DIP switches 2 to 8 are for serial communication. Not used in parallel communication.

Note:

When using an OPOS or Advanced Printer Driver, do not change the DIP switch 1-1 from the OFF position (power supply switch enabled). The printer may not operate normally if the DIP switches are set to ON.

When you set the baud rate with the memory switch, you can set faster communication than with the DIP switch. (Refer to “Communication Condition” on page 2-29,Error code” on page F-3)

In serial communication, intermittent printing* may occur. This is because when the communication speed is low, a data transmission waiting state occurs frequently since the printing mechanism speed is high. Increasing the communication speed may reduce this symptom.

* Intermittent printing: White streaks as large as one or two hairs appear horizontally in a printing result.
