Kyocera DP-1800 Command Reference Manual page 251

The following examples produce invalid raster data lines:
Wrong:
0,; Count cannot be 0.
1; Use 1,; for a blank line.
2, 1, 1, 1; Too many data values.
2, -1, -1; Negative values are not allowed.
2, 1
, 1; Carriage return before comma.
An invalid raster data line is not printed, and invalidates all raster lines that follow.
Again, the following example demonstrates how to create the raster graphic on the
previous page.
!R! STR 75; RVRD;
2;A|0;
2;GG0;
2;^S;
2;˜{>>;
2;^S;
2;GG0;
2;A|0;
ENDR;
PAGE; EXIT;
The value 2 in each raster data line indicates the number of data which follows. The
subsequent data can be obtained by following the same procedure as explained in
Defining Fill Patterns in Chapter 2 of the Technical Reference manual.
