</span>i'm able to print the 200+ dives in the following divelist (attached<br>
XML) fine in color, but i can get it to crash in b&w mode.<br>

the crash is somewhere deep in Qt, but it's due to the actual Printer::render().<br>
<br>
i also get thousand instances of these two warnings in GDB, but not in<br>
the standard console:<br>
<br>
QFont::setPointSizeF: Point size <= 0 (0.000000), must be greater than 0<br>

Gehad, you can check if you are allocating a lot of objects and if<br>
such can be freed in the appropriate location (try re-using objects,<br>
etc.), but if these are Qt memory leaks and bugs it's a much more<br>
complicated situation.<br>
<br>
also, since we are doing some "hacks" to be able to b&w print, i'm<br>
considering the proposal to remove the b&w print completely if that's<br>
the only *real* problematic mode!<br>
please, let me know if that's the case.<br><br>
