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.

It refers to a standard for compression as well as the library that implements the standard. This same algorithm is used by more widely known compression utilities such as PKZIP and GZIP. An encoder determines how to break the data into blocks and finds the best compression method to use for each block. The encoder creates a dictionary containing different characters in a set of data. Short strings of bits represent more commonly occurring characters, and long strings of bits represent less frequently used characters. Repeated patterns in a string of characters are identified and stored, so the string doesn't have to be stored multiple times. A three-bit zlib header is added to the beginning of a block to describe the type of compression used and indicates whether the block is a final block. Other information in the header includes checksums, compression algorithm used, and the level of compression. In compression all checksums are set to zero and in decompression the checksums are ignored. The memory required for zlib compression and decompression is independent of the size of the data to be compressed or decompressed. The number 999 does not conflict with other compression types, so it is used to represent zlib compression. See "Raster Compression Mode" in this section for more information. Page 1-36 SATO D512 PCL Programming Manual Unit 1: PCL Emulation GROUP 3 AND GROUP 4 RASTER COMPRESSION Since Group 4 images do not use line endings, the width of the image must be specified using the Raster Width command (ESC*r#S). The compressed image data is sent to the printer using the Transfer Raster Data command (ESC*b#W). The maximum number of bytes that can be sent using the Transfer Raster Data command is 32K bytes. Images larger than 32K bytes must be broken up and sent using multiple commands. It does not matter where the image is broken, or how many Transfer Raster Data commands are used. [. . . ] (RS = record separator, ASCII 30, hexadecimal 1D;yy is a two digit year). An optional secondary message follow the class of service for modes 2 and 3. For modes 4, 5, and 6 the message follows the number-of-labels field.

Mode 3, separated with commas: &y48W1, 1, ABC01, 840, 001, This is the secondary message. ESC ESC Mode 3, separated with GS and commas plus optional ANSI Message Header (yy=99): ESC&y45W1, 1, [)RS01GS99ABC01GS840GS022GSsecondary message Mode 4, separated with commas: ESC&y28W1, 1, Here is a mode 4 message HUMAN-READABLE TEXT Because two-dimensional bar codes are capable of encoding thousands of characters, humanreadable interpretation of the data may not be practical.
