IBM Personal Computer AT Manual To Operations page 208

If the initialize function is set Off by ESC?,
all control codes are cleared and the printer
is set to the values set by the DIP switches.
(See "ESC?" for more details about the
initialize function.)
LPRINT CHR$(24);
CR Carriage Return
Causes the printer to print the data that
follows CR beginning at the left margin.
No line-feed operation takes place unless
DIP Switch 4 is On or ESC 5 (automatic
line-feed) has been sent.
Note: IBM Personal Computer BASIC
(and many other programs)
automatically sends LF (line feed) with
CR. If you do not want LF sent after
CR, use ASCII decimal value 141 from
Character Set 1 instead of ASCII
decimal value 13.
LPRINT CHR$(13);
DCl Select Printer
Sets the printer to accept data from the
system unit.
LPRINT CHR$(17);
DC2 10 Characters per Inch Print
Selects character spacing of 10 characters
per inch.
LPRINT CHR$(18);
