(2) The maximum printable size of a bitmap image is 512 by 512 dots for standard mode.
can be extended up to 831 bits in the y direction (paper feed direction) if 831 bits are reserved for y of the print
area and the value of print direction "n" specified by ESC T is 1 or 3.
Mapping of print data in the print area
Print data is mapped in the print area as follows:
(1) The print area is set by ESCW.
before receiving an ESC W, the ESC W sets the left end (as viewed facing the printer) as the start point (x0, y0)
of the print area.
one edge running in the x (horizontal) direction by dx pitch (inclusive of the start point), and the other running
in the y (vertical) direction by dy pitch.
print area.)
(2) With a print area defined by ESC W and a print direction specified by ESC T, when the printer receives print
data, the print data is mapped in the print area where point A (see the figure "Mapping Position for Character
Data") is used as the initial value of the start point. If the print data consists of characters, this start point serves
as the baseline.
If the print data is a downloaded bitmap image or a bar code, the print data is mapped with its lower-left point
"B" aligned to the baseline (see the figure "Mapping Positions for Print Data").
HRI characters of a bar code, however, the section above the standard character height will not be printed.
(3) If print data (or the space to the right of a character) extends beyond the print area before command that
involves a line feed (for example, LF or ESC J command) is received, a line feed is automatically executed, so
that the mapping position of the print data is moved one line.
beginning of the line. In this case, the line feed width is as defined by a command such as ESC 2 or ESC 3.
(4) By default, the line feed width is 1/6 inch, which is equivalent to 30 dots.
includes a vertically doubled character or taller, a downloaded bitmap image extending two or more lines, or a
bar code taller than the character height, the data, therefore, falls short of the line feed width, causing the upper
dots of the character to overlap the print data of the current line.
In the following example the line feed width for the first line should equal at least 27 dots (see the figure
"Mapping Position for a Downloaded Bitmap Image").
When the printer has finished all of the print and paper feed actions specified
The print area is a rectangle defined by two edges extending from the start point (x0, y0):
