Chapter 4 Specifying Control Information

This chapter describes how you should specify page-control and
cursor-movement commands and data for your printer. Page-control commands
are sent to the printer by the Microsoft Windows Universal Printer Driver
to begin a document, to begin a page, to end a document, to end a page, to
cancel a print job, and so on. Cursor-movement commands are sent to the
printer to move the cursor (which is sometimes called the print head)
horizontally across the page, vertically down (and sometimes up) the page,
and so on.
