Raster Command Reference Explanation of "TIFF compression mode" With compression, the data for the "raster graphics transfer" command is based on 56 bytes (TD-2020/2120N/2125N/2125NWB) or 84 bytes (TD-2030A/2130N/2135N/2135NWB) of the total number of pins (TD-2020/2120N/2125N/2125NWB: 448 and TD-2030A/2130N/2135N/2135NWB: 672). 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 104 bytes when it is expanded by the printer, regardless of the tape width.

Explanation of “TIFF compression mode”
With compression, the
data for the “raster graphics transfer” command is based on 56 bytes
(TD-2020/2120N/2125N/2125NWB) or 84 bytes (TD-2030A/2130N/2135N/2135NWB) of the total number of
pins (TD-2020/2120N/2125N/2125NWB: 448 and TD-2030A/2130N/2135N/2135NWB: 672). 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 104 bytes when it is expanded by the printer, regardless of the tape width.
