Hi all
I have a problem on printing that just happens on a large UPP project I have.

If I compile and execute the following project:

#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();
}

the printer prints the message.

But in a large GUI project I use the same code on a button handler and the printer does not move its printing head...
(In this large project I included also the Report support for printing other things on other menu/button options.)

void CSearchHistory::OnButtonOPrint(void)
{
PrinterJob pj1("History job");
Draw& w1 = pj1;
w1.StartPage();
w1.DrawText(0, 0, "Hello world!", Roman(100));
w1.EndPage();
}

Any ideads to catch the problem?

First thing that comes to mind is that you have problem with default printer.

Try pj1.Execute() before Draw& .... line to find out.

By the way, debuging facility on the IDE never worked for me...

Env: win7, Mingw and Upp 2901

I strongly recommend avoiding mingw and using free Win7 SDK... Saves a lot of troubles, debugging included, and produces better code too.
