Manual: Network scanning with HPLIP and Sane (HP all in one)

[WJST]

Okay, so here it is, my manual to setup network scanning using Sane, HPLIP and DBus to be able to use (for instance) SaneTwain to scan from windows over the network or even internet.

I like comments on this, so leave a message if you like!

Basic needs:
You do need to use a HP All in one compatible with the HPLip package, see http://hplipopensource.com for more info on this.
I use the HP Photosmart C4200 All In One.

I started out with a fresh Synology DS207+ installation, only edited the smb.conf file with extra netbios support to get my mediaplayer to find it, but thats besides the point. You should have SSH conenction to your DS! I use the newest firmware for this, 844 in my case.



So; here we go.

First of all, we need to install the bootstrap to get IPKG working.
Pretty default, but if you don't know this; http://forum.synology.com/wiki/index.ph ... #Bootstrap

Next up, let's start installing:

"ipkg install sane-backends"

sane-backends has been installed. To finish the installation, you should consider installing
either xinetd or inetd to make sane-backend running.

For inetd, add the following to /opt/etc/inetd.conf:
        sane-port  stream  tcp  nowait  root.root  /opt/sbin/saned saned

For xinetd, create a /opt/etc/xinet.d/saned file like:
{
        socket_type = stream
        server = /opt/sbin/saned
        protocol = tcp
        user = root
        group = root
        wait = no
        disable = no
}

Interesting:
For inetd, add the following to /opt/etc/inetd.conf:
sane-port stream tcp nowait root.root /opt/sbin/saned saned
Lets keep that in mind, but first things first.

At the prompt about dll.conf I give in Yes, this replaces the original sane dll.conf, which is filled with a lot of sane supported drivers with a dll.conf with only hpaio in it. I;ll check it further on, so don't worry at this point.

Now, lets see if the scanner can be found:
"sane-find-scanner"

It'll probably give you an error; install libieee1284 for this: ipkg install libieee1284, if all goed well, it should give something like:

Code: Select all

WJNAS> sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

  # Your USB scanner was (probably) detected. It may or may not be supported by

  # Not checking for parallel port scanners.

  # can't be detected by this program.


Looking good.

Last thing:

Install cups. I hear you thinking; that printing isn't it? Yeah, it is, but hplip needs it. Point.

Now, lets check the sane configuration, I don't know what kind of editor you use, I use joe, simple and works like a charm, nano, vi or whatever should be gread to.

open the sane.d configuration:

"joe /opt/etc/sane.d/saned.conf"

Here is the default one

Code: Select all

# saned.conf
# Configuration for the saned daemon

## Daemon options
# Port range for the data connection. Choose a range inside [1024 - 65535].
# Avoid specifying too large a range, for performance reasons.
#
# ONLY use this if your saned server is sitting behind a firewall. If your
# firewall is a Linux machine, we strongly recommend using the
# Netfilter nf_conntrack_sane connection tracking module instead.
#
# data_portrange = 10000 - 10100


## Access list
# A list of host names, IP addresses or IP subnets (CIDR notation) that
# are permitted to use local SANE devices. IPv6 addresses must be enclosed
# in brackets, and should always be specified in their compressed form.
#
# The hostname matching is not case-sensitive.

#scan-client.somedomain.firm
#192.168.0.1
#192.168.0.1/29
#[2001:7a8:185e::42:12]
#[2001:7a8:185e::42:12]/64

# NOTE: /etc/inetd.conf (or /etc/xinetd.conf) and
# /etc/services must also be properly configured to start
# the saned daemon as documented in saned(8), services(4)
# and inetd.conf(4) (or xinetd.conf(5)).


As you can see there are a lot of IP's listed, but all commented out. ad you own range here. I give access to my entire network, way to much, but what ever, I use: 192.168.0.1/16, remove the # in front of the line!

Save the file and lets check the dll.conf


"joe /opt/etc/sane.d/dll.conf"
This should only say one thing: "hpaio"

If there's way way way more, it's probably the original sane dll.conf file, and not the one replaced by hplip; just use hpaio as first one, way on top, on its own line.

Should work out fine.

Now; first part completed; Reboot the NAS to get HPLIP find the scanner.
In the meanwhile install something like sanetwain one your client computer, you can fine this at: http://sanetwain.ozuzo.net/
Configure it to connect to your nas, and keep the port and other settings original, so only replace the IP.



Next up, run sane in debugging mode:

As you can see hpaio drive is used and you can see the scanner now in the sane twain window; mine is seen as
hpaio:/usb/Photosmart_C4200_series?serial=CN7C5R207R04VP

Lets try to get the preview scan;

I get the error:

Code: Select all

[saned] process_request: waiting for request

[saned] process_request: waiting for request

This is normally a bug in some application using the D-Bus library.
  D-Bus not built with -rdynamic so unable to print a backtrace
Aborted (core dumped)


and then sane gets killed.

I figured out this is a dbus error; fix it by giving dbus all rights possible:

edit the dbus config file:

edit /opt/etc/dbus-1/system.conf


Change:
<!-- Run as special user -->
<user>root</user>

And run: "dbus-uuidgen --ensure" to create a uuid file.

Then restart dbus:

WJNAS> cd init.d
WJNAS> dir
drwxr-xr-x 2 root root 4096 May 15 21:50 .
drwxr-xr-x 12 root root 4096 May 15 22:24 ..

Hey, weird, pid file does exist, but the process isn't there?!

"rm /opt/var/run/dbus/pid"

Try again:

WJNAS> cd /opt/etc/init.d
WJNAS> ./S20dbus start
Starting system message bus: dbus.


