IBM TM7, TI5, TF7, TG5 manual Select Character Size for Scalable Fonts

The Set Print Mode command (see “Set Print Mode” on page 125) can also select the character height (double high and double wide). The last command that is received is the effective command.

updated March 18, 2002

Purpose:

When the printer is wall-mounted, the front of the printer points up. 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:

vWhen upside-down printing is enabled, the last line of data must be sent to the print first.

vThis command is valid only at the beginning of a print line.

Select Character Size for Scalable Fonts

This command is supported only for the thermal station.

RS-232 Syntax:

GS ! n or X'1D;21;n'

where:

nDefines 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 17.

For example, if n=X'14' the scaled character will be twice the defined width and five times the defined height.

Table 17. Width and Height for Scalable Fonts

Four MSBs (in	Character Width	Four LSBs (in	Character Height
hex)		hex)
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:

vThis command is valid only in the thermal print station.

vBits 3 and 8 of n are ignored.
