Define CR (Carriage Return) Code
The DEFINE CR CODE option controls the action of the printer when it receives
a Carriage Return code (hex 0D) from the host computer. If this feature is
enabled, each time the printer receives a Carriage Return, it inserts an additional
Line Feed code (hex 0D) into the data stream. Do not use this feature if the host
computer sends Line Feeds to the printer.
Auto LF
The AUTO LINE FEED option defines the printer actions when print data is
received past the forms width setting.
DISABLE discards any data past the forms width.
ENABLE performs an automatic carriage return and line feed when data
is received past the forms width.
Define LF Code
The DEFINE LF CODE option controls the action of the printer when it receives a
Line Feed code (hex 0A) from the host computer. If this feature is enabled, each
time the printer receives a Line Feed, it inserts an additional Carriage Return
code (hex 0D) into the data stream. This feature can be used in most
installations, but it is required if the host computer does not send Carriage
Returns to the printer.
LF = CR + LF adds an extra Carriage Return with each Line Feed.
LF = LF does not add a Carriage Return with a Line Feed.
