Last updated 9 months ago

Printer redirection can be slow at times, which manifests itself in users waiting until printers are redirected on logon. To improve user experience, Parallels RAS 17 introduces a new feature where user printers are not deleted from a user session on user log off and can be reused in the future.

Take a note of the following when using this feature:

  • On user logoff the printers are kept in registry, but user permissions are recalled.

  • On user logon, the permissions are provided again, and printers become available immediately.

  • Enabling this feature becomes especially beneficial if Wait until all RAS Universal Printers are redirected before showing the application option is required to be enabled in Publishing defaults.

To enable printer retention, in the RAS Console, select the Universal printing category and set the Printer retention option to "On".

Use case scenario

45+ printers are defined on windows 10 and Wait until all RAS Universal Printers are redirected before showing the application option is enabled in Publishing defaults:

  • Printer retention is set to "Off" — on every logon it takes 27 seconds from the moment the progress bar with printer redirection appears.

  • Printer retention is set to "On"— only the first logon takes 27 seconds from the moment the progress bar with printer redirection appears. Every consequent logon takes less than 2 seconds from the moment the progress bar with printer redirection appears.

Parallels recommends

Enabling the Printer retention option may greatly improve user experience, especially if the Wait until all RAS Universal Printers are redirected before showing the application option is enabled in Publishing defaults.
