Data Dump Mode

Look at the data dump printout shown in Step 2. By comparing the characters printed in the right column with the printout of hexadecimal codes, you can check what codes are being sent to the printer. If characters are printable, they appear as their true ASCII characters. Nonprintable codes, such as control codes, are represented by dots.

As an example of how to interpret a data dump printout, look at the first three hexadecimal codes on the third line of the printout sample (20 20 54). Each hexadecimal code (20) represents a space, while the hexadecimal code (54) represents the letter T. Check the third line of the right column and you will find the letter T preceded by two spaces.

The chart below interprets part of the first line of codes:
