Virtual Printer driver can print directly to a local printer. This makes it ideal for receipt printers.

This new add-on requires a one-time printer driver installation on each workstation.

Virtual Printer is not supported with HTML5 connections.

Universal Printer Driver does not require any installation on the client side.

Universal Printer driver also works with HTML5 and doesn't need to install a driver.

We find that some of our users that insist on using RDP sessions, instead of the TSplus generated client like this Virtual Printer add-on and we have been getting good feed back from these users.
