This package contains the demo-version of JetPilot, a printer driver for HP-Deskjet and HP-Laserjet type printers. All printer options are fully supported, with the exception that the word Demo is printed diagonally over each page. With the purchase of the driver the customer will get a registration code which he can apply to the driver using the registration application. This will simply disable the demo-mode. You need NeXTSTEP 3.0 or NEXTSTEP 3.1 or NEXTSTEP 3.2 in order to use JetPilot.
