Therefore, the print data appears upside down when data is printed
normally. This command allows the data to be right-side up as it comes out
of the printer.
Remarks:
v When upside-down printing is enabled, the last line of data must be sent
to the print first.
v This command is valid only at the beginning of a print line.
Select character size for scalable fonts
This command is not supported for Models TI1 and TI2. This command is only
supported in the thermal station.
EIA-232 Syntax:
GS ! n or X'1D;21;n'
where:
n Defines the height and width of a character. The four least
significant bits (LSBs) specify the height and the four most
significant bits (MSBs) specify the width of the character. See
Table 20.
For example, if n=X'14' the scaled character will be twice the
defined width and five times the defined height.
Table 20. Width and height for scalable fonts
Four MSBs (in
hex)
Character Width Four LSBs (in
hex)
Character Height
0 As defined 0 As defined
1 2 × defined width 1 2 × defined height
2 3 × defined width 2 3 × defined height
3 4 × defined width 3 4 × defined height
4 5 × defined width 4 5 × defined height
5 6 × defined width 5 6 × defined height
6 7 × defined width 6 7 × defined height
7 8 × defined width 7 8 × defined height
Default:
n=00
Purpose:
To select the size of a character.
Remarks:
v This command is valid only in the thermal print station.
v Bits 3 and 8 of n are ignored.
v The Set Print Mode command (see “Set print mode” on page 129) can
also select the character height (double high and double wide). The last
command that is received is the effective command.
v Underline and overline is not supported when the height is scaled 8x
except on the TI8, TI9, TG8, and TG9.
v The bar for overline and underline is not magnified in thickness except
on the TI8, TI9, TG8, and TG9.
