Problem:
Would like to use the PRINTER_REDIRECTION=TRUE routine
Resolution:
Release: 3.1
In order to see the print dialog box, you need to call the PC_PRINTER_OPEN routine - this will then allow you to Open a printer channel, giving it a document title, and optionally displaying printer control, font, and progress indicator dialog boxes
Full details of how to implement this are in the Net Express help, under PC_PRINTER_OPEN.
