Good Morning!

We recently upgraded to PB 2019 and had some complaints from our users in the Citrix environment where their default printer was not being set correctly.  At the time we tried to implement a suggestion found here by adding an option that our application would call an extra windows printer API when opening to determine which default printer to use but that didn't seem to help.  We then found an option in Citrix that tells the application to start without waiting for default printers, we turned this off which causes a minimal delay but the default printers were now available. 

One clientis still having an issue and has been working with Citrix directly but was hoping for some guidance as per a request from Citrix to have a phone call.  Here is the information they are looking for and I was hoping someone could help answer this as to how PB is looking for the printers.  I saw in another thread The PB run-time just calls the equivalent "Enumprinters" command API in the O/S ( https://docs.microsoft.com/en-us/windows/win32/printdocs/enumprinters).    Is there any other information that could be provided that may be helpful to them?

From our client:

So right now we have our VDAs working on the LTSR version (1912) but we are unable to upgrade to the latest VDA versions starting with 2003. Below is what Citrix would be looking for on the call.

“The goal is to have the vendor explain what their application is looking for to enumerate a printer in their application. Are there registry keys or values the application is looking for that are present in VDA 1912 sessions that are not present in VDA 2003 sessions? This is the level of information we need from the application vendor. This way, I can go to our engineering team and ask why these particular settings/values in the LTSR branch differ from the CR branch.”
