[sane-devel] Incorporating Brother Linux scanner drivers in next SANE?
On Tuesday 19 June 2007 17:15, Johannes Meixner wrote: By the way: I assume, if Brother really has a free SANE scanner driver, they would know how to contact the SANE maintainers or the Linux distributors so that their free driver is included into SANE and/or into the Linux distributions so that their users get the nice it-works-out-of-the-box experience I have a medical practice, and since we switched to paperless, we need multiple scanners. Our practice runs on Linux, including the outpatient department of the local hospital to which we are linked. Due to the large volume of scanned documents, we go through a lot of scanners. We threw our Brother scanner out because of the drivers issue - the binary drivers were tied to specific (deprecated) library versions. All new scanners we buy we make sure that they will work out of the box prior to purchase (currently all Avisions and HPs) - I simply don't get it why hardware manufacturers refuse to do business with us and so many other companies like mine just because they stubbornly fail to release driver details or release drivers under FOSS compatible licenses Brother is certainly missing out on business with us solely because of their driver policy.

[sane-devel] Avision Backend

Do you have a work around? Maybe sudo doesnt check if your UID is in group 0 in /etc/group. whereas su does check bounce you. just do sudo su then you can use your own password and become root unless this has been explicitly forbidden in the sudoers configuration Horst
[sane-devel] ADF functionality: Choosing out of 3 Products

[sane-devel] python-sane - checking for active device
What is the correct way of checking whether a device is available (plugged in, switched on) using the python SANE interface? If I switch my scanner off, sane.get_devices(), sane keeps reporting the scanner as if it was still available. If I start the program with the scanner switched off, and switch it on *after* calling sane.get_devices(), no scanner is found. Doing a sane.exit(); sane.init() prior to calling sane.get_devices() makes no difference apparently. What am I missing or doing wrong? Thankful for any advice, Horst
[sane-devel] Recent hardware w/good sane suport, 300dpi, fast ADF, USB2? (alternatives for Fujitsu fi-4020C2)

We have 3 Fujitsus which have costed $3000 each, and I see no difference in paper handling. We are throwing out the Fujitsus now, because their spares (e.g. pickups) are prohibitively expensive, and their desktop real estate is huge compared to the tiny Avision. We also have HPs, but I was not impressed with their paper handling when it gets a bit humid or paper is a bit crumpled. The SANE driver works very well; I bought the scanner, plugged it in, and after adjusting permissions (would only let me scan as root) it just works - and I mean every single feature the scanner has to offer works well under SANE. Only problem I have is I still haven't worked out how to pull the second image from a Duplex scan programmatically from Python, but works fine using e.g. XSane Disclaimer: I have no financial interest whatsoever in promoting Avision, just very happy about their product I bought Horst

That's good news. Do you use the backend at: http://www.exactcode.de/oss/avision/index.html That's the one Only problem I have is I still haven't worked out how to pull the second image from a Duplex scan programmatically from Python, but works fine using e.g. XSane Awesome, driving scanners with Python! This is exactly where I'm headed, too ;) Are you using sane.py and sane.so included in PIL-1.1.5? Yes. It's really easy, e.g.: import sane sane.init() scanner = sane.open(sane.get_devices()[0][0]) scanner.source='ADF' #select ADF sheet feeder as source scanner.resolution = 200#set resolution in dpi scanner.mode = 'Color' img = scanner.scan() img.show() As I said, only thing I haven't figured out yet is how to get the second image from a Duplex scan (other than by using xsane), everything else works to perfection Horst
[sane-devel] howto Duplex

I have no idea what its name is, but you can ask a Python-Sane device instance, which options are available: It has indeed, and I have no problems setting that property: scanner.source = 'ADF Duplex' I also notice from the scanner lights that it switches into Duplex mode too while scanning with that option set What I can't do is retrieve the second image from the scanner - only a single page image comes through instead of two Horst
[sane-devel] howto Duplex
I have an Avision AV220 duplex scanner. Works fine under SANE. However, I want to access the Duplex functionality programmatically and cannot figure out how to do it. I am using the Python SANE module to access the scanner Horst
