Low-level Paper Motion Control

Function Carriage return
ASCII [CR]

IPCL &%CR
EPOS 0DH
Description This command prints the contents of the print buffer (if any) and resets the
next character print position to the left margin. A line feed is not
performed unless autofeed was active. The left margin is defined by the
current print station, the print rotation direction, and the left margin
command.
Note: In single-line mode, the [CR] is used to terminate all lines. The
printer will go busy6 after the [CR] is received. The printer will not be
ready to accept data again until the previous data has printed.
Function Line feed

Description This command prints the contents of the buffer (if any) and advances the
paper one line at the current default line spacing. The next character print
position is not reset to the left margin unless auto-CR is active.
6 In one-line mode, the parallel port busy signal will occur as a result of receiving the [CR].
In serial mode, the busy indication will be delayed until the [CR] is processed by the input software.
Data sent to the printer after the [CR] will not be lost unless the printer is power cycled.
