Define CR Code (Carriage Return)

This parameter forces the printer to insert an automatic Line Feed code into
the data stream whenever a Carriage Return code occurs. This is to be used
only if the host computer does not send Line Feeds to the printer.
CR = CR. The default. Does NOT perform a line feed. The next print
position will be print position 1 of the current line.
CR = CR + LF. Performs an automatic line feed. The next print
position will be print position 1 of the next line.

Define LF Code (Line Feed)

This parameter forces the printer to insert an automatic Carriage Return code
into the data stream whenever a Line Feed code occurs. This can be used in
most installations, but it is required if the host computer does not send
Carriage Returns to the printer.
LF = LF. The default. Does not perform an automatic carriage return.
The next print position will be the current print position of the next line.
LF = CR + LF. Performs an automatic carriage return. The next print
position will be print position 1 of the next line.

Autowrap

This parameter determines if text will wrap to the next line when the line of
text exceeds the right margin.
Disable. The default. Truncates the text beyond the right margin until a
CR or CR+LF is received.
Enable. Automatically inserts a CR+LF after a full print line.
