Using a Standard RS-232 Printer
It is possible to interface a standard RS-232 (serial) printer
to the power supply. However, specific requirements must
be met by the printer to ensure compatibility.
The serial printer must have the following
minimum capabilities:
D
printing ASCII characters
D
have a 40-character column width
D
baud 9600
D
stop 1
D
parity none
D
data 8
D
buffer > 200 characters (suggest 2000)
See Figure B-22. Use the cable pin designations in the
table below to create an interface cable. Note that the table
describes the signal wiring on the B side of the cable. The
B connector must have male pins to properly mate to the
printer connector. The A side of the cable is wired to
RS-232 standards.
