that is what i did!
but in "Print Preview" dialog i have 5 buttons to choose.
2 are for zooming
"settings..." does not let me choose a printer
"page setup..." does not let me choose a printer (i.e. i'm not able to choose the big "A0" paper size now, because a smaler printer is "preset", and i'm not able to change it in this dialog. would be the right place here)
"printing..." here i am able to chose the printer, but:
it will immediately start the printing. I'm not able to leave the dialog (just changing the printer) without printing. (....that is what the button says...)
i understand, that is possible to do all the setup (of course), but the ordner is not "computer-standard" and producing usless paper.
the printing-process is a little "restricted", so i need to do a little optimisation (i.e. moving some elements in my graph, posterize the printing in 2 piece of paper... and for all this i need the preview setup whith the right printer and its paper-sizes. the printing itself is minutes away...)
