On HP Thinpro based Thin Clients, locally added printers disappears after reboot.

Symptoms:

On HP Thinpro based Thin Clients, locally added printers disappears after reboot.

In VDI environments, locally attached printers can be used in two ways. "USB redirection" and "printer redirection".
For USB redirection, Printer driver must be installed on VDI desktops (master images in case of Non persistant VDI)
But Printer redirection allows the user to add local printer to VDI desktop without install driver on master image.
In printer redirection, drivers has to be installed on the Thin clients. locally added printer will be redirected to remote VDI.

But whenever we add local printer to an "HP Thipro Based Thin Clients" (HP T5740, T520), it is observed that added printers are disappearing on each reboot.

Solution:

After adding the printer on ThinPro control pannel, reboot the "CUPS" service (Common Unix Printing System)

Steps:

1. Add the printers from "Administrative Mode > Peripherals > Printers.
2. Go to "Administrative Mode > Advance > X Terminal.
3. type, "service cups restart" and press enter.
4. Reboot the Thin Client and ensure recently added printer existing.
