Define Lf Code; Printer Select; 20 Cpi Condensed - IBM 6400 Setup Manual

Define LF Code

The DEFINE LF CODE (Define Line Feed Code) option controls the action
of the printer when it receives a Line Feed code (ØA hex) from the host
computer. If this feature is enabled, each time the printer receives a Line
Feed, it inserts an additional Carriage Return code (ØD hex) 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 = LF (the default) does not add a Carriage Return with a Line Feed.
LF = CR + LF adds an extra Carriage Return with each Line Feed.

Printer Select

This option determines if the ASCII DC1 and DC3 control codes can be used
to disable and enable the printer.
DISABLE (the default) ignores the DC1 and DC3 control codes.
ENABLE disables the printer when a DC1 control code is received, and
enables the printer when a DC3 control code is received.

20 CPI Condensed

When the 20 CPI CONDENSED (20 Characters Per Inch Condensed) option
is enabled, and compressed print is chosen by the host computer, the printer
prints characters that are about 60 percent of the width of normal characters.
For example, a 12 CPI Draft font will compress to 20 CPI. This is helpful for
applications where you need to print the maximum amount of information on
a page.
ENABLE (the default) prints narrow characters when compressed print
is chosen by the host computer.
DISABLE will not compress the character widths, even if condensed
print is chosen by the host.
