The final number "n" in this code is any number between 1 and 11. This 
allows up to 11 dot spaces to be inserted between each character. 
Normally, a printer puts three dot spaces between each character. If 
character spacing is to be used with proportional spacing, proportional 
spacing has to be specified.
This command increases spacing between characters in multiples of:
1/120 inch (0.21 mm, 10 CPI)
1/144 inch (0.18 mm, 12 CPI),
1/180 inch (0.14 mm, 15 CPI)
1/206 inch (0.12 mm, 17.1 CPI)
1/240 inch (0.11 mm, 20 CPI).
The maximum variable number is 11, so the maximum possible space 
between characters is:
14/120 inch (2.96 mm) at 10 CPI
14/144 inch (2.47 mm) at 12 CPI
After setting the spacing, it stays in effect until the printer is turned off, the 
setting is changed, or standard spacing is selected.
CHARACTER SETS
In IBM emulation mode, the printer allows selection between two IBM 
character sets and numerous international character sets.
IBM Character Sets
IBM Character Set 1 repeats many of the non-printable commands (such 
as ESC and NUL) at the higher end of the ASCII scale, at decimal 
locations 128 through 155. The ESC command, for example, can be given 
as either decimal value CHR$(27) or CHR$(155). In IBM Character Set 2, 
the high ASCII values are reserved for characters used in foreign 
languages. Both these character sets have line graphics characters and 
mathematical symbols at decimal locations 160 through 255 on the ASCII 
chart. IBM Character Set 2 also includes special characters in decimal 
locations 3 through 6: a heart, diamond, club and spade. The section on 
non-ASCII characters explains how to print these special characters. 
Appendix B shows the two IBM character sets.
