Hell again debian-printing,

I wanted to update some of my progress with the HP ScanJet Pro 3500 f1 Flatbed
Scanner and Debian.


Trying Debian 10 'buster' (now oldstable) did not function, as there is no
"sane-airscan" package in the standard distro.  That package is available via
backports, but I did not pursue that.


As identified earlier, Debian 11 'bullseye' worked very well.  Packages I had
to install were "sane-airscan" and "hplip".  I did not require "hplip-doc" or
"hplip-gui"; the latter provides a desktop GUI with scanner status, but also
runs additional daemon processes.  For a SANE frontend I focused on the
"simple-scan" package, which has fewer options/variables than xsane.  

Simply installing the above two packages and their dependencies (with a reboot
to ensure newly installed daemons were running, such as ipp-usb), allowed
scans to function to some degree via both the flatbed and ADF.  

I was surprised things functioned without the proprietary HP binary "plug-in",
both from the command line with "hp-scan" (in the hplip package) and with
simple-scan.  However, without the binary plug-in simple-scan appeared to have
a significant memory leak, consuming 4 to 12GB of RAM when scanning ~60 pages
from the ADF.  Additionally, without the binary plug-in simple-scan could only
use the ADF scanning both sides.  Trying to scan only the front or back with
the ADF resulted in long blank pages.

While initially I had added non-priv users to th "lp" group, trying a
reinstall without that group membership still functioned OK.  Non-priv users
could access and use the scanner.


To install the binary plug-in, I ran "hp-setup -i" from the hplip Debian
package as a non-priv user while the scanner was powered-on and connected.  I
selected the USB connected scanner, downloaded the plug-in, accepted the
license, and provided root credentials when prompted.  I also proceeded to
setup a "print queue" accepting the defaults, but I'm not clear if that was
needed (or if quiting early would interrupt the setup).

Using simple-scan, selecting the "eSCL HP ScanJet Pro 3500 f1 (USB)" scanner
option was the one that worked (out of the 4 available scanner
choices/protocols listed).

After the binary plug-in was installed, there were no obvious memory leaks
with simple-scan.  Trying to scan just the "front" or "back" from the ADF
mostly worked, scanning the text side regardless of the selection.  This
functioned well enough for me to complete the task at hand, and I did not
retest with source pages that had text on both sides.


Exploring higher quality scans and color calibration, the "argyll" Debian
package maintainer (Dmitry Smirnov) was very helpful.  He generously assisted
with a version upgrade of argyll that supported my calibration target (IT8).
Unfortunately, I reached a temporary roadblock, as I do not yet have an output
calibration hardware device to measure a monitor.  It seems xsane requires
both input and output calibration configs.  For now that study is paused.


On the upside I am pleased to have a functional scanner with an efficient ADF
that scans both sides in a single pass.  This is a step up from the old HP
scanner that performed legacy acrobatics to feed ADF sheets twice for double
sided scans, and worse it required a windows computer.  Looking ahead I hope
to resume exploring calibrated scans, and also OCR.  Thanks again everyone for
the good work and support.


happy hacking,
donfede

Success scans using xsane, which I'm still learning, and simple-scan.

I still have the ADF and 2-sided scanning to explore (hopefully later this

There isn't any relationship between SANE and CUPS with either an MFD
or a dedicated scanne. There is a relationship if libsane-hpaio with an
MFD is used, but that is a long story. Part of it is on our wiki.

However, while printing and scanning are technically different, Odyx
made a good decision in bringing sane-airscan under the printing team's
umbrella.

That's fine too.

Federico, I would like two things for my records:

* Conform that

 xsane "airscan:e0:HP ScanJet Pro 3500 f1 (USB)"

  produces scanning.

* Give the output of

 avahi-browse -rt _uscan._tcp

TIA,

Brian.

In brief, success with basic scanning after installing and selecting
sane-airscan.  
Thank you Brian (and pabs that was trying to suggest this to me in IRC)!


The ipp-usb package was installed, but not sane-airscan (in this test Debian
build).  For completeness, below is the output of the requested commands after
installing sane-airscan and rebooting (just in case to remove as many
variables).


It's unclear to me the relationship between SANE and CUPS in the context with
a dedicated scanner (makes sense with a MFD).  Is configuring a CUPS
"print-queue" required?  Not sure if there's a brief explanation, or pointer
where can one learn more about this?   Clearly there is more testing to try,
and I'll read over wiki.d.o CUPSDriverlessPrinting.

Also, is there any quick info on the link between sane_open() and
sane_hpaio_open()?  Expect it's a registered callback function, but where?
The SANE API docs seem more "front end" focused (e.g.
https://sane-project.gitlab.io/standard/api.html#sane-open).


I'll continue testing functionality further, and hope to share more findings
in the next week or so.  This scanner is replacing a legacy HP Scanjet N6310,
which required a windows system.  I'm so glad to shed that dependency with
this new unit.  Many thanks again!

This appears twice and is a strong indication that the scanner is an
IPP-over-USB (7/1/4) device and should be detected as such by ipp-usb.
See

  https://wiki.debian.org/CUPSDriverlessPrinting

ipp-usb is a recommended package and should be there on the system.
Check that the service is active when the scanner is plugged into USB:

  systemctl status ipp-usb

With sane-airscan installed please give

  scanimage -L

and

  airscan-discover

Regards,

Brian.

Thanks fore the feedback Brian,

Yes, the "HP ScanJet Pro 3500 f1 Flatbed Scanner" scanner is USB only.  Below
is the output of lsusb and some other commands.  These were run from an
'older' T61 laptop (circa 2008), but expect that's not the issue given similar

I believe this is a USB-only device. Please give 'lsusb -v'.
