Chapter 3 Advanced Usage When a Serial Interface is Connected DIP Switch Bank 1 For DIP switch 1-2 (Receive buffer capacity), see also DIP switch 2-5 (Sets the release condition of the receive buffer BUSY state.) Transmission Speed (DIP Switches 1-7/1-8) 3 bps: bits per second * The default value of transmission speed set with software settings is 38400 bps. (See "Software Settings" on page 59 .) Depending on print conditions, such as print duty, print head temperature, and data transmission speed, print speed is automatically adjusted, which can cause white lines due to intermittent print (the motor sometimes stops).
To avoid this, set the transmission speed higher or keep the print speed constant by setting it lower. 55 SW Function ON OFF Default setting 1-1 Data reception error Ignored Prints “?” OFF 1-2 Receive buffer capacity 45 bytes 4 KB OFF 1-3 Handshaking XON/XOFF DTR/DSR OFF 1-4 Word length 7 bits 8 bits OFF 1-5 Parity check Yes No OFF 1-6 Parity selection Even Odd OFF 1-7 Baud rate selections See the " Transmission Speed (DIP Switches 1-7/1- 8)" table below.
