Chapter 5: Command
Command Conventions
The different features and functions provided by the printer are controlled by sending
commands from the host computer to the printer. This chapter describes the commands
that are supported by the printer. The printer commands are made up of one or more
bytes of data starting with a command control code followed by its supporting
parameters.
Commands control all operations and functions of the printer, including the following:
• Drawing by text, image, bar–code, and so forth.
• Controlling knife cut, cash drawer, and so forth.
• Retrieving the printer status and information.
• Configuring the printer to customize.
Unless otherwise noted, any of the commands may be used in any combination to
communicate with the printer from a program in a host computer.
To allow the graceful handling of commands that may be available in other printers but
are not available in this printer, some commands will be listed and described but
identified as "not implemented". If the printer receives one of these "not implemented"
commands, the command and its supporting operands will be discarded. Any other
data bytes, including unrecognized commands, are sent to the print buffer as data, and
the printer will attempt to print the data when it is instructed to print the buffer.
For more information and for the list of commands, refer to the NCR 7169 Multifunction
Printer Programmer's Guide (BCC5-0000-5352).
