It appears to me that the problem is connected to wrong access rights.
However, it's not the parallel port, since I can both read and write to
it, for instance with "echo Hello > /dev/lp0".
The string will then appear on the printer also connected to the port.
Running scanimage as root will cause an error in loading libraries
(undefined symbol: outb), which indicates that the program progresses
beyond the point described in my problem.
The immediate question is: What other resources than the parallel port
are accessed?
The somewhat more remote problem is how to get rid of the undefined
symbol.
