Using Data Dump Mode 4. To turn off the data dump mode and stop printing, press ON LINE to set the printer off line. (If you press ON LINE while a page is being printed, the green ON LINE light flashes until the page is ejected and the printer goes off line.) To exit the data dump mode, turn off the printer or hold down the RESET button until INITIALIZE appears on the display. 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 0004 of the printout sample (73 20). Code 73 represents the letter s; code 20 represents a space. Check the fifth line of the text field on the right side of the printout and you will find the letter s followed by a space. The chart below interprets part of the first line of codes: Hex codes 1B 52 10 1B4345 1B6B00 1B 70 00 Command ESC R 10 ESC C ESC k ESC p Function Select USA (symbol set) character set Set page length Select typeface Turn proportional mode on/off Troubleshooting 7-49
