Serial Option, TTP 7030
The printer has a 10-pin connector on the control board. This connector can be used to connect
to an external RS-232 adapter. See Connecting To The Computer on page 16 for installation
instructions.
The transfer speed of the serial interface can be set to between 2 400 and 115 200 bits/s.
This low transfer speed limits the printing speed. Printing full-width graphics with 115 200
bits/s result in printing speeds of about 24 mm/s for the 80-mm version of the printer, and
16 mm/s for the 112-mm version.
Applications where text-only printouts are to be printed are suitable for serial interface
because of its easy to use bi-directional capability.
