Horizon Agent 7.12. We recently started struggling with ThinPrint (Virtual Printing) not being able to connect to home printers. I am currently testing Integrated Printing. Printing connections seems fine, but when I print to my home printer everything is delayed until I disconnect from the VDI desktop or Disconnect the USB Device. Once I do this everything prints.
What could be causing this? We are using USB Redirection and Integrated Printing.
What I've ended up doing is adding 'printer' as an Excluded Device Family in Group Policy for USB Redirection. This prevents the printer from connecting to the VDI desktop as a USB device. The integrated printing still picks up the printer since the printer is a connection to the local machine. More testing is needed as I we may be needing to switch all of our VDI pools from Virtual Printing.
I did see the job load on the VDI print spooler really quick but it never makes it to the local machines print spooler. I think the USB connection is trumping the integrated printer communication to the local machine. Just a suspicion.
