GS ( K <Function 49>

[Name]

Select the print density

[Format]

ASCII	GS	(	K	pL	pH	fn	m
Hex	1D	28	4B	02	00	31	m
Decimal	29	49	75	2	0	49	m

[Range]

(pL + pH × 256) = 2

fn = 49

m: different depending on the printers

[Default]

m = 0

[Description]

Selects the print density by m.

m	Function
128 – 255	Pale density
0	Standard density [setting value of GS ( E <Function 5> customize value (a = 5) ]
1 – 127	Strong density

Function

128 – 255

Pale density

Standard density [setting value of GS ( E <Function 5> customize value (a = 5) ]

1 – 127

Strong density

The specification of each print density differs, depending on the printer model. See model specific information.

[Notes]

When a Standard mode is selected, all the data in a line is printed in the same density.
When a Page mode is selected, all the data printed collectively by FF (in Page mode) or ESC FF is printed in the same density.

, TM-L90, TM-L90 LFC:

The following print densities are available.

m	Print density
250	Criterion density × 70%
251	Criterion density × 75%
252	Criterion density × 80%
253	Criterion density × 85%
254	Criterion density × 90%
255	Criterion density × 95%
0	Criterion density
1	Criterion density × 105%
2	Criterion density × 110%
3	Criterion density × 115%
4	Criterion density × 120%
5	Criterion density × 125%
6	Criterion density × 130%
7	Criterion density × 135%
8	Criterion density × 140%

A criterion density is the print density set by GS ( E <Function 5> (a = 5).

The print density actually set is as follows.

For Example: If (m = 4) is specified when 90% in a standard density is set, the print density becomes 110% [90% × 20%].

The print density can be only within the range of 70% to 130%. When it is set to exceed 130%, the print density becomes 70% or 130%.

For example: If (m= 6) is specified at 120% in a standard density, the print density becomes 130% though the calculated value is 150% [120% × 130%].
