For Serial Interface Transmission Speed (DIP Switches 3/4) bps: bits per second * When DIP switches 3 and 4 are set to ON, the value (initially 19200) can be set to any of the values listed in the lower portion of the row using a command, memory switch setting mode, or the TM-L500A Utility. (See "Setting the Memory Switches" on page 45 .) 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.
