Gscan2pdf is an interface for scanning documents to PDF on the GNOME desktop that uses SANE to communicate with the scanner. Several user interfaces have been written to combine SANE with an easy user method of controlling it. The front end only has to obtain the set of options from the user once. Using the SANE API, the front end simply has to 'play back' the same set of options for each scan, driving the document feed in between scans to load the next sheet of paper. Many scanners support the attachment of document feeders which allow a large number of sheets of paper to be automatically scanned in succession. Various types of unsupervised batch scanning are also possible with a minimum of support needed in the back end (driver). Similarly, the 'net' back end passes requests and data between the local front end and the remote host. The saned daemon acts as a front end locally, but simply passes requests and data between the network connections and the local scanner. On client machines a 'net' back end (driver) connects to the remote host to fetch the scanner options, and perform previews and scans. On a host with a scanner, the saned daemon runs and handles network requests. One consequence of this separation is that network scanning is easily implemented with no special handling in either the front ends or back ends.

Other options can be presented using GUI elements appropriate to their type e.g., sliders, drop-down lists, etc. By convention there are several 'well known' options that front ends can supply using convenient GUI interaction e.g., the scan area options can be set by dragging a rectangular outline over a preview image. Each option has a name, and information about its type, units, and range or possible values (e.g., enumerated list). These options specify parameters such as the resolution of the scan, the scan area, colour model, etc.

Whereas a TWAIN driver handles the user interface as well as communications with the scanner hardware, a SANE driver only provides an interface with the hardware and describes a number of 'options' which drive each scan.

They are a few ways to get it working, but there is no guarantee unfortunately:ДЎ) use the USB Redirection to get it redirected into the Terminalserver, and install it there: Twain isnвЂt a Linux compatible way of access but a kind of pure Microsoft ones, so we canвЂt force an integration even if I would be happy toрџ„ДЄt the moment: USB Scanner is a tough topicвЂ¦

Does anyone have information on TWAIN support for iGel devices within XenDesktop 7.x? Looking to use some Canon DR-C225 and M190 scanners and would like to avoid the USB virtual channel.
