5.2 Printer Configuration Commands
The following commands are used to set up printer configuration. Most of these commands
are non-volatile and, therefore, do not need to be resent unless changes are desired.
Note: When the printer is in the DEFAULT MODE, factory settings control printer operation.
This provides a starting point for re-establishing communication with the printer so that user
settings may be sent to the printer. The statistics label printed when the printer entered the
DEFAULT MODE reflects current printer settings and not the factory default settings.
5.2.1 Software Switches
The Software Switch settings are non-volatile. The Switch commands may use either ^A
(decimal) or ^AB (binary) values. Since each bit represents a setting for the printer, the soft
switches are always reported as binary. Changes made with these commands will not take
effect until the printer's power is cycled "OFF" and "ON", a "reboot" command (^A1^D143),
or a "soft restart" command (^D32 command) is sent to the printer.
Example: ^AB10100001^D21<CR> configures serial port #1 for text equivalent
enquiry responses, accept control codes, disables echo, and enables XON/XOFF
flow control.
5.2.1.1 Software Switch #1
^AB ^D COMMAND
XX 21 Change SW1: Software Switch #1.
^AB12345678 (each bit is represented by a numeric position number)
Position:
1,2 Enquiry Response: This determines what the printer will send back in
response to an enquiry command.
3 Control Codes: This position sets how the printer handles incoming
control codes.
4 Port #1 Parity Selection: Sets the printer port #1 parity for serial
communication.
5 Port #1 Parity Enable: Turns printer port #1 parity ON or OFF for serial
communication.
6 Echo: If this feature is enabled, the printer will echo all received
characters to the serial port.
