Does anyone know how to configure Aqbanking so that it can connect to a printer?

I am using GnuCash 2.4.7, Aqbanking 5 on OpenSuse 12.1.

When I do the On-line banking set-up (via the Aqbanking utility), everything seems to work fine until I try to print the INI-Brief (INI Letter). I am asked for the Key password which I enter correctly and klick 'OK'. The password window closes and thereafter Aqbanking seems to do nothing but wait for the next action (no printer window, no error message, no crash, no INI Letter). There is nothing for the user to do but leave the utility.

It seems to me that Aqbanking has no connection to the printing utilities. Any ideas anyone?
