears in the queue. But then—poof!—it’s gone, and the print job is never actually printed.
2. An installed printer is not visible to the remote desktop client
In this scenario, a printer appears to have been successfully installed on the administrative side but that printer is not showing in the remote desktop session. It might be problematic for just a single client, or it might be an entire client pool. Whatever the case, the client (or client pool) is unable to locate it and, therefore, unable to print.
3. Print jobs execute, but the text is garbled
When a print job fails to print or an RDP printer is not showing in the remote desktop session, you can at least isolate the problem to a single step in the printing process. But what about when the print job appears in the output tray with garbled text or symbols instead of text?
4. Long printing delays
Sometimes everything in the printing process will work fine. The printer is accessible, the print job is successfully relayed to the local printer, and the document prints out just as it should. However, this process will take an inordinate amount of time—far longer than it should actually take for data to travel from the local client to the printer via the remote server.
5. Application-specific RDP printing problems
This can test the limits of an admin’s sanity. Here, the end user can print from the word processor, for example, but can’t print from the accounting software. It can be a matter of one particular printer not showing in the remote desktop session for that particular application, or that a printer is accessible but the print job will not execute for some reason.
