PCOIP session showing wts protocol in TPAutoconnect

Hi,

I have a VDI enviroment with windows 7 VDIs.

I have some issues with thinprint mapping the local usb printers.

When i login with PCoIP in a session the printers are not mapped, and when execute the command tpautoconnect.exe -v -d i get this:

"C:\Program Files\VMware\VMware Tools>TPAutoConnect.exe -d -v
VCServerAPI::Init(): Protocol = WTS
TPAutoConnect User Agent, Copyright (c) 2011 ThinPrint AG, 7.17.528.1

Exiting with code.......(0)
VCServerAPI::Exit(): Protocol = NONE

"

when i execute tpautoconnect.exe -v:

"C:\Program Files\VMware\VMware Tools>TPAutoConnect.exe -v
VCServerAPI::Init(): Protocol = WTS
TPAutoConnect User Agent, Copyright (c) 2011 ThinPrint AG, 7.17.528.1

Can't connect to virtual channel (1).
Try .print Client on TC1247:4000.
Try .print Client on 10.2.2.38:4000.
No suitable client protocol found.
...
Exiting with code.......(219)
VCServerAPI::Exit(): Protocol = NONE

"

Can someone tell me why appears the WTS protocol?

Thanks,

João Areias
