Hi Maria,
What versions of AR, AP and Invoices are you using?
All default printers are set in Adagio from the File menu and Workstation Options. If you are running an older version of Adagio, this would be in File / Options (if you don't see a Workstation Options choice). Try setting the default printer in AP, AR and IN.
The default printer is saved in the Windows Registry, which means you need enough workstation rights to save in the registry. GL is no different than the other apps, but something to consider if you are trying to change the default printer and it isn't being saved as expected.
