Table B (shown earlier) has the DIP-switch settings for auto interface selection, parallel interfaces, and for serial interfaces with odd or no parity. When the auto interface selection is selected, the printer determines which interface receives data and then switches to that interface until the end of the print job. (A print job ends when no data is received from the selected interface for the amount of time specified by the auto interface wait time setting.) If you don’t know what type of interface your computer requires, check your computer manual. Also check your computer manual to make sure your computer and printer have the same parity setting.
Serial bit rate
Besides selecting the interface and parity, if your computer is set up for serial communications you may also need to change the serial bit (also known as baud) rate setting. The serial bit rate is the rate at which the printer receives data from the computer.
Table C (shown earlier) has the DIP-switch settings for the printer’s four bit rate settings. Check your computer manual or application program for the correct serial bit rate setting. Your computer and printer should always be set to the same bit rate.
Page length
To set page lengths other than those listed in Table D (shown earlier), see the printer commands in Appendix B. Be sure to set the page length to match the paper you plan to use.
