I'm using the lyx-version 1.1.2, and haven't checked newer versions yet, but I doubt this bug has been fixed:
in the latex-preamble I have included "\mag=500" in order to get more text onto my sheet of a4-paper. as the papersize I therefore used twice the size of what will get printed out. for the dvi-file this works great, but the print-command does stop to work since dvips gets passed some -T option to explicitely specify the (wrong) papersize. specifying a lower papersize again does create page-breaks in the wrong places, so that only half the paper-size gets used. please inform my per email when lyx does support the \mag directive, as I am not subscribed to this list, and an upgrade doesn't make sense for me until this feature has been added. until then I'll keep printing from the command-line... strangely I seem to remember that some older version of lyx didn't have that problem, but unfortunately that binary isn't binary-compatible with the glibc I recently installed, and I don't have the sources, nor the bandwidth to waste on downloading them...
