Re: [sane-devel] Add support for old OKI scanners

[Sungjoon Moon via sane-devel]

Hi, Thank you for your reply It's glad to know you have same model. 1. Do you think porting python2 to python3 would be useful? I think if driver exists we can just use sane without their software. 2. I will use ghidra to decompile library file and try to do reverse engineering. Do you think it would be okay to be merged into upstream (legal issue). 3. I found some guides in official documentation(http://www.sane-project.org/docs.html), is there any resources you recommend? 4. What backend codes would you recommend to read as an example.

I own a Sindoh C200 scanner, which is the OEM version of OKI MC561dn (source: https://m.blog.naver.com/dgwox200/10189835689, in Korean). On their website, they provide Red Hat and Debian drivers (each has x86_64 and x86 versions) Driver page: https://www.oki.com/eu/printing/support/drivers-and-utilities/colour-multifunction/44473204/ Interestingly, their Red Hat driver has debug symbols, but Debian does not. And they even have a libsane-oki.so library file, so that's a good start. I think it's GPL licensed, so it might be possible to ask for the source code. However, I'd like to start writing drivers for this scanner, so I'd like to ask for help. Well I might be able to help here. I actually *do* have an OKI MC561dn that I use for daily colour printing. The scanning backend that OKI provide is actually pretty good, but I noticed that some of the dependencies (IIRC python) conflict with modern distros and I have not been able to install it on my up-to-date Linux Mint. What kind of help do you need? Cheers, Ralph
