Printers logon script error messages

I've been using the logon script from here that sets up network printers for months, then today I suddenly start seeing error messages.

Line:38
Char: 3
Error: The Printer name is invalid

I've checked and double checked that line and there nothing wrong with it, I can connect to the printer specified from the machines that are showing the error.

In fact character 3 on line 38 isn't even a name of a printer, it's part of a command!

Attached is the script and screenshot of the error if anyone has any ideas?

Hmm, on further investigation I got the following error "You do not have sufficient access to your computer to connect to this printer", googling came up with a MS support article about changing a setting in the local policy. Made the following change in the Domain Group Policy.

Local Policies > Security Options

Devices: Prevent users from installing printer drivers - Disabled

Forced a policy update on the machine, did a reboot, logged on and the printer script runs and sets up the right printers.

Now the only thing I can think that has changed since yesterday is some Windows Updated that were done to the Print server and clients, off the top of my head I can't remember which updates they were though.

Anyone?
