Carriage return (CR)

A carriage return (ASCII code 0Dh or 13) causes data in the buffer to be printed and the carriage to be moved to the left most print position at the same line. The following option can be selected when issuing a carriage return. Refer to the specification of your application for correct selection.

17 CR SETTING

CR: CR ONLY

CR: CR+LF

CR: AT FEED

........... Carriage return without a line feed

........... Carriage return with a line feed

........... Autofeed signal enabled

Note: Autofeed is effective for the system using parallel interface with AUTO FEED signal to control the the carriage return with or without a line feed. The autofeed signal must be low when the printer is initialized in order to add a line feed to every CR code.
