Each row has a left and right row indicator with a data region between. The left-most character in the top row of the
data region is the total number of characters in the data region, excluding error correction characters. Characters
within the data region are designed to be read from left to right, starting on the top row, immediately after the length-
defining character. The maximum characters in the data region are 928.

Page mode
Page mode is one of two modes that the A776 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. Once the printer receives the (0 × 0C) command,
it prints the page and returns the printer to standard mode.

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.
