Hi,
As I said, I only modify code snippets to get to do what I needed. Improvements that you can get will be welcome.
I only tested on a Brother multifunction printer, so If anyone can test on othre devices and check if it works it will be great.

Hi
First thanks to kata for you help. Now the problem is that I can not see the image out.jpg. debido a esto:
QPixmap::fromWinHBITMAP(), failed to get bitmap info ()
I have windows 7, qt creator 2.01 based qt 4.7.0.
this is what I do
1)instal qt creator sdk
2) open qt creator, open project, I look for. pro and open it.
3) running
What am I doing wrong? or I'm missing.
-----------------------------------------------------
In the .pro :
TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .
LIBS += -lgdi32
# Input
HEADERS += qtwain.h stdafx.h twain.h twaincpp.h
SOURCES += main.cpp qtwain.cpp twaincpp.cpp
-------------------------------------------------------
Qt displays the following messages:
