OK, it's even stranger...
My client is using OE 8.1F (150227) and EP 9.0A (150326). They have 10 workstations and 2 datasets. All workstations present the same symptoms. However, for one dataset it prints to the default printer and is not written to a PDF, whereas for the second dataset it prints to the default printer and is ALSO written to a PDF!
The company profile settings under the Reports tab in OrderEntry for the two datasets are identical. Force paperless reports is not enabled; they are clicking on the EP icon, not the Print button.
Under OrderEntry | File | Workstation Options, a specific printer has been selected for all forms, and interestingly it is NOT the printer that the forms are actually getting printed to - that setting is being ignored and the output is going to the default (local) printer. Of course, it shouldn't be printing at all!
Nothing has changed in the environment in a long time, no new workstations/servers, no software upgrades, etc. It just started happening all of a sudden.
