A
Dither matrix data
B
a.Dither matrix size
Specifies the size of dither matrix to be downloaded. This scanner supports 1¥1 to 32¥32. If any other value is specified, this scanner returns the following error information:
f Status: B©00001 (CHECK CONDITION)
f Sense key: X©5 (ILLEGAL REQUEST)
b.Dither matrix data
Specifies the values of dither matrix in the range of 0 to 255, starting from the upper> left corner. (Value 0 represents the darkest, with 255 the brightest.)
The number of data vlaues is the sum of the X> and Y>direction elements as specified in the matrix size fields. If the number of data values differs from that sum, this scanner returns the following error information:
f Status: B©00001 (CHECK CONDITION)
f Sense key: X©5 (ILLEGAL REQUEST)
