<Function 48> GS ( L pL pH m f n
[Format] 1DH, 28H, 4CH, pL, pH, m, fn,
[Valid limits] (pL+pH×256)=2 (pL=2, pH=0)
m=48
fn=0, 48
[Function] (1) It transmits the total capacity of the NV graphics area in byte counts.
Hex Decimal Data number
Header 37H 55 1 byte
Identification 30H 48 1 byte
Data 30H ~ 39H 48 ~57 1~8 byte
N U L 00H 0 1 byte
(2) The total capacity is expressed in decimal, changes to character code and transmits from the top
digit.
The data number becomes a changeable length.
It is possible to designate the total definition area from one of the [384K, 448K, 512K,
576K]bytes from GS (E. The initial value is 384 byte.
<Function 50> GS ( L pL pH m f n
[Format] 1DH, 28H, 4CH, pL, pH, m, fn
[Valid limits] (pL+pH×256)=2 (pL=2, pH=0)
m=48
fn=2, 50
[Function] (1) The process of <Function 112> prints the print buffer stored in the graphics data.
(2) It executes the paper-feed equivalent to the dot count in the Y-direction graphics stored in the printer
buffer.
<Function 51> GS ( L pL pH m fn
[Format] 1DH, 28H, 4CH, pL, pH, m, fn,
[Valid limits] (pL+pH×256)=2 (pL=2, pH=0)
m=48
fn=3, 51
[Function] (1) The NV graphics area transmits the remaining quantity (byte count of the unused area).
Hex Decimal Data number
Header 37H 55 1 byte
Identification 31H 49 1 byte
Data 30H ~ 39H 48~57 1~8 bytes
N U L 00H 0 1 byte
(2) The remaining capacity quantity is expressed in decimal, changes to character code and transmits
from the top digit.
The data number becomes a changeable length.
