How to Use the Charts

To determine the hexadecimal number that prints a particular character, find the character in one of the tables; then look at the top of its column and at the beginning of its row. The number at the top of the column is the first digit of the characters hex code, and the number at the beginning of the row is the second digit of the hex code.

For example, find the capital Z in the Epson Draft chart on the next page. At the top of its column is 5 and at the beginning of its row is A. Therefore the hex code for a capital Z is 5A.

Converting hexadecimal numbers to decimal numbers

If you prefer to use decimal numbers instead of hexadecimal numbers, you can convert them with the chart below. Just read down in the column for the first digit of the hex number and across in the row for the second digit. Where the two intersect is the decimal number that corresponds to your hex number. For example, to find the decimal equivalent of hex 5A, look where column 5 intersects with row A. There you will find decimal 90.
