Hi, Joseph -
If I had to guess, PB probably uses the GetDefaultPrinter Windows API function to obtain the name of the user's default printer, and the EnumPrinters Windows API function to obtain a list of all of the defined printers available to the user.
Unless directed otherwise via the PrintSetPrinter PowerScript function, a PB app will use the Windows printer that is marked as the default printer, which I believe is the behavior you are seeing. This is mentioned in the PB Help section for the PrintGetPrinter PowerScript function. While this may not be the behavior you are accustomed to, this is how PB behaves now.
It is possible to alter this default behavior by using the PrintGetPrinters PowerScript function to obtain a string that contains a list of all available printers and the PrintSetPrinter PowerScript function to change the printer that the PB app uses. Using PrintSetPrinter does not change the Windows default printer.
You may wish to enhance your app to give the user a means of identifying their preferred printer, saving this selection for subsequent use, then check the PB default printer on app startup and change it to the user's preferred printer if needed.
Best regards, John
