Star Micronics LC24-20 user manual Copy character set from ROM into RAM

nz5through n?9are compression mask bits. Data compression allows the efficient use of memory in storing downloaded characters pro- viding space for more characters than would be available without compression. The printer repeats the previous dot column in the current column when the current column compression mask bit is set to 1.

It is necessary to define all of Index Table data before the Dot Pattern data to download many characters.

dl, d2, ... d.~is the Dot Pattern data being downloaded.

Each data byte indicates eight vertical dots, with the most significant bit being the top dot, and the least significant bit being the bottom dot.
