Default in Print configuration Manager

How can I set a meaningful profile for 'Default' in the Print Configuration Manager? It keeps complaining:

'Unable to preview print because no Print Configuration with valid printer has been assigned to the active sheet'

(I have in Windows a default printer assigned set to A4)

While the sheet is properly associated to the system default print profile. When generating a new sheet, it creates a extremely tiny image of the model in the left lower corner outside the Viewport area. Might that be the reason? (Don't know why it does that).

After a week of trying and a few 100 wasted pages, I've given up looking for the solution for this.

Thanks, Robert
