Apple Macintosh LC 630 DOS - Manual (Page 66)

Using Macintosh peripherals in the PC environment
You use the serial ports of your Macintosh just like the serial ports of any
PC-compatible computer.
The maximum data transfer rate supported by the DOS-compatible hardware
when a COM port is mapped to a Macintosh serial port is 19,200 bits per
second (bps). If you’re capturing serial output to a Mac OS text file, there is
no limit.
Using printers
For DOS or Windows printing, use the LPT1.DOS or LPT1 serial port. In
general, you must use printers that are Macintosh-compatible and use their
corresponding printer extension for the Macintosh. However, in a PC Novell
NetWare environment you can print to a PC-compatible printer attached to a
Novell network. See Appendix E, “Installing Network Management
Software.”
DOS uses the printer selected in the Macintosh Chooser as the default LPT1
device. If you have a serial printer directly connected to a COM port,
however, DOS uses that printer instead.
The DOS-compatible software can process output for Epson and PostScript
printers, and for all printers that use Hewlett-Packard’s page control
language (PCL).
QuickDraw printers such as the StyleWriter or ImageWriter work only with
Epson emulation. (If a printer is not a PostScript or PCL printer, it’s
considered to be a QuickDraw printer.) For non-PostScript PCL printers, use
the appropriate PCL driver in the PC environment. For non-PostScript,
non-PCL printers, configure your DOS application program to use the
Epson LQ-2500 driver. If this driver isn’t available, try another Epson LQ
or LX series driver. Be sure to turn on the PCL option if it’s available for
your printer.
