changecartridge - a program for changing the ink cartridges
                  in the Lexmark 5xxx and 7xxx printers.

To change the ink cartridges in a Lexmark printer you must move the
print head out of its parking corner, so that you can reach the
cartridges. Lexmark only provides a Windows program for doing this. To
not need to boot Windows for changing the cartridges there is this
script. Simply call it with:

   changecartridge

on the command line and follow the steps described on the screen.
The printer is assumed to be at the parallel port #1 (/dev/lp0), but
this setting can be changed by editing the definition of the PORT
variable in /usr/bin/changecartridge.
