…is strange. I assume it’s the same in other distributions, but under Debian in Iceweasel, print preview by default is lacking the option to scale content and view it in either landscape or portrait. From digging around in the configuration I found the print.whileInPrintPreview value to be set to ‘false’. Changing this to ‘true’ enabled scaling and landscape/portrait mode. I have no idea why this isn’t enabled by default, but I assume it will be at some point in a future version. The funny thing is, all of this is enabled by default in the Windows build and I’m not sure about OSX. I also found that using a custom scale produces a bug that splits the window into two panes, each with cut-off text. Whenever I close print preview and re-open it, everything looks fine.
