I have a machine that has two dot matrix printers attached locally, one on LPT1 (Epson LQ-870) and the other on LPT2 (Epson LQ-850), also a network printer on LPT3 (HP Laser). I currently have the 'HP Laser' set as default. When trying to print to 'Epson LQ-870' I issue the command SET PRINTER TO NAME 'Epson LQ-870' but when I send the print job it still goes to the HP Laser printer. Why? Can I set the default system printer programatically, if so how?
