For those of you out there running 4.5 and teradici zero clients you need to know of a major issue with printers: Ghost Printers. I can repeat this with mulitple printer models and the issue does not occur on non-PCoIP zero clients. All you have to do is plug in a printer via USB into your zero client (this can be a Wyse/Samsung/Dell/whatever) and let it sit for a day or so. I see the issue most when the printer has gone into power save.
Apparently the issue is that every time the printer presents itself to the zero client it is presented with a new unique ID. I'm not sure if this is called a SID or not but that's how I think of it. Well that SID changes and due to that the printer is recreated. I have had upwards of 10 copy's on a VM. My VMs are locked down via Group Policy so its very difficult to remove the printer once it is there. We have written a very log VB script that runs as system and cleans them up. I'm happy to post this to whomever may need it, however this is an issue that needs to be patched ASAP.
I understand PCoIP is Teradici's baby and have contacted them, they need to talk to VMWare about it, and will get back in touch with me. I will post once I hear more.
