Preview not using default printer
At 1 customer, we are having an issue where after previewing a report, and clicking print, the printer selected is the first printer, not the default printer.
Customer is using Terminal Services.
I recommend upgrading to RB 20.03.
Starting with Windows Server 2016, MS broke some API compatibility for getting the default printer. This is likely the issue you are encountering. RB 20.03 does not have this issue.
