[Matplotlib-users] Quickest way to print a png file or how do you print a wxmpl figure?

[Tim B. <ti...@tb...>]

Hi all,
I am struggling with printing from wxpython. Please dont refer me to the 
wxpython wiki - been there done that.

I have two almost identical snippets of code to perform a print preview 
and a paper print of a wxmpl figure. The print preview works 
brilliantly, print to paper - nothing happens on the paper. A 0 byte 
print job flashes through the windows print spooler and that's it.

For text reports I got easy html printing going - that was indeed 
easy.... but I fought and fought with wxPrintout and gave up.... I had 
exactly the same problem - print preview worked fine - but print paper - 
empty print jobs.. I am missing something - but I dont know what. Please 
not the wiki - it's not helping me - it normally is fantastic.

Can anyone post some code that will print a wxmpl figure? Here's mine - 
it's in a state after several days of failed attempts....
               
                self.printer_config = wx.PrintData()
                print "Printer is: ", 
self.printer_config.GetPrinterName()  # no printer name is reported here -
                                                                        
                            # yet a print job is sent to the pritner
                
self.printer_config.SetPaperId(wx.PAPER_A4_ROTATED)                
                tim = wxmpl.FigurePrinter(self,self.printer_config)
                tim.printFigure(self.ProdGraph.get_figure(), "Production 
Schedule") 

Plan B - my customer wants the graph on paper - he doesnt care how I do 
it - and right now neither do I
I have wxmpl making a png image in a file - can some one give me the 
minimum lines of code - to get the png on paper - please. Lets say the 
file is called graph.png.

Thanks
