Hi imsti,
Maybe this wil help you:
LPR/LPD settings must be adjusted on the WC 58xx WebUI to allow this feature to work properly.
Through the WebUI > Properties > Connectivity > Setup > LPR/LPD > Edit... > Advanced Settings > Select 'Enabled' for "PDL banner page attributes override LPR control file attributes for job name and owner".
Kind regards,
Jeroen Wit
