Kubuntu 8.04 rinnakkaisporttitulostin ei toimi

[launila]

Terve

Yritin pitkästä aikaa tulostaa rinnakkaisportin kautta, mutta se on
näköjään lakannut toimimasta emon vaihdon ja Hardyyn päivityksen
jälkeen. Katsoin ettei lsof näyttänyt parport0:n olevan kellään auki,
viestin lopussa pätkä syslogia. Kirjoitinporttin on ecp+epp-modessa,
kuten edelliselläkin emolla.

Googlella ei löytynyt vastauksia tähän ongelmaan. Kävin kyllä läpi ne
muutamat tulokset, mitä löysin.

Miten tämän selvitystä pitäisi jatkaa?

Alla syslogista pätkä:
