Upgrading the Firmware
To upgrade the printer firmware you will need the following.
Once you have downloaded the upgrade files, launch the ESim
Config Tool and follow the instructions to upgrade the firmware.
• An upgrade file (.ufz). Download new firmware files from
www.intermec.com.
• A host computer running Microsoft Windows with a USB,
parallel, or serial RS-232 connection. Intermec recommends a
parallel or USB connection.
• The Intermec ESim Config Tool for the PF8 is on the
PrinterCompanion CD or can be downloaded from
www.intermec.com. Use the ESim Config Tool to install a
firmware upgrade file on the printer, download new fonts,
and manage printer memory. It supports seven languages and
comes with comprehensive online help.
