    By writing I meant redirecting some text through
    the shell. It comes back with no sign of
    failure. I tried also this little perl:

    #!/usr/bin/perl -w

    ($i=open(P, "+</dev/lp0")) ||die "Cannot open $!";

    print "Open returns: $i\n";

    $i=(print P "Hello!\n");
    print STDOUT "Printing returns $i\n";
    close P;

    with this result:
    Open returns: 1
    Printing returns 1

    Resetting /dev/lp0 with tunelp moves the printer!

    The Epson is the only device I have.

    Except for the kernel and its modules what else
    could potentially be involved with this failure?

    Thank you.
