Printers
The Control Center provides the required formatting con-
trol codes for the printers above when the printer is se-
lected on the PRINTER Screen in the instructions below.
These codes are transmitted through the serial interface
to the printer to provide a proper print format. Different
printers require different formatting control codes. Other
printers might provide proper operation when connected
to the Control Center. However, the print format may not
be correct or as desired. Proceed with caution and use the
following guidelines if an unlisted printer is selected:
1. All must be capable of RS-232 Serial communic-
ations.
2. Primary differences between printers involve the for-
matting control codes required by the printer. These
codes are sent from the Control Center to the printer.
For example, Weigh -Tronix printers require a control
code to select 40 column width. This same code is
interpreted by the Okidata printer as an instruction
to print wide characters. In some instances, a printer
will ignore a code it cannot interpret.
3. The Control Center requires a busy signal from the
printer when the printer receive buffer is full. This
causes the Control Center to momentarily terminate
data transmission until the printer can accept more
data. The busy signal polarity must be asserted low
when busy.
