If you are using VMware’s ThinPrint solution to map printers, you may already be aware that the tool will check every 30 seconds for new printers by default. Effectively, ThinPrint is supplied with an interval, and every time that interval passes, it looks for any printers that have been mapped or unmapped from the endpoint. If it finds any changes, it forwards them to the virtual session. After that, it begins the countdown anew, and the cycle repeats.
If that standard 30 second interval is too long for your liking (and you just need to have your printers faster than that), or if it is too short (and causing too much of a latency), you can modify the ThinPrint refresh timer with the following registry value:
This DWORD value will be set to 30 by default. Simply set the number of seconds you would prefer and you’re all set.
