2.Names the graphic(this name is used to recall it into a label).
3.Defines the size of the graphic.
4.Downloads the hexadecimal string to the printer.
Format: ~DGd:o,x,t,w,data
Parameters:
d = destination device to store image
Accepted Values: a non-volatile RAM device
Default Value: R: (DRAM)
o = image name
Accepted Values: 1 to 8 alphanumeric characters
Default Value: If no name is entered, UNKNOWN is used.
x = filename extension
Fixed:. GRF
f = total number of bytes in graphic
Refer to the formula on the following page.
w = number of bytes per row
Refer to the formula on the following page.
data = ASCII hexadecimal string defining image
The data string defines the image and is an ASCII hexadecimal representation of the
image. Each character represents a horizontal nibble of four dots.
The t parameter can be determined by using the following formula:
where x is the width of the graphic in millimeters, y is the height of the graphic in millimeters and
dots/mm is the print density of the printer being programmed.
For example, to determine the correct t parameter for a graphic 8mm wide, 16mm high and a print
density of 8 dots/mm, the formula works this way:
Raise any portion of a byte to the next whole byte.
The w parameter (the width in terms of bytes per row) can be determined by using the following
