This driver was downloaded from the Panasonic FTP site in 11/99. All WWW sites refer you to the Win95 disk to install this printer.
Once installed, you may need to set the proper emulation on your printer. To do so, hold the LOAD/PARK button down when turning on the power. The printer will then show you the current emulation. This can be toggled using the FONT button. When set correctly, Save by pressing the LOAD/PARK button again.
I believe this file also includes Win3.1 drivers.
