Yes, the HP scanner I use just opens up a local webpage that I open up 
in in a browser. All scanning functions are performed on the printers 
local-only webserver. It seems to work nicely as I have every OS under 
the sun scanning from it.

Plenty of scanners can now email or scan to cifs/samba shared drive too.
Getting scan into my openbsd box not an issue since my HP MPF can do all

Re: Flatbed scanner that works well with OpenBSD?

2018-01-21 Thread Freddy Fisker
I have an Epson WP-4595 Network Multifunction Printer, and the scanner 
works fine with XSane.


I also have an older Epson Perfection 2480 Photo USB scanner, but it needs 
a Firmware to run.




Re: Flatbed scanner that works well with OpenBSD?

2018-01-21 Thread Robert
A couple of people started to recommend network-attached devices.

I would be careful with this. Those devices often utilize an ancient embedded 
Linux or Windows, with lots of proprietary daemons of questionable quality 
("features before security!") exposed to the network.
There are tons of CVEs and vulnerabilities for those devices.
If you consider such a device, at least do a vulnerability search about it 
first.
If you are paranoid, connect it through a dedicated NIC and non-routed local 
network to your computer.

For a single user I very much prefer a locally attached USB device than 
introducing such a risk into a network.
YMMV.

Robert

I have a couple-of-years-old HP all-in-one network printer/scanner, it
was pretty cheap (I think I bought it in LIDL), works fine with xsane,
I'm using the hpaio/hpcups/hplip drivers over the network from OpenBSD
(also no problems with macos/windows).

I doubt the same model (Officejet_4500_G510g-m) would still be available
but in general the hpaio-supported things shouldn't be too awkward.

This is a very silly question. Most modern all-in-one office grade
devices can scan directly onto an umass device or into the e-mail. You
don't need OpenBSD to scan. The scan quality fall within technical
requirements you have.

That being said I have three scanners currently attached to my OpenBSD
desktops at work and at home and all of them work perfectly. They are
older devices.

1. Epson Perfection 1650 (plug and play)

2 .Epson Perfection 1670 (use cabextract to get a firmware needed to
scan from Windows installation disk)

3. Epson all-in-one WorkForce 845 (plug and play but printer is 
paperweight but good enough for me to print from my smart phone with
proprietary driver)


I see people complaining about CanoScan LiDE line of Canon "scanners".
Those scanners come without power supply and they are supposed to draw
the electricity from USB cable. They cost about $10 new. Well you get
what you paid for. 

Now in whole honestly Epson started selling $100-$200 flatbed scanners
here in U.S. which do require epkowa binary blob driver so they are
Linux only. Those scanners are no better than what I have. Now real good
scanners like Perfection V850 Pro ($1000) are fully supported but you
probably don't need that unless you are digitizing massive amount of
old photos and negatives.

Hi,

My scanner also stopped working somewhere around 6.0 I think. I didn't need it 
since then and therefore didn't bother to file a bug report (I know...).
Don't know if it's the same root cause, but mine looks like a USB stack problem 
(?).
Note: This is a Dell Optiplex 3020, that has the XHCI problem mentioned by 
someone in 2015 (hangs during boot); I have to disable the xhci device in the 
kernel in to boot (full dmesg at the end).

Re: Flatbed scanner that works well with OpenBSD?

2018-01-19 Thread Ax0n
Slightly related, I have a CanoScan LiDE 100 that used to work great with
OpenBSD, using either ScanImage or simple-scan. It's detected, but sometime
around OpenBSD-5.6 it stopped working. I use it infrequently enough, and I
have enough computers that I usually just give up and have my wife use her
Windows laptop to scan for me. I have a slightly vested interest in having
my only scanner work with my main daily desktop/laptop OS.

I'll try installing some old versions of OpenBSD and see if I can find
where it broke, and post dmesg's of the before/after mess, if anyone thinks
that would help.

Well, I just bought a CanoScan 9000F MkII specifically because it was
marked as fully supported on that list, and I can say it does NOT work
on OpenBSD; scanimage -L detects it just fine but attempting to scan
gives an I/O error. As a workaround I plugged it into a Linux laptop,
started saned, and scan seamlessly from OpenBSD with scanimage's network

In the past I used a CanoScan LiDE 20 quite regularly from OpenBSD, but
that was several years ago.

Hello misc@

I'm currently looking to purchase a scanner that works well with OpenBSD.

I'm aware of the list provided at: 

http://www.sane-project.org/sane-mfgs.html

but I recently purchased (and returned) a scanner that was listed as being
fully supported on that list because no matter what I did, I couldn't
get it to work right with xsane or scanimage.  Though I purchased it used,
so it's possible it may have simply been broken from the get-go.

Does anyone happen to know of a scanner that is *known* to work well
with OpenBSD?

I don't really have any hard requirements other than it should be able
to scan in color as well as black and white, and should be able to scan
up to a minimum of 600 dpi (1200 dpi or more would be nice, but is not
required).

I have a feeling that the majority of scanners currently on the market
meet or exceed that, so hopefully anything will work well so long as it's
compatible with OpenBSD.

Many thanks for any assistance anyone can provide.
