PCoIP & Teradici

Question

Are those required?  I have a single workspace that my user connects to using the workspaces client. That workspace is domain joined.  User complains he can't switch between one sided and two sided printing so I hopped on his workspace only to find it absolutely crawling.  Looking at the running processes, I found the PCoIP process taking 90+% CPU consistently. Once I finally got access to the printer settings, I found he was stuck using the Teradici XPS driver for his Canon IR, which didn't allow him to modify any settings. Since the workspaces report as server 2016, the Canon driver I need won't install locally, although it does get pushed up from his workstation.  If I disable the Teradici service and reboot, he can't print at all, even when I switch the driver over to the one pushed up by his workstation. I can't seem to find any information on whether those are required to access the workspace, or whether it's safe to delete them.  
  
**edit** connecting from a different workstation fixes the performance issue, but all printers are still using the Teradici Client Render XPS driver which does not allow for any changes to printing preferences.  I would update the agent (currently at 2.7.x.x.x and it appears the latest is 2.14.x.x.x) but I have no confidence that won't break more than it fixes (if anything).

Answer

Short answer: yes.  
When you say "PCoIP", I presume you are referring to the pcoip_server*.exe executable that you see running.  And "Teradici" is the "Teradici XPS driver" service.   
  
The "Teradici" printer service is what allows you to print remotely, so of course if you stop it, you will have disabled all the printing.  
  
Communicating remotely to a printer is non-trivial, and in order to get the features of a specific printer you'll generally need the drivers for that printer installed on the VM side.  As you discovered, this can be problematic if the VM is running on a Windows Server OS vs the desktop.  
  
Don't try and manually upgrade the Teradici Standard Agent on your workspace.  AWS periodically checks the installed version and will automatically revert the version.  But that wouldn't help as the fundamental limitation of the printer plugin remains.

https://www.teradici.com/web-help/pcoip_agent/standard_agent/windows/2.14.0/admin-guide/configuring/configuring-tasks/ mentions a bit about the printer driver.   
  
Not much can be done unless Canon comes out with printer drivers that support Server 2016.

Thanks. Appreciate the answer (even if it's not what I was hoping for)!
