Local printing from remote machine

[featured_spectre]

OK. We have 4 servers located around the world. All clones of each other (with minor software tweaks for the local currency and obvious IP changes), they speak to a main server located in the UK. All servers can print from the UK via remote desktop, apart from Canada. They're all identical in terms of settings, and local settings are identical.

 

Printer options show that it *should* print to a local printer, however it isn't. Everything online points to the options in MSTSC or on the server remote desktop management software, but they all have the correct settings (and identical to other servers we have). It just doesn't show any local printers on the remote machine when MSTSC is running...at all. It shows the printers at the other end, but nothing this end.

 

Any suggestions? Registry issue perhaps? I am out of ideas, so posting here.
