IF YOU HAVE MORE THAN ONE ATARI PRINTER
You may connect two Atari printers to the computer at the same time However. ?he printer handler built into the Operating System can control only one printer at a time Therefore, to avoid errors, mate sure you turn the power on to only one printer at a time
You may switch printers at any time, even with the computer turned on.
If you have no printer connected to the ATARI 850 Interface Module parallel printer port, or if that printer is turned off. then theInterface Module will not act like a printer, and you may use another printer connected to the system.
