There are two basic modes of operation: HP PCL mode and Epson Emulation mode.
- HP PCL mode would be used if there were a driver available for the HP RuggedWriter printer in the program you are using. To place the HP RuggedWriter in HP PCL mode, set the dipswitch B1 in the down position.
- Epson Emulation mode (Alternate mode) would be used if there were not an HP RuggedWriter driver available. In this mode, the HP RuggedWriter can emulate an Epson LQ 800 or an Epson LQ 1000. To place the HP RuggedWriter in Epson Emulation mode, set the dipswitch B1 in the up position.
The resident fonts (internal fonts) are used to set the printing format for the HP RuggedWriter printer.
