SP1900 Plus

DIP Switch Settings

The SEIKOSHA SP-1900Plus printer uses the following Dip Switch settings. Please refer to the printer manual for details of how to set these printers up.

Note: The printer must be turned off before you can change any of the switches. The current DIP Switch settings can be printed by holding down the NLQ switch whilst turning the printer on.

If you have been printing, allow the Print head to cool down before touching it. When setting the switches (below), open the printer cover, remove the ribbon cassette and replace the printer cover. The DIP switches are only read after the initialisation process either by turning the printer on or by receiving the INITIAL signal via the Parallel Interface.
