Explanation
(1) After this command is executed, the next print starting position is the beginning of a
line.
(2) There is no impact upon the line feed length specified by the 30-dot Line Feed
Length Set Command ([ESC] 2) or Minimum Dots for Line Feed Length Set
Command ([ESC] 3).
(3) Fractions are rounded up, if any.
(4) In standard mode, dots in the vertical direction (y) are used.
(5) In page mode, the printer operation varies depending on the starting position, as
follows:
1
If “top left” or “bottom right” is selected as the starting position by the Page Mode
Print Direction Set Command ([ESC] T), the print position will be shifted in the
paper feed direction (vertical direction of a character). In this case, dots in the
vertical direction (y) are used.
2
If “top right” or “bottom left” is selected as the starting position by the Page Mode
Print Direction Set Command ([ESC] T), the print position will be shifted in the
direction perpendicular to the paper feed direction (vertical direction of a
character). In this case, dots in the horizontal direction (x) are used.
(6) The value in the table below must be applied if the specified feed length exceeds it.
B-EP2DL-GHxx (203 dpi)
999 mm
B-EP4DL-GHxx (203 dpi)
999 mm
(7) If the value set in the parameter of this command is smaller than the feed length of a
character, printing will be performed with one character superimposed on another.
Therefore, care must be taken to select the feed length.
