4.4.3 Set Raster Bit Image Mode
GS v 0 +m +x 1 +x 2 +y1 +y2 +d1 dk [1D 76 30 +m +x 1 +x 2 +y1 +y2 (data)]
Specifies and prints RASTER bit image graphics.
Set Raster Bit Image Mode
+m Mode Vertical dot

( RICK)
0 (00 or 30 hex) Normal 203.2 dpi 203.2 dpi
1 (01 or 31 hex) Double Wide 203.2 dpi 101.6 dpi
2 (01 or 32 hex) Double high 101.6 dpi 203.2 dpi
3 (03 or 33 hex) Quadruple 203.2 dpi 203.2 dpi
Table 15 Set Raster Bit Image Mode
The number of data bytes which must be sent to complete this command = (x1+x2*256)*(y1+y2*256).
If +m is not one of the specified values, the rest of the ESC sequence is ignored and all information starting with +n1 is
treated as normal data.
The values of x1 and x2 select the number of data bytes (x1+x2*256) in the horizontal direction. The value of x1 can
be from 1 to 128 and the value of x2 must be 00hex so the maximum number of dots which can be specified is 1024
(128 bytes times 8 bits per byte). Any data specified and received which exceeds the printing width of the printer is
read in and then discarded.
The values of y1 and y2 select the number of dot rows (y1+y2*256) in the vertical direction. The value of y1 can be
from 0 to 255 and the value of y2 can be from 0 to 8 with the value of (y1+y2*256) being in the range of 1 through
4095.
??? does not compute? EPSON to specify
In standard mode, this command is effective only when there is no data in the print buffer. The starting point of the
printed image can be set by the HT (Horizontal Tab), ESC $ (Set absolute print position), ESC \ (Set relative print
position), or GS L (Set left margin) command if that position is a multiple of 8.
This command is not affected by print modes (character size, emphasized print, double strike, inverted print, underline,
reverse video, etc.). ESC a (Select justification) is effective on raster bit images. If the width of the printing area set by
GS L and GS W is less than the minimum width, the printing area is extended to the minimum width only on the line in
question. This minimum width is 1 dot in normal or double high mode and is 2 in double wide or quadruple mode.
Each data byte represents 8 horizontal dots to be printed with the MSB being to the left and the LSB being to the right.
. For each of the 8 bits within each data byte, a “1” represents a dot position to be printed and a “0” represents a dot
position not to be printed. The first x1+x2*256 data bytes are printed as the first raster line. The next x1+x2*256 data
bytes are printed as the second raster line. This sequence continues until all y1+y2*256 dot lines defined have been
printed. After printing the raster bit image, the printer returns to normal mode.
4.4.4 Status Commands
Three commands pertain to status transmission: DLE EOT +n, GS I +n, and GS a +n .
DLE EOT +n 10 04 +n
Real-time STATUS request
Status is transmitted immediately when this command is received without verifying that the host is ready to receive
data. This command is executed even if the printer is off-line, the receive buffer is full, or there is an error status with a
serial interface controller. With a parallel interface controller, this command cannot be executed when the printer is
BUSY but is executed when the printer is OFF-LINE or in an error state if MEMORY switch 1-3 is on. Status will be
transmitted even if a valid command string is received while receiving data as part of another command sequence
(such a part of a bit image pattern).
EPSON to answer ??? Check to see if the data is also then printed so the bit image pattern does not mess up
everything afterward.
This command must not be sent to the printer in the middle of any other multi-byte command sequence or this
command will be interpreted as the remaining part of the multi byte command.
Status Commands
n = Action
01 hex Transmit Printer status.
02 hex Transmit Offline status.
