Character Library Map

Character Number Map

Describes the location of the selected character library: ROM or RAM. Character sets and character maps selected from the configuration menu are stored in ROM. Mapped characters originate in ROM, so their source is ROM. Download characters are downloaded directly to RAM, so their source is RAM.

A character library is a defined group of printable characters stored in the printer. This map shows which library is currently active for each data byte value between 0 and 255.

Each character in a character library is numbered. The character number map specifies which characters are currently selected for each data byte value between 0 and 255.
