1.6 Control Code Specification
1 Outline
･ This printer is connected to the computer via a serial interface and
prints characters and bar codes at the requested print position on
the label.
･ The printer has a data area of 20,000 characters. This character
data can be stored in up to 400 different fields in single buffer
mode (200 different fields in double buffer mode) Each field stores
attributes such as print position, rotation angle, font specification,
and expansion factor (called attribute information). Machine
control commands for print density or printing speed setting are
used in addition to printing data control commands.
･ Basically, this printer prints labels by means of bi-directional
communications with the computer via the serial interface. The
printer not only prints data, but also transmits information such as
label and printer settings to the computer. The computer and
printer communicate so that the printer can receive correct data
from the computer and perform optimum printing.
Also, the printer has the parallel interface (centronics) as a
standard but in this case bi-directional communications are not
used, so data cannot be transmitted from the printer.
