Image Data; Image Look-Up Table Id Parameter - Ricoh MP 6002 User Manual

Offset Range
2
X'01'
X'08'
If 1 is specified, the image is binary, with 1-bit representing black pixels and 0- bit representing pixels
unchanged in the page map. If the image is uncompressed, each raster scan in the image data must be
padded so that it is an integral number of bytes.
If 8 is specified, the image is gray scale. Each image byte is considered to be a value 0 to 255, where 0
is maximum black, 255 is no black at all, and the values in between are shades of gray.
The printer implements 8 bit per pixel images by halftoning. Halftoning significantly degrades image
detail. For that reason, resolutions of gray scale data greater than 120 pixels per inch are not
recommended except for draft printing purposes.
If 8 is specified, the Image Compression, if specified with the Image Encoding command, must be
uncompressed. This error is detected when the first Image Data command is received.
