5.3 PRINTER
External Printer The ZODIAC 901 Middle-Ear Analyzer is equipped with a thermal
printer as standard—it may, however, be supplied without the built-in
printer. Whether you have a built-in printer or not, your ZODIAC 901
has a parallel port on its rear panel for connection to an external printer.
Default installed in ZODIAC 901 is the HP generic Laserjet printer
driver which can be used together with any printer where PCL may be
selected. A Centronics cable for connection to a printer may be supplied
as an optional accessory. Other drivers for external printer may be de-
fined by means of ZODICON™, e.g. Epson FX, HP Deskjet 500 and IBM
Proprinter.
MIDIMATE 622 In addition, ZODIAC 901 may be connected via the RS232C Data Inter-
face serial port to the MIDIMATE 622 Audiometer, to allow the MIDI-
MATE 622 to print out audiograms on ZODIAC 901’s built-in printer or,
