For example, to print in the proportional mode the code format is the following: ASCII: ESC n Decimal: 27 1:2 n Hexadecimal: 1B 70 n In this case n can be either 1 (on) or 0 (off), to begin or end proportional printing. To turn on proportional printing from BASIC, use the following command: LPRINT CHR$(27);"p";CHR$(l) For the following commands that use only 0 or 1 for the variable, either the ASCII codes 0 and 1 or the ASCII characters 0 and 1 can be used: ESC U, ESC x, ESC p, ESC W, ESC S, ESC -, ESC %, and ESC w.
