This technical reference manual is intended to help you get the most out of each of the emulation modes supported by your HL-Series printer. It is divided into nine sections - this introductory section and one section for each of the emulation modes. Each emulation mode section describes the software commands (the escape sequences and control codes) that you can use to make the printer perform each of its available functions. Some example programs are included to give you useful ideas.

This manual is for our PCL models. For the differences between each model, see the Appendix "Model Comparison."

• "PCL6" includes both "PCLXL" and "PCL5e".
• As for "PCL5e", it is described in "chapter 2 PCL" of this manual.
• As for "PCLXL", it is mainly used with Windows driver, and its command is structured by binary code. Therefore, it is not described in this manual.
• For basic set-up information, such as how to connect the printer to your computer, look in the User's guide.
• The User's guide also describes the printers control panel and how you can set various options using the keys.
