Page Formatting Control Codes
These control codes change the formatting of the page:
• The page length (form length) and margin settings define the printable area
on the page, and must conform to the actual size of the paper used in the
printer.
• The line spacing control codes set the amount of space from one line to the
next, for line feeds. The page length, vertical tab, and skip over perforation
functions are dependent on the line spacing function.
