Scanner Server (Scan to PC) / Re: Scan to PC is dead
Last post by mak2109 - October 02, 2021, 09:08:49Dear bchemnet,
I can partly answer my questions after having a slightly deeper look into the py sources.
- The M_PDF functionality is implemented in the samsungScannerServer.py
As I could see, the relevant action handling regarding the dialog with multi page is taking place in class "TCPproxy" and class "_ModSaneIterator".
I fiddled a bit with the "1b a8" requests and the "a8" answers but could not bring the scanner to react in a usable manner. Therefore I added a little bit efford to complete the bash script implementation.
As you asked me to enter the script in a new tread, I opened the thread "scan2pc.sh bash script".

Scanner Server (Scan to PC) / scan2pc.sh bash script
Last post by mak2109 - October 02, 2021, 09:07:47Hi,
I have an Samsung M2070W Printer/Scanner and wished to use the "Scan to PC" functionality with Ubuntu 20.04 LTS like in the Windows environment. So I tried to use the "suld-scantopc_{version}.deb" of this repository and failed getting the python2 dependencies to work. The required dependency packages for python2 are no more available.
In order to still get this functionality, I made a tcpdump and analyzed the communication between scanner and windows driver. As a result I wrote a bash script, that does the job. The script is attached to this post.
As a prerequisit you should habe installed the (s)uld driver and sane environment to be able to do a normal (e.g. xsane) scan controlled by the Linux-PC. In addition the script requires the folowing programs (packages):
package: program
-------------- ---------------
bash: bash, wget, grep, sed
sane-utils: scanimage
imagemagick: convert
snmp: snmpget
poppler-utils: pdfunite
libtiff-tools: tiffcp
The configuration data are "stored" as shell variables or given as parameters ($1 .. $4) when you execute the script. The script has a timeout value of 600 secs (10 minutes) before it terminates (or is killed by the user typing ctrl-c (^C)).
After starting the scrip you have 10 minutes time to walk to the scanner and press the known buttons.
As I could not yet completely figure out the logic of the "1b a8" protocol that manages the dialog (next scan: yes/no) at the scanner, the scan cycle is terminated after scanning one page. To be able to do a multi-page scan you have to select "multi PDF" or "multi TIFF" except for the last page. The last page has to be scanned with "single PDF" or "single TIFF" selection at the scanner display (sorry for this inconveniance).
You can get some logging information, if you set "$ export SCANNER_DBG=true" or enable script tracing via "$ set -x". The SCANNER_DBG flag can be set too as the 4th parameter e.g.
$1 $2 $3 $4
$ . scan2pc "./" "192.168.1.99" "A4,M_PDF,MONO,200" true
If you have not set any script variable ($ export) and entered no parameter the defaults are:
$1 - active directory (./)
$2 - IP of the samsung scanner is called via "scanimage -L" (1st samsung scanner)
$3 - DIN-A4 page (A4), multi PDF scan (M_PDF), Color {COLOR|GRAY|MONO} (MONO)
$4 - debug flag {true|false} (false)
After you have selected a single scan (e.g. S_PDF), the previously scanned M_PDF pages plus the last S_PDF page are merged to one multi-page document. So after the S_PDF scan you can start a new mult-page scan using M_PDF.

Printing / Re: Howto enable SULD drivers ...
Last post by yamahito - September 30, 2021, 06:02:10Hi @ellepdesk,
Good work on the investigation!
Apologies for not responding sooner, but I was away from the office yesterday. Would you still like the output of apt update?
I am more than happy to provide any info I can, but please don't put yourself out on my account; I have a work-around, as mentioned earlier :)

If I find the time I will try to prepare a docker image, that is the only way out of this I can think of.

Printing / Re: Wifi setup - Samsung ML 21...
Last post by bchemnet - September 29, 2021, 21:15:07This feature may just be lost now. I never provided the Printer Settings utility because it was separate from the driver, and it seems that Samsung had pretty much dropped it before selling their business to HP. HP has completely dropped everything except the latest driver, which never worked with that utility. So neither HP or Samsung is providing the Printer Settings utility either. It is possible that you may be able to find a copy of the utility somewhere on the web, but you will have to dig fairly deep to find it.
Presumably the Windows driver or software still provides some way to do this. Other than that, I do not have any solution for you.

Printing / Wifi setup - Samsung ML 2165w
Last post by mauricio_matera - September 29, 2021, 08:54:28Hi all,
I am trying to configure the wifi connection of my printer. The last time I had to do that, I used the Printer Settings utility, but now it seems to not be available in the Samsung repo. Is there some similar here to setup the printer' s IP ?

Printing / Re: Howto enable SULD drivers ...
Last post by ellepdesk - September 29, 2021, 08:51:19I think I found something, it seems raspbian uses a custom version of gcc-8-base, 8.3.0-6+rpi1, where the amd64 version is just 8.3.0-6.
From what I figure apt requires the foreign package versions to EXACTLY match the native version, otherwise installation will fail.
It seems my other boards run a baseline gcc-8-base from armbian.
If I find the time I will try to prepare a docker image, that is the only way out of this I can think of.

Last post by ellepdesk - September 29, 2021, 03:37:06Hi, I found a raspberrypi running raspbian buster in my house, so I'm trying the procedure there.
Can you post the result of 'sudo apt update' to verify something?

Scanner Server (Scan to PC) / Re: Scan to PC is dead
Last post by bchemnet - September 28, 2021, 20:55:50I cannot your answer you question about M_PDF, but perhaps someone else will respond.
That said, even a limited function script may be of interest, so I encourage you to share what you have. You might want to do so in a new thread, though.

Scanner Server (Scan to PC) / Re: Scan to PC is dead
Last post by mak2109 - September 28, 2021, 13:21:31Sorry to revive this old post.
Maybe there is someone that reads it and hopefully gives an answer.
I have a M2070W and whished to use the "Scan_to_PC" function with Ubuntu 20.04 LTS.
After analyzing the tcpdump I could ask better questions and found this forum.
I downloaded the kit, noticed the python problems and can confirm the death of the python approach.
Therefore I wrote a bash script using wget, snmpget and scanimage and it works nearly as expected.
The only thing is that the M_PDF function is not yet implemented (only S_PDF).
I did not find the tcp packets, that handles the dialog about scanning the following pages.
So only one page can be scanned at a time. Multi pdf pages have to be made in an additional manual step.
Has this feature (M_PDF) been implemented in your distributed package?
How is that dialog implemented?
Any hint is appreciated.
If somebody is intrested in my sh solution, I could upload my script.
