printing, default printer

[Riccardo Mottola]

Hello,

I want to print-preview a document. I'm on OpenBSD, cups is installed, 
but no printer is  configured.

I use Print ... -> "preview".

The only printer I see is "Unnamed". That's fine I think, I suppose I 
should be able to preview  a document without having any printer installed.

When I do preview, I get "nothing". The same happens if choose "Save".

In the console I see:

lpr: Unnamed: unknown printer

What could be wrong? I think to remember that we used to have a "Dummy 
printer". But perhaps that was on another operating system or another 
cups version? I'm unsure.
