Hello ,

Using 8.4 2111 would be solution here

Horizon Agent =8.3 and below ==> %P (*) --> only * option was customizable Horizon Agent

Horizon Agent 8.4 [2111 ] and above ==> %P* --> We can customize the name we want or keep the exact same name matching the client printer name by just keeping the %P

It works for both RDSH and VDI desktop agents.
