Html printer can't use with RDP

Html printer can’t together use with 2 windows user. If first user login ,second user can’t use, only first user can be use, second user show error, how to fix it? Ticket printer not have that error.

From sounds of that your using an RDP patch to allow multiple RDP connections? Or do you have a server versions of windows with multi RDP licence?
If using a patch… well, its NOT a recommended solution as well as being risky and is likely a trade off for using a patch.

Intrigued on what your doing? Is it just to html format your template or are you doing something for customer display?

I have exactly the same problem but I am using Windows Server 2012 with RDP. I have 2 tablets connected via rdp. Each will print kitchen orders when it is the only one connected. As soon as they are both connected at the same time though only one will print. The other comes up with the error above.

The tablets log into the server with two different accounts. Any ideas?

Thanks!
