In the MICROLINE Standard emulation, margins for these commands are measured in units of
1/120" from the leftmost printing position.

represent a three-digit ASCII number for the value of the location for the left

represent a four-digit ASCII number for the value of the location for the
right margin. If the value you wish to assign is less than four digits, use zeros for the first digit(s).
The right margin must be at least 60 units greater than the left margin. If no left margin has
been set, the minimum value for the right margin is 60 units.
You must set the right margin before sending any data for the line on which it is to take effect.
The Maximum Margin Values table below lists the widest allowable margins.

For example, suppose you want to set one-inch margins on a standard 8-1/2" page. The left
margin will be 120/120" from the leftmost position, so the command to set it is:
LPRINT CHR$(27);"%C";"120"
The right margin is 7-1/2", or 900/120" from the leftmost position, so the command to set it is:
LPRINT CHR$(27);"%R";"0900"
