What a coincidence today happened. In the morning I used KDEPrint's 'poster' frontend to create a "poor man's poster" in A1 size from 4 A3 printouts.
In the afternoon, a lady mailed me, asking why her KDE print dialog on Solaris didn't show the poster dialog, while her husband's openSUSE KDE did show it.
I took the time, mailed her back what I knew about the question, and included a few screenshots.
