Right, there was a topic 'Cannot print without showing the print 
dialog'. Your last answer:
"""No, you are saving a wx.PrintData object.  I think since you are not 
letting the dialog be shown then there is not a printer being selected. 
 So you need to save the wx.PrintDialogData so it can get the printer 
selection from there.  (Assuming that you used it in a print setup 
dialog.) """

It's my first try with the print framework, so mayby I miss something 
but printing is a step after fetching the PrintDialogData. I just want 
to get Instances of wxPrintDialogData and wxPageSetupDialogData filled 
with the data of the default printer, without showing and accepting the 
dialogs.

I cannot confirm that (wxpy 2.6.2.1 pywin 2.4.2 on w2k sp4):

self.printerdata = wx.PrintData()
self.printerdata.SetPaperId(wx.PAPER_A4)
self.printerdata.SetOrientation(wx.PORTRAIT)
data = wx.PrintDialogData(self.printerdata)
dlg = wx.PrintDialog(self, data)
dlg.GetPrintDialogData().SetSetupDialog(True)
dlg.ShowModal();
data = dlg.GetPrintDialogData()
self.printerdata = wx.PrintData(data.GetPrintData()) # force a copy
dlg.Destroy()
print self.printerdata.GetOrientation()
returns 1 instead of wx.PORTRAIT

But anyway, how can I build a list of the wx.PAPER_* values. Should I 
type them manually or can I fetch them somewere ?


Another  question:
self.pagedata = wx.PageSetupDialogData()
dlg = wx.PageSetupDialog(self,self.pagedata)
dlg.ShowModal();
self.pagedata = dlg.GetPageSetupDialogData()
dlg.Destroy()

print self.pagedata.GetMinMarginTopLeft()
print self.pagedata.GetMinMarginBottomRight()
 
return always (0,0). Tried it with several printers. According to the 
docs this should be the minimum margins of the printer. Some hints ?
