EFP9800 ESC/POS Commands
3255 4073– 002 6– 71
Command Settings in Both Modes
The command settings are treated the same in page mode as they are in
standard mode. However, there are some differences:
•
The settings for the following commands are set independently in both
modes:
Set Right-Side Character Spacing (1B 20)
Set Line Spacing to Default
Spacing (1B 32)
Set Line Spacing (1B 33)
Set/Cancel Uni-Directional
Printing (1B 55)
•
Horizontal tabs are treated somewhat differently in both modes. In
standard mode, if the command, Horizontal Tabs: Skip to Next Tab Stop
(09), is received when there are no more tab stops before the end of a line,
the print starting position will be set to the beginning of the next line. In
other words, a line feed will be performed. However, under the same
circumstances in page mode, the print starting position will be set to the
end of the current line. Any subsequent character received will cause an
auto-line feed to be performed.
•
The Select Bit Image Mode command (1B 2A) can print up to 704 full dots
in the y direction in page mode, as opposed to only 200 full dots (400 half
dots) in standard mode under the following circumstances: the printable
dots in the y direction are set to 704 for the Set Printing Area in Page Mode
command (1B 57), and the printing direction is set to 1 or 3 for the Select
Print Direction in Page Mode command (1B 54).
Processing the Data in the Page
The following information describes how to process the data in page mode:
•
Use the Set Printing Area in Page Mode command (1B 57) to set the “ page”
or printing area. For more information, see “ Set Printing Area in Page
Mode.”
The illustration shows a sample of the “ page” area and its origin points (x0,
y0). The area of the page is defined by dx, including the origin and extends
in the x direction, and by dy in the y direction.
