Page Mode Commands
Page Mode is one of two modes that the A794 printer uses to operate. Standard Mode is
typical of how most printers operate by printing data as it is received and feeding paper
as the various paper feed commands are received. Page Mode is different in that it
processes or prepares the data as a “page” in memory before it prints it. Think of this as
a virtual page. The page can be any area within certain parameters that you define. The
page is printed using either the FF (0C) or the ESC FF (1B 0C) command.
The Select Page Mode command (1B 4C) puts the printer into Page Mode. Any
commands that are received are interpreted as Page Mode commands. Several
commands react differently when in Standard Mode and Page Mode. The descriptions
of these individual commands in this chapter indicate the differences in how they
operate in the two modes.
These commands describe the operation for 80 mm paper. If the printer supports 82.5
mm paper, the dot spacing is the same but there are 640 printable dots rather than 576
printable dots on 80 mm paper.

The processed data is printed and the printer returns to Standard Mode. The developed
