The Control Center provides the required formatting
control codes for the printers above when the printer
is selected 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 communica-
tions.
2. Primary differences between printers involve the
formatting 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.
PRINTER CONNECTIONS
Connect the printers to the Control Center Microboard
as follows. Only one printer can be connected at a time.
