This can be because they may slow down detection routines Note that some backends default to disabled in /var/packages/sane-backends/target/etc/sane.d/dll.conf Expand below for the full list of backends which this Synology package supports:īackend support in Synology package as of version 1.0.28-003 You can verify which backend is required for your model of scanner using the SANE Project search engine. Scanner backends which require libieee1284 are not supported by the package ( canon_pp, hpsj5s, and mustek_pp), neither is backend dell1600n_net which needed a TIFF library and in fact only supports one device. HP all-in-one models are not supported by the package since their backend hpaio is not part of a standard SANE build, and it requires significant additional dependencies. This is ideal for a headless device like a NAS, and it also frees the frontend to be quite generic rather than highly customized to each device. SANE’s differentiator is that it separates the drivers (backend) from the presentation and the scanning (frontend). SANE is an open source scanning API which has a fantastic wealth of device support. Now you can use this package to share your obsolete scanner from your Synology NAS. I recently found myself without any modern drivers for my own Canon CanoScan LiDE 20, so I decided to do something about the problem. These conditions have resulted in a mountain of perfectly good hardware being thrown away unnecessarily.

Furthermore Microsoft dropped support for the TWAIN scanning API in favour of the WIA (Windows Image Acquisition) for 64bit versions of its OS, and Apple removed TWAIN in macOS 10.9 Mavericks, superseded by ICA (Image Capture Architecture). The transition to 64bit was a similar obstacle.

Manufacturers are seldom willing to update drivers for new operating systems. Many scanners last considerably longer than they enjoy driver updates for. UPDATE – SANE version 1.0.28, new frontend AirSane package, and updated frontend software info below
