Windows 10 Enterprise: 1909 Update Breaks USB Printing

Our company , Duke Energy, is in the process of updating all of our corporate computers, running Microsoft Windows 10 Enterprise, to build update 1909 (version: 18363.1139).

One unanticipated problem that we are now experiencing is with an application called Sentinel, produced by PTI Systems. It is a radiation dose monitoring software that we use exclusively for our employees who enter radiation areas on our plant sites. One module in the Sentinel software allows an administrator to register a user with a personal TLD (radiation dosimetry monitoring device) and print a label with bar scan to affix to the TLD for identifying the user whenever that user goes into a radiation area. The label is printed on a USB-connected Datamax-O'Neill 4212 Mark II label printer. On Windows 10 Professional 1709, this worked like a champ...!

The problem: Ever since we pushed the 1909 update to our computers, we can no longer print these TLD labels to the USB-connected Datamax printer. If I open the printer queue, I can see the output file flash in the queue (they're very small so it shouldn't take long at all), then disappear, but no label prints out. I've searched for this problem extensively over the Internet and it appears that this issue is not uncommon. However, I have not found a solution yet.

I have found patches to apply to 1809, 1903 and 1909 that are supposed to take care of this, but it appears that these patches are to rectify an issue stemming from the June 2020 patches (v.18363.709? something like that, I no longer have that version in front of me and we are past that version here at Duke. We're at 1909 18363.1139). I've approached our IT analyst for Sentinel; he's supposed to be testing. I've approached developer staffers at PTI Systems; they say they will begin working on testing for this, but they don't have any compatible label printers available... (?)

Our workaround currently is to go into Settings and roll back to the previous version of Windows 10 (1709 is what this computer was using). We also have a second computer experiencing this issue, but I can't get that one to roll back. In any event, we'd really like for this to work properly on our current build version, 1909, and not have to keep rolling back to 1709...

Does anybody know: Is there any kind of a patch that I can apply that will rectify this problem with USB printing on a Windows 10 Enterprise 1909 v.18363.1139 computer?
