ESC X m n1 n2 (Select Pitch and Point Size)

C X m n1 n2 is the command for selecting pitch and point size where m, n1 and

n2 are variables. The variable "m" is used to select the pitch which is the character

spacing. The variable "n1" selects the point size and the variable "n2", at this time,

will always be 0 (zero). The variables "m" and "n1" are explained below.

The values used for 'm' are 0,1,18,21,24,30,36,42,48,60, and 72. If "0" is

used as the value for "m", there will be no change in pitch. If "1" is used as the

value for "m", the character pitch will be proportional spacing. To determine the

character pitch for all other values of "m", divide 360 by "m". For example, if m=60

then 360 divided by 60 equals 6 and the character pitch is 6 characters per inch. If

m=30, the character pitch is 12 characters per inch.

For the Roman and Sans Serif fonts, the values used for "n1" are 0,16,20,21,24,

28,32,36,40,42,44,48,52,56,60 and 84. For all other fonts, the values used for

"n1" are 0,21, and 42. The actual point size that will print is n1 divided by 2. For

example, if n1=20, the point size is 10. If n1=48, the point size is 24. NOTE:

When selecting a point size larger than 24 (the value for n1 is greater than 48)

select proportional spacing (m=1) for the character pitch.

In the Basic programming language, the command would look like this.

LPRlNT CHR$(27);"X";CHR$(1);CHR$(48);CHR$(0);"This is 24 point proportional

spaced"

Chr$(27) is ESC, chr$(1) selects proportional spacing, chr$(48) selects 24 point

character size. At this time, n2 is always zero (0).
