UniPrint could not find a suitable way to transfer your print job to you
This usually indicates a virtual channel issue between the server and client. Please contact our UniPrint Support team to determine the specific root cause.
How hard is this to implement in the Azure environment?
It’s actually really simple, as the only new server that you would need is the Bridge server for UniPrint. If you’re looking to consolidate the print server into the cloud then you would already have the additional servers needed. And the application servers would also already be in the cloud, so you would only have to install the UniPrint components on the appropriate servers.
What is required to have a print server at a remote site while the application and bridge server is located in the Azure Cloud? Does it require a VPN?
No, no VPN required as long as the Bridge server is accessible via an external IP address. We do require a port to be open back in the datacenter so that the remote print server can communicate back to the Bridge server.
Control UniPrint License Usage
Application Product: UniPrint Infinity
Symptom: Users get watermark when printing.
Cause: All UniPrint licenses are used up by users that have a session on the Terminal/Citrix server.

- More UniPrint licenses may be purchased.
- Allow only users that need to print via UniPrint access to logscrpt.exe (9.0.6 or earlier) or UPSession.exe (9.1 or later)
- On the TS/Citrix server go to C:\Program Files\Uniprint Suite\LogScrpt.exe (9.0.6 or earlier) or UPSession.exe (9.1 or later)
- Bring up properties for logscrpt, click on the security tab.
- Remove the Users security group.
