The problem arises from the code

printjob.cpp
::Execute0

if(!PrintDlg(&dlg)) 
{
    DWORD x= CommDlgExtendedError();

the CommDlgExtendedError returns 0x1008 which means
"A default printer does not exist."

How to solve this?

Again, the following small project runs well...

#include "teste2.h"



teste2::teste2()
{
	CtrlLayout(*this, "Window title");
	btBut <<= THISBACK(OnBut);
	

	
}

void teste2::OnBut(void)
{
	PrinterJob pj;
	Draw& w = pj;
	w.StartPage();
	w.DrawText(0, 0, "Hello world!", Roman(100));
	w.EndPage();
	
}

GUI_APP_MAIN
{
	teste2().Run();
}

It seems that it is something related with that project/executable...

Thanks

Well, the general approach I am using in cases like this (you have big project with strange behaviour of unknown source) is to "exclude" the code until it starts working.

E.g. rename "GUI_APP_MAIN" of above code to "DoTest", then put all of that to your project (temorarily) and call DoTest at beginning of your big app GUI_APP_MAIN. If it does not work, there is a bug in global constructor somewhere. If it works ok, start it moving down the code... until it stops - then you have identified what makes the error.
