Page mode
Page mode is one of two modes that the A795 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.
Print and return to standard mode

Decimal 12
When printing is completed, values for select print
direction in page mode (1B 54n) and set print area in page
mode (1B 57 n1, n2, …n8) and the position for buffering
character data are set. Buffered data is not deleted from the
printer.
The processed data is printed and the printer returns to
standard mode. The developed data is deleted after being
printed. For more information see page mode in this
document.

and sets the position for buffering character data.
Exceptions
