Turns out that this is not a show-stopper issue for me. Paint Shop Pro includes a menu item "End TWAIN Session" that can close the SANEWinDS dialog. So: this is a non-issue. Sorry for the false alarm.

gharris999 modified a comment on discussion General Discussion

Anyway, I'm seeing this behavior with both the x64 and x86 version of SANEWinDS. It's as though it's waiting for some kind of confirmation from PSP or from the saned server, but never gets it. Here are entries from the saned.log for two successful scans: one from SANEWinDS where the twain window hangs, and one from XSANE that does not hang. I'm not seeing much of any difference between the two.

It's ancient. Paint Shop Pro, version 7.04. 32bit windows app from 2001. Seems to work just fine with the native HP twain scanning driver for my scanner. But there's no network scanning with that, so I'm excited for SANEWinDS. It's communicating over port 6566 to avision:libusb on a Ubuntu box that the scanner is connected to.

What's the name of the application?

After a successful network scan, the twain scanning dialog box has grayed-out "Close" and "Scan" buttons. The only way to continue is to kill the host graphics program calling twain via the task manager.

Correction: It's because SANEWinDS displays inactive options while scanimage does not. I can't think of any good reason to display inactive options, so I'll fix that.

Alec Skelly posted a comment on discussion General Discussion

It's because of this code in canon_dr.c (https://gitlab.com/sane-project/backends/-/blob/master/backend/canon_dr.c?ref_type=heads): /* "Imprinter" group --------------------------------------------------- */ if(option==OPT_IMPRINT_GROUP){ opt->name = "imprinter-options"; opt->title = SANE_I18N ("Imprinter Options"); opt->desc = SANE_I18N ("Controls for imprinter units"); opt->type = SANE_TYPE_GROUP; opt->constraint_type = SANE_CONSTRAINT_NONE; /*flaming hack to get scanimage to hide group*/ if (...

I'm testing with a DR-C225II, which is less well supported than your DR-C125 according to http://www.sane-project.org/sane-mfgs.html#Z-CANON. I found that I couldn't scan at all using sane-backends 1.2.1, I could scan only in color using 1.1.1, and both grey and color worked using 1.0.29.

Pascal Arnold posted a comment on discussion General Discussion

Thanks for the customization. I have compiled the code. The error message is now gone. Unfortunately, scanning still does not work. I get an IO error from the saned backend. I am now testing the older version of saned.

Alec Skelly posted a comment on discussion General Discussion

The breaking change in the canon_dr backend was introduced in 1.2.1, so if you can downgrade to 1.1.1 that should work for you. I fixed the bugs in SANEWinDS that were revealed by the bugs in canon_dr, but I'd like to spend more time testing before releasing a new version. If you can compile from the current source it should work for you now.

Hi Alex! It appears to me that SANEWinDS is currently only able to interact with Twain 32bit API, since data sources for modern Twain API are missing (confirmed with 64-bit vs 32-bit example Twain apps). Am I misconfiguring something or is it intended? In IrfanView for instance I have to enable the old 32-bit Twain API.
