Operating System: Windows 95 (Note: might work with other versions of this os.)
To install this driver, please unzip epl5500w.zip then unzip sw038_1.zip & sw038_2.zip to two individual diskettes and install driver from the diskettes.
I have personally used it on Windows 98SE. The printer is autodetected by Win98 and asks for the driver.
It installs the driver in two stages. First on boot up and then continues after boot up is complete.
