One of the reason why printing may slow down is Print2RDP temp files accumulate in the temp folder.
Print2RDP Clients version 6.26 and older version were affected by an issue where in some cases temporary files were not deleted from the system. Temporary files stuck on the system could cause the printing to slow down or fail when printing longer (multi-page) documents. This issue has been solved in Print2RDP Client version 6.27. To solve the issue permanently, please upgrade to version 6.27 or later.
The temporary files are stored separately in each user’s temp directory. The temporary files generated by Print2RDP have a name beginning with “epa” followed by up to 4 characters and have an extension of .tmp (e.g.: epaE452.tmp). To clear the temp files for a user on the system, please follow these steps:
Disconnect or Log off from all RDP sessions.
Open a Command Prompt.
Type in the following commands:
cd %temp%
del epa*.tmp
Print2RDP version 6.27 or later generate the temp files in the Print2RDP subfolder of the user’s temporary directory. There should not be any files in the directory unless printing is in progress.
