In December my brother called me to let me know he had a possible Christmas gift for me: a Compaq Keyboard Scanner. He works for Compaq and they had a special for employees. Knowing I might not have a Linux driver for this he called to ask. I didn't know, so I started to investigate. I checked the one place I knew I could ask questions like this and get reasonably accurate answers - the Gimp Developer and User mailing lists. I posted a message asking if anyone knew about scanners and this scanner in particular. Quite a few people answered. It turns out this particular scanner is actually an OEM'd version of the Visioneer keyboard scanner. The protocol this scanner uses in not publicly available and apparently its rather difficult to get on the developers list to get the information. So much for getting support for this little device. However, the amount of information I gathered about other scanner devices, about 14 pages of printed material, turned out to be a real windfall. I decided to summarize it here in the Muse.
First, lets list the set of scanners known to have support. This list is a compilation based on what the drivers say they support and what individuals have said they are specifically using.
|User level driver for HP Scanjet II series
|Drivers for A4 Tech scanners
|User-level driver for the Nikon CoolScan SCSI
|User level program for using Mustek scanners
|User-level X program for scanning with Mustek scanners that saves files as X Bitmaps
|Driver for Mustek Paragon 6000CX
|Driver for MicroTek ScanMaker scanners originally written for ScanMaker E6, but will also work with the E3.
|Utility for Logitech scanners (including ScanMan 256)
|Early scanning package w/ EPSON support
|Genius GS-B105G 400 dpi greyscale handheld scanner
|Genius GS 4500 hand scanners and compatible models
|Logitech ScanMan+ 400 dpi handheld scanner driver
|M105 handheld scanner driver or clone with GI1904 interface
|umax-0.4.tar.gz (v0.5 may be out by now, which is reported to be very much improved over v0.4)
This one is written by Michael K. Johnson and he reports that there is sufficient documentation in the distribution for any one to add new UMAX support if they so desire.
I don't know what the difference between the pbmscan and logiscan packages is but suspect the pbmscan package is a front end to the logiscan package. The logiscan package has a front end called gifscan that uses SVGALIB (not an X interface) and saves the input into GIF files. The pbmscan package scans directly into PBM formatted files.
Commercial Scanner Products
There is only one commercially available product for scanners - XVScan from Tummy.com, which contains a graphical front end and supports a number of scanners. XVScan runs for about $50US which includes the $30 registration for XV.
SANE v0.42 - http://www.azstarnet.com/~axplinux/sane/ - is a project to create a Universal Scanner Interface. SANE, which stands for Scanner Access Now Easy, supports the following backends (device drivers):
This package makes use of the GNU Configure mechanism. Unfortunately it doesn't quite build right out of the box (there are some linking options which aren't supported by the Linux ld program). I couldn't test the programs or drivers out, unfortunately since I don't have a QuickCam or any scanners yet. Feel free to donate either, of course.
There are notes in the distribution about ongoing work for support for non-Unix platforms, but I have little interest in that so didn't really read through it.
What people are saying
And of course, what would a scanner review be without some user testimonials. These are taken from the discussions on scanners in the Gimp User and Gimp Developer mailing lists. I didn't keep track of email addresses so all I have are the first names of the respondents. As with any unverifiable testimonials, take these with a grain of salt.
I've been using XVScan with my ScanJet 4P and Linux for about 9 months, and I'm very happy with it. It worked perfectly out of the box, no tweaking or anything. XVScan costs $50, but that includes the $30 registration fee for XV and is produced by Tummy.com. Their web site is, of course, http://www.tummy.com/. - Scott
I'm using an Epson GT-5000WINS (JP model?) with a hand-made GIMP 0.54 plug-in driver. The driver is not for general use yet, but is available on-web. - Kaz Sasayama <http://www.spice.or.jp/~hypercor/hyperplay/>
I'm using an HP Scanjet IIC (predecessor to the CX) with Linux and Gimp, and am very pleased with the results. I've a feeling (unsubstantiated), that not much changed between the two models other than the driver software that HP shipped with each. There's a good HP scanner driver for Linux called 'hpscanpbm' - available from the usual sources. It's command-line driven, but offers very good control over resolution, brightness, contrast etc. Output format is pbm only, unfortunately. So far, it's the only HP driver for Linux that I've seen. - Andre
I'm using a Mustek Paragon 600II-SP, and it works quite well (just don't expect to share the SCSI bus with anything else). It's sold here (in Austria) at around $300US - Andreas
I'm using a HP Scanjet IIcx, with the Adaptec AHA152x driver and the "generic" SCSI interface. No changes to the driver were necessary. Currently using the hpscanpbm program to do all scanning. - Rob Jenkins
I'm using an HP IICX with hpscanpbm. Installation was completely painless. I added it to my scsi bus, rebooted and once I figured out which generic scsi device it was and set the permissions appropriately it worked. Probably 10-15 minutes, including compiling hpscanpbm. - Stew
I have a Microtek ScanMaker E3, which is a 24-bit flatbed scanner with a 300x600dpi optical resolution, that can be had for right around $300. It comes with some pretty decent image editing software for the Mac and for Windows, and there's a (command-line-driven) driver available for Linux (mtekscan). With any luck, the SANE (Scanner Access Now Easy) project will have a driver available in the not-too-distant future (if I ever find time to write the driver, that is. :) The SANE driver will allow standalone scanning as well as a GIMP plug-in. The driver will probably work with other Microtek scanners as well (mtekscan was actually written for a ScanMaker E6 but works with my E3). - name unknown
As for Musteks, I was considering a 30-bit, 400x800dpi Mustek scanner (I don't remember the model), until I read a review which compared that scanner to a few other scanners (mostly 24-bit). The Mustek wasn't particularly impressive; I finally decided to go with the Microtek--even though inferior "on paper" it still received a much better review. In any case, you can't go wrong with a Microtek, I think. I've also read good things about the UMAX (which are also rather inexpensive), a Canon (a little more expensive), and of course HP scanners are generally top-notch, although they also command premium prices. If you have the bucks, go for an HP, but if you want to save a few dollars and still get an excellent quality product, there are other options. - name unknown
A few people responded to my request for information on the Gimp mailing lists with information for non-Linux systems. I normally don't write about these, but I'll go ahead this one time. Note that I don't want to write about other OS's - not because they aren't any good, but because Linux works for me and I don't have the time to wander around the OS world looking for yet another OS.
Thats it. Hopefully this information will help you get started looking for a scanner and the appropriate software to use with it. I have high expectations for the SANE project to be the primary interface for low-level and user-level drivers for all scanners in the future. Once a generic interface is defined it should be easier to develop applications that can make real use of the scanners.
