Hi Nadya,
Yes, I just did a print to file using firefox 1.0 browser. It created a file named mozilla.ps, a postscript file. I'm running Fedora Core 2 and I used its file explorer to navigate to the mozilla.ps file. When I doubled clicked it, a window appeared and displayed the picture of the screen. I was able to zoom picture larger and smaller, so it works pretty well using firefox 1.0 under FC2.
Regards,