And try sane again:

saned -d5

Hell yeah, working like a charm, now, only thin left is get it to start in deamon mode.
Remember way one top?

Edit the following file:

/etc/inetd.conf

It probably sais:
#telnet stream tcp nowait root /usr/sbin/telnetd telnetd

The telnet deamon is disabled, no worries;
just add:

sane-port stream tcp nowait root.root /opt/sbin/saned saned

right below it.

Reboot your nas and see if everything works as it should.

Works like a charm.

And a whoopty doo.

This is awesome. Spend all evening searching the net for info on this. Got as far as installing all of the relevant packages, but your config changes were the things I was missing. Working like a charm now.

All we need next is a way to get the "Scan To" button on the HP All-In-Ones to scan directly into a folder on the Syno!

Hehe, good to mention, to be honest, I'm trying to get the scannbuttond deamon to work, but it's not going well. The project allso has been abbandoned for about 3 years now..
HP says the scan button are on the RFC list in HPLIP, but they don't know if they will implement it in the near future...

I I can get the scanbuttond to run I'll let you know, but don't get your hopes up, cuz I don't think it will work well... But hey, sanetwain works great to

Thanks for the steps WJST !

Wierdly I managed to get it working without the dbus part working properly ?!

I will now follow your steps and see if I can get the dbus part working aswell.

FYI, my AIO is the HP2840 and the NAS is the DS508.

Also I can't emphasise enough that you need to reboot as specified for some things to get kicked off correctly.

Thank you !

It works with my HP PSC 1610.

Hi,

Thanks for the very detailed instructions. I've got this almost working with a DS209+II (firmware 844) and an HP psc 2410.

I am able to scan with SaneTwain's ScanImage.exe.
However, as soon as I start to scan, Disk Station Manager's (v2.1) page with the Printer info (menu: External Devices -> USB Printer) shows a pop-up box telling me that "No USB printer is connected". Which seems kind of fair to me during the scanning process. However, after closing ScanImage.exe, the pop-ub box does not disappear and no entry in the USB Printer table becomes available like I had before starting to scan.
(the entry containing field values: usbprinter, Hewlett-Packard, PSC 2410 Photosmart, USB 1.1)

Only after unplugging the USB-printer from the NAS and plugging it back in again results in having the printing capabilities available again. In SaneTwain enabling the setting "Delay printing until program exit" (default not enabled) appears not to have any effect.

Any idea on how to make my printer automatically available again after scanning?

if anyone is struggeling to get scanning working on a hp cm1015 or cm1017 mfp, you'll have to wait untill a package with hplip 2.8.10 is available. Currently 2.8.9.1 will be installed using ipk. see https://answers.launchpad.net/hplip/+question/21217

I will try to get hplip 2.8.10 working. If i succeed, i will show how i did it (I need to learn compiling and ipk)

update:
seems inpossible... plugin doesn want to get working

This topic seems very interesting to me - will this also be possible with for instance Canon MFPs - It seems like they (a lot of them) are supported by SANE as well but there might be other requirements not fulfilled?

[Jagellovsk]

Thank you for your instructions!

I got scanning to work; but with problems:
- the saned daemon is not automatically started by inetd; has to be started manually;
- only "saned -d5" starts sane so that I can scan
- the dbus error appears every time saned is being started; so pid needs to be removed and dbus started again every time you want to scan
- after one scan saned shuts down
Additionally, the printer is no more visible (side effect of the cups installation??)
My configuration:

ds210j with firmware 2.3-1139
HP Photosmart C5280

Any suggestions?

Thank you!

Thanks for this tutorial but I have a small problem after the configuration. I have installed my old OfficeJet 6110 on my DS210J and it’s working.

But when I launch the program lance SaneTwain V1.29 to scan a document, the printer disappears from the list of connected devices (No USB printer is connected). I can scan documents but after that I can’t print a document.

I have a small workaround: I disconnected and reconnect the printer and I can print but it’s not user friendly.

Any idea or solutions

sane-backends has been installed. To finish the installation, you should consider installing
either xinetd or inetd to make sane-backend running.

For inetd, add the following to /opt/etc/inetd.conf:
        sane-port  stream  tcp  nowait  root.root  /opt/sbin/saned saned

For xinetd, create a /opt/etc/xinetd.d/saned file like:
service saned

Do you know how to solve this?

Here you have the answer:

sane-backends has been installed. To finish the installation, you should consider installing
either xinetd or inetd to make sane-backend running.

For inetd, add the following to /opt/etc/inetd.conf:
sane-port stream tcp nowait root.root /opt/sbin/saned saned

For xinetd, create a /opt/etc/xinetd.d/saned file like:
service saned
{
socket_type = stream
server = /opt/sbin/saned
protocol = tcp

Install xinetd (with 'ipkg install xinetd') and edit the file /opt/etc/xinetd.d/saned as indicated.
If it still doesn't work, try to remove both xinetd and saned, and reinstall first xinetd and then saned.

Hi all,

It has been a while, but is there a solution for the print after scanning problem?

Following this great howto I am able to scan documents, but after scanning the print function won't work anymore.
Regarding the DSM (3.0) the printer is there but the name is "Unknown".
I realy hope there is a proper solution, because reconnecting the USB is not a neat one...

Hi all,
Since 6 months, I used this solution with success. Last week I had a general power failure and it’s now impossible to scan through the network.
After many trials and errors, I have the following situation:
• When I launch the SaneTwain interface, I received the error message “Error establishing connection to host”
• If previously I start a “saned –d5”, I can scan documents with the saneTwain Interface
Where is the problem ? Do you know how to solve this?
Thanks in advance

can anyone confirm if this works with DSM 3.0-1354? I fear this was doen with DSM 2.3 release right?
