wine users - Apr 2011 - How to let a Windows App talk to a Windows Scanner Driver

Hi there,

I know that Wine usually offers the system's SANE scanners to Windows
applications using a custom implementation of the twain.dll.

In my case, I'm using a network scanner which has no linux drivers (Canon
ImageRunner 2200). I was able to successfully install the Windows driver on
Wine, and the ScanGear Tool that comes with the driver reports that the Scanner
is online and the communication is working. (Since no direct hardware access is
involved and all communication to the scanner is carried out over TCP/IP,
I'm not even sure if this is a "real driver" from the technical
point of view)

However, Windows applications cannot access the scanner, and I think this is
because of Wine's custom TWAIN implementation. Is it possible to deactivate
this and use the standard TWAIN from Windows? I do have access to an
installation of Windows XP SP3, but I have no idea which files to copy and how
to disable Wine's implementation.

Any help would be very appreciated. Best regards,
Brian Schimmel

Copy native twain.dll to Wine's system32 directory and set twain.dll to
native in winecfg.

IIRC, someone else tried this a couple of years ago with a network scanner  and
did get it to work.
