That's probably way more JavaScript than I'm likely to do anytime soon but it's good to know that such techniques can be made to work. >> Would that be ReportLab perchance?

Ok. I've done printing from the two methods described in wxPython. The HTML variety is good for very simple cases but quickly runs out of power even long before full HTML would. The full wxPrint is a bit like coding in Assembler and has some bugs. > Another option is to send the direct PCL yourself.

Hadn't thought of it for the bigger ones needing lots of PCL but it could be done easily enough with a little work to abstract some of the basic drawing.
