Lexmark 248X, 249X manual 139, Send the following lookup table example to the printer

Creating the Lookup Table Data

Before downloading lookup table data or character data, make note of the fol- lowing memory addresses.

•The valid download address range for the 249x is x800C to xFFFF.

•The ASCII character 0 lookup table addresses for the resident fonts are:

—Draft (10 and 13 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 an address greater than xA413

In this example, the inverted exclamation mark, ASCII character 173, is replaced with the trademark symbol. Entry zero of the proportional table starts at x9213 and there are nine bytes per entry:

9 x 173 = 1557 = x615 (the offset into the table)

x615 + x9213 = x9828 (offset + character 0 lookup table address)

The address for the new lookup table entry for ASCII character 173 is x9828.

Downloading the Lookup Table Data

Send the following lookup table example to the printer:

<x

1B3D - download command prefix - lookup table data

0C00 - byte count (low byte first) - x000C,12

23- font id for 249x printers

2898 - start address in Lookup Table (low byte first) - x9828

A414 - start address of character data (high byte first) - xA414

1E- number of stored columns

29- number of printed columns - 1 (for last blank column)

2E74300002 - compression mask
