Look at the sample data dump printout shown in Step 3. By reading the characters printed in the text field on the right side of the data dump printout or the printout of hexadecimal codes, you can check what codes are being sent to the printer. In the text field, printable characters appear as their true ASCII characters. Non-printable codes, such as control codes, are represented by dots.

For example, look at the first two hexadecimal codes on line 0006 of the printout sample (74 65). Code 74 represents the letter t; code 65 represents the letter e. Check the seventh line of thetextfieldontherightsideoftheprintoutandyouwillfind thelettertfollowedbythelettere.
