Explanation of “TIFF compression mode”
With compression, the data for the “raster graphics transfer” command is based on 16 bytes
(PT-H500/P700/E500) of the total number of pins (PT-H500/P700/E500: 128). As shown below, with no
compression, the sum of the number of offset pins and the number of pins within the print area is the byte data.
However, with compression, the number of unused pins is also added to the data. In other words, with
compression, this becomes 16 bytes when it is expanded by the printer, regardless of the tape width.
