DMP 205  (260-2904)         Using Control Codes       Faxback Doc. # 5730

The following example uses BASIC'S CHR$() function to send a multiple
code sequence to the printer.

Set up the printer and enter BASIC in the normal way.  then type and
run the following program:

10 LPRINT "HALF LINE; CHR$(27);"J";CHR$(15);'
   Performs 15/180 inch line feed
20 LPRINT "FEEDING"

Roll the paper forward and look at the result.  the word FEEDING is
printed just below HALF LINE with half line spacing, because the codes
CHR$(27);"J";CHR$(15) tell the printer to change the forward line feed
to 15/180 inch (1/12 inch), which is half of the normal distance.

NOTE:  Results vary, depending on the LF or CR function switch setting
       in your printer.  If you activated the LF command, this could
       also cause a difference result.

The "Control Sequence Summary" table that follow show the control code
sequences grouped according to function.  These tables list the name
and mnemonic for each code sequence.  Examples of some mnemonics are:

--------------------------------------------------------------------------
MNEMONIC                               DEFINITION
--------------------------------------------------------------------------
n                                      indicates a number
NUL                                    null code
HT                                     horizontal tab
LF                                     line feed
VT                                     vertical tab
FF                                     form feed
CR                                     carriage return
SO                                     shift out
SI                                     shift in
DC                                     device control code
CAN                                    cancel
ESC                                    escape
SP                                     space

Where a character appears by itself, that character, or its appropriate
code, is a part of the control code sequence.

SELECTING A FONT SET

The following command selects an LQ font when the LQ mode is selected
by the ESC x n command

10 LPRINT CHR$(27);"x";CHR$(1);:'Selects the LQ mode
20 LPRINT CHR$(27);"k";CHR$(2);:'Selects Courier Font
30 LPRINT "Courier Font Printing ";
40 LPRINT CHR$(27);"k";CHR$(1);:'Selects Sans Serif Font
50 LPRINT "Sans Serif Font Printing";
