Appendix C Debugging Printer Output To effectively use the ESC commands to communicate with LabelWriter printers, you must understand the commands themselves. While DYMO cannot offer regular support for those wishing to communicate directly with the printer, there is a simple way to learn about and understand the commands - study what the DYMO printer drivers do with known data patterns. To do this: 1. Install the label printer on a Windows PC according to the instructions. Use the DYMO Label Software application to verify that the printer works. 2. From the Start menu, choose Settings, and then choose Printers. 3. Right-click on the LabelWriter icon, and then choose Properties from the menu. 4. Click on the Ports tab. In the list of ports, choose File. 5. Click OK. After performing these steps, whenever you print, you will be prompted to enter a file name and the output will be redirected to this file. Use the DYMO Label Software to print a variety of labels and examine the resulting files using a hex editor; use this manual to decrypt the data. © 2002-2008 Sanford, L.P. Page 27
