3.12.3Formatting 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 3.12.2 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 3.12.3) 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
3)If the print data (including the space to the right of a character) exceeds the printable area before the printer receives a command (e.g., LF or ESC J) that includes line feeding, a line feed is executed automatically within the printable area. The print position, therefore, moves to the beginning of the next line. The line feed amount depends on the values set by commands (such as ESC 2 and ESC 3).
4)The default value of the line spacing is set to 4.23 mm {1/6″ } and corresponds to 30 dots in the vertical direction. If print data for the next line contains extended characters that are higher than
