Downloading the Character Data
You can start the character data at any unused memory address greater than
xA413. This example uses xB000.
Creating the Lookup Table Data
Before creating lookup table data, make note of the following memory
addresses.
• The valid download address range for the 249x printers is x800C to xFFFF.
• The ASCII character 0 lookup table entry addresses for the resident fonts
are:
— Draft (10 and 12 cpi) and Fast Draft (10 cpi) - x8011
— 10 cpi Letter Quality and Enhanced Letter Quality - x8912
— Proportional LQ and ELQ - x9213
— 12 cpi LQ and ELQ - x9B14
— Download character data can start at any address greater than xA413
