# SANE: External Backends (Drivers)

The following table summarizes the backends/drivers that have not yet been included in the SANE distribution, and the hardware or software they support.

This is only a summary! Please consult the manpages and the author-supplied webpages for more detailed (and usually important) information concerning each backend.

There are special tables for parallel port and USB scanners from Jonathan Buzzard.

If you have new information or corrections, please send e-mail to sane-devel, the SANE mailing list.

For an explanation of the tables, see the legend.

There are tables for scanners, still cameras, video cameras, APIs, and meta backends.

## Scanners

Backends: hp4200, hpoj, niash, primax, scanwit, viceo

### Backend: hp4200

Link(s): http://hp4200-backend.sourceforge.net
Comment: Patches for newer versions of SANE are available from http://fz.eryx.net/sane/#hp4200. This backend is not yet included because nobody who owns such a scanner wants to maintain it.

Manufacturer | Model | Interface | Status | Comment
--- | --- | --- | --- | ---
Hewlett-Packard | ScanJet 4200c | USB | alpha | 8bpp, 150/300/600 dpi only, and scanned image needs postprocessing

### Backend: hpoj

Link(s): http://hpoj.sourceforge.net/
Comment: This backend isn't included because the authors of hpoj want to keep the backend together with the rest of the hpoj project. See the hpoj website for the latest releases.

Manufacturer | Model | Interface | Status | Comment
--- | --- | --- | --- | ---
Hewlett-Packard | Most HP OfficeJet, LaserJet, and PSC (Printer/Scanner/Copier) multi-function peripherals | Parport(ECP) USB JetDirect | beta | Distributed with the HP OfficeJet Linux driver (hpoj)

### Backend: niash

Link(s): http://sourceforge.net/projects/hp3300backend
Comment: This backend is not included yet because the author wants to do some code clean-up and bug fixes before adding the backend to SANE. See the hp3300 website for the latest information.

Manufacturer | Model | Interface | Status | Comment
--- | --- | --- | --- | ---
Hewlett-Packard | ScanJet 3300c | USB | alpha | NIASH00014 chip. Prototype backend available
ScanJet 3400c | USB | alpha | NIASH00019 chip. Partially works.
ScanJet 3400c | Parport (EPP) | untested | Untested
ScanJet 4300c | USB | alpha | NIASH00019 chip. Partially works.
ScanJet 4300c | Parport (EPP) | untested | Untested
Agfa | Snapscan Touch | USB | untested | NIASH00014 chip. Untested

### Backend: primax

Link(s): http://px-backend.sourceforge.net
Comment: This backend is not included because it depends on the code of the primax command line program. Therefore the author want's to keep it in the primax CVS tree.

Manufacturer | Model | Interface | Status | Comment
--- | --- | --- | --- | ---
Primax | Colorado Direct 300 | Parport | beta |
Colorado Direct 600/30bit | Parport | untested |
Network | Scanny MM100 | Parport | beta |
Storm | Totalscan | Parport | untested |
ImageWave | Parport | untested |
Genius | Colorpage-Vivid+ | Parport | untested |

### Backend: scanwit

Link(s): ftp://ftp.mccme.ru/users/ushakov/scanwit
Comment: The backend is not included because it lacks code for safe detection of the scanner and documentation.

Manufacturer | Model | Interface | Status | Comment
--- | --- | --- | --- | ---
Benq | ScanWit 2720S | SCSI | alpha | Usable, but not complete

### Backend: viceo (v0.6)

Link(s): mailto:viceo@stevencherie.net, http://viceo.orcon.net.nz/
Comment: Supports E3 and E4 family USB scanners from Genius, Primax, IBM. The backend is not included because the license situation is unclear.

Manufacturer | Model | Interface | Status | Comment
--- | --- | --- | --- | ---
Genius | Vivid Pro USB | USB | alpha |
Primax | Colorado USB 19200 | USB | alpha |
Visioneer | OneTouch 6100 | USB | alpha |
OneTouch 7600 | USB | alpha |
OneTouch 8600 | USB | alpha |
IBM | IdeaScan 2000 USB | USB | alpha |
LG Electronics | Scanworks 600U | USB | alpha |

## Still Cameras

Backends: (none)

## Video Cameras

Backends: (none)

## APIs

Backends: v4l2

### Backend: v4l2

Link(s): http://video.inodes.org/sane-v4l2/
Comment: The status of this backend is unknown. It hasn't been updated for years. The v4l2 API is now in Linux 2.5. but it's not clear if the v4l2 backend is compatible to that API.
Status: alpha
Description: Interface to Video For Linux 2 API

## Meta Backends

Backends: (none)

### Legend:

> Backend:
>   Name of the backend, In parentheses if available: Version of backend/driver; newer versions may be available from their home sites.
>   NEW! means brand-new to the current release of SANE.
> Link(s):
>   Link(s) to more extensive and detailed information, if it exists, or the email address of the author or maintainer.
> Manual Page:
>   A link to the man-page on-line, if it exists.
> Comment:
>   More information about the backend or model, e.g. the level of support and possible problems.
> Manufacturer:
>   Manufacturer, vendor or brand name of the device.
> Model:
>   Name of the the device.
> Interface:
>   How the device is connected to the computer.
> Status:
>   A vague indication of robustness and reliability.
>   - unsupported means the device is not supported at least by this backend. It may be supported by other backends, however.
>   - untested means the device may be supported but couldn't be tested. Be very careful.
>   - alpha means it must do something, but is not very well tested, probably has bugs, and may even crash your system, etc., etc.
>   - beta means it works pretty well, and looks stable and functional, but not bullet-proof.
>   - stable means someone is pulling your leg.
> Description:
>   The scope of application of the backend.
