Page mode
Page mode is one of two modes that the A799 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 80mm paper. If the printer supports 82.5mm paper, the dot spacing is the same
but there are 640 printable dots rather than 576 printable dots on 80mm paper.

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.

Collectively prints all buffered data in the printing area.
After printing, the printer does not clear the buffered data and sets values for select print direction in page mode (1B 54 n)
and set print area in page mode (1B 57 …), and sets the position for buffering character data.
