2-82 PCL Adaptive Compression Adaptive compression allows the combined use of compression methods 0 through 3 (Uncoded, Run-Length Encoded, TIFF, and Delta Row). It also allows the printing of empty rows (all zeros) or duplicate rows. • The Transfer Raster Data command size includes all rows (scan lines). • Scan Mode and SizeH,L are three-byte primary control strings: CountH and CountL.
