Star Micronics 4 manual Byte Meaning

to describe and map your character. Sixteen bytes are needed for the description;the bit-map takes as many bytes as you’ve put into each charactercell—perhapstwo or tie hundredbytes.

As withthe fontheader,eachbytein the characterdescriptionis a number, sent as the symbol at that positionin the ASCII table. Codingcharacter descriptionsis tricky too, so again we recommend you ask your Star Micronicsdealer for help. The table below shows what the bytes in the characterdescriptionmean:
