• Except for HRI characters, this command is valid for all characters.
• If the setting of either the vertical enlargement rate or the horizontal enlargement
rate deviates from the definition range, this command is disregarded.
• In the Standard mode, the vertical direction indicates the paper feed direction and
the horizontal direction indicates the direction perpendicular to the paper feed di-
rection. Therefore, in specifying 90 degree rotated characters, the vertical-hori-
zontal relationship with respect to the characters is reversed.
• In the Page mode, the vertical direction indicates the vertical direction with respect
to the characters and the horizontal direction indicates the horizontal direction
with respect to the characters.
• If characters with a different vertical enlargement rate are mixed on the same line,
they are arranged along the base line.
• Horizontal and vertical double enlargement can also be specified and cleared by
ESC !, but the command that was processed last becomes the valid command.
• The initial value is “n = 0”.
(49) Specifying the character vertical absolute position in the
page mode (GS $ n1 n2)
Code: [1D] h + [24] h + n1 + n2
* (0 ≤ n1 ≤ FF)
(0 ≤ n2 ≤ FF) Data are expressed in Hex code.
In the Page mode, this command specifies the position in the characters' vertical direc-
tion of the data development start position as an absolute position with the starting
point as the reference. The position in the characters' vertical direction of the next data
development start position is a position [(n1 + n2 x 256) x basic calculation pitch] inch
from the starting point.
• This command is disregarded when a mode other than the Page mode is selected.
• An absolute position specification which exceeds the specified print area is disre-
garded.
• The data development start position does not shift in the characters' horizontal
direction.
• The starting point used as the reference is specified by ESC T.
• Movements from the starting point specified by ESC T are as follows.
(1) If “top left” or “bottom right” is specified as the starting point, the absolute
position in the paper feed direction (characters' vertical direction) is specified.
At this time, the vertical basic calculation pitch (y) is used.
(2) If “top right” or “bottom left” is specified as the starting point, the absolute
position in the direction perpendicular to the paper feed direction (characters'
vertical direction) is specified. At this time, the horizontal basic calculation
pitch (x) is used.
• The basic calculation pitch is set by GS P.
• If there is a fraction, interpolation is carried out at the mechanism's minimum pitch.
Remainders are cut off.
