Connecting Printers
This section discusses connecting an EPSON LQ-570, Apple LaserWriter, HP
LaserJet, HP DeskJet, HP ThinkJet, or generic ASCII printer to the VM700A.
The default configuration files are set for use with the EPSON LQ-570 letter
quality printer with serial interface C 823051. The default configuration of the
LQ-570 printer is adequate for use with the VM700A. Refer to the user’s manual
for the printer for information on any changes you might wish to make to the
printer setup.
With the VM700A and printer power off, connect the serial printer cable from
the 25-pin DB-25 female connector on the printer rear panel to PORT 1 on the
back of the VM700A (a 25-pin DB-25 male connector). If you have not changed
the factory default values in the Communication Setup file, all you need to do
now is turn on the VM700A and the printer. If you have changed some factory
default values, be sure the file contains the values shown in the following
example.
The following partial listing shows the values that should be set in the Commu-
nications Setup file in order to use an Epson LQ-570 printer.
