the specified printing area in memory, and the position in memory for the next print data is
shifted by one line.
The ESC L command puts the printer into page mode, and all commands received
thereafter are processed in page mode. Executing an ESC FF command prints the
received data collectively, and executing an FF command restores the printer to standard
mode after the received data is printed collectively. Executing an ESC S command
restores the printer to standard mode without printing the received data in page mode; the
received data is cleared from memory instead.
Shifting Between Standard Mode and Page Mode
B.2 Setting Values in Standard and Page Modes
1) The available commands and parameters are the same for both standard and page
modes. However, these values can be set independently in each mode for the ESC SP,
ESC 2, ESC 3, and FS S commands. For these commands, different settings can be
stored for each mode.
B.3 Formatting of Print Data in the Printable Area
Formatting of print data in the printable area is performed as follows:
1) The printable area is set using ESC W. If all printing and feeding are complete before
the printer receives the ESC W command, the left side (as you face the printer) is taken as
the origin (x0, y0) of the printable area. The printable rectangular area is defined by the
length (dx dots) extending from and including the origin (x0, y0) in the x direction
(perpendicular to the paper feed direction), and by the length (dy dots) in the y direction
(paper feed direction). (If the ESC W command is not used, the printable area remains the
default value.)
2) When the printer receives print data after ESC W sets the printable area and ESC T
sets the printing direction, the print data is formatted within the printable area so that point
A in Figure B.2 is at the beginning of the printable area as a default value. (When a
character is printed, point A is the baseline.)
Print data containing downloaded bit images or bar codes is formatted so that the bottom
point of the left side of the image data (point B in Figure B.3) is aligned with the baseline.
However, any Human Readable Interpretation (HRI) characters are printed under the
baseline. At the points labeled Point B, if characters (such as double-height characters)
higher than normal size characters or downloaded bit image characters are received, any
part of the character higher than the normal-size character is not printed.
