[HowTo] Sane Scanner-Server with XSane Frontend

[carterb]

Hi,

there is no entry in your:

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

That might be the reason for xsane-error. Look at 2.3 on the HowTo.

Please post the output of:

sane-find-scanner

and

scanimage -L

Thanks for answer!

Hi,

there is no entry in your:

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

That might be the reason for xsane-error. Look at 2.3 on the HowTo.

# 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.

# 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)

Hi.
first of all: great work Oliver

I'm trying to get this to work in dd-wrt version v24-sp2 (08/07/10) mega (I know, this is not the right firmware).
My scanner is a HP psc 1610 (printer and scanner all in one), witch on sane-project side is reported to work "good", and also is functioning perfectly if connected directly to my ubuntu box.

kernalversion 2.4
scanimange version 1.0.21
hplip version 2.8.12-1
dbus - 1.2.16-2
dbus-glib - 0.82-1


I had some trouble to get hp-probe to find my scanner. For some strange reason the models.py searched for the models.dat fil in /tmp/root/data/models and not /opt/share/hplips/models. To make a workaround i hardcoded the right path in models.py.
Then scanimage -L gave the output:
device `hpaio:/usb/PSC_1600_series?serial=MY62SC13KY04GH' is a Hewlett-Packard PSC_1600_series all-in-one
and sane-find-scanner:
<---snipped --->
found USB scanner (vendor=0x03f0 [HP], product=0x4811 [PSC 1600 series]) at libusb:001:009
<---snipped --->

This all seams promising. But when trying scanimage >/op/tmp/img.pnm i get this error:
<--- snipped --->
arguments to dbus_connection_send() were incorrect, assertion "connection != NULL" failed in file dbus-connection.c line 3141.
<--- snipped --->
D-Bus not compiled with backtrace support so unable to print a backtrace.


How do I get some more debugging info out of scanimage?

I found out if I type scanimage -T,I get i/o error.
scanimage: scanning image of size 638x877 pixels at 24 bits/pixel
scanimage: acquiring RGB frame, 8 bits/sample
scanimage: reading one scanline, 1914 bytes... FAIL Error: Error during device I/O

i have canon MP220

can you help me please?
thanks

sorry for my english ...

Hi all,

@poulsen: What kernel version exactly?

@Parkinstein: Don't know the reason yet...? Seems to me a sane-problem (not router related). Please ask at the sane-mailing-list.
http://lists.alioth.debian.org/mailm...nfo/sane-devel

@msio: What system are you using?

[poulsen]

Hi all,
@poulsen: What kernel version exactly?

The exact kernal version is 2.4.37 from dd-wrt.

Hi

I got a little progress.
I got dbus playing a little nicer... by changing in the config-files for dbus (and /opt/etc/init.d/S20dbus) and changing the user dbus runs too the username that is on the router.
Now when i run scanimage -T I'm asked for a password.

I'll investigate a this some more and return later

Edit:
when running command scanimage -T I get this
WARNING: backend requested plain-text password
Authentification required for resource net:localhost:▒. Enter username: XXXX
Enter password:

First off; thanks carterb for maintaining the sane-backend package and for making the updated hplip package. Following this tutorial I have gotten my HP F4480 90% of the way to printing; the last 10% turns out is due to the fact that I need a minimum of 3.9.6 HPLIP to support this device according to the HP Website. Do you plan to update your 3.9.2 pacakge?

Thanks for all your great work.

I followed this howto about a year ago and was a happy user of my shared Epson RX 520, ...

Recently I installed a new desktop PC dualboot Ubuntu Maverick and Windows 7, both 64-bit - on both OSes scanning and/or printing over the network dit not work as it should:

• on W7, prints half a page, then garbish;
• scanning on W7 and ubuntu starts, but Xsane hangs before the page is completely scanned, ...

Scanning and printing with RX 520 directly attached to USB works OK on the same PC.

Also any problem for scanning and printing over the network with my older PC's (32 bit OS).

Anyone experienced the same problems ?

Thx

Hi,

@adolchristin: I can build a new version. May take some days...

@msio: Is that the newest kernel release??

[gandc]

Hello!
I've got an RT-N16 with the new Oleg (rev around 2080), and a HP LaserJet 3300 multifunctional printer.
I set up sane-backends and hplip with the help of the guide I've read here, but sane-find-scanner couldn't find my laserjet.
I searched for answers and found out that I need dbus and snmp too.
I installed both packages, but dbus gave segfault, so I replaced it with an older one.
This way sane-find-scanner still couldn't find the scanner, but hp-probe could, so finally scanning works.

The problem is that when I scan using XSane, the /dev/lp0 disappears, so I can't print anymore. I've read that this is normal and printing can be done by using cups, so I installed that package too.

It also gave segfault so once again I installed an older version of cups.
But! When I try to start cups, it crashes. The message in the system log is "/opt/var/spool/cups is not a directory!" despite the fact that the directory exists and is a directory.

That's all I think and sorry for the long post.
Someone please help me to make both printing and scanning possible!

Thanks in advance:
GandC

@carterb
I guess you have successfully built the sane-backends from the sources in your router, right? If so, could you provide some instructions how you build the sane-backends package from the sources? I tried to build the version 1.0.20 in my WL-500gPV2, however, I encountered some errors. The first problem is what to select as the build type when running ./configure? The configuration script does not automatically guess my system, so I have to set it manually. I used "mips", however, this makes the compilation fail so it probably isn't the correct build type.

And why am I building this from the sources? I just can't get my scanner to work with my router with the version 1.0.21 of sane-backends so I have to revert back to 1.0.20 which I know was working earlier. Even better would be if someone could provide me the 1.0.20 version as an ipk package which would be easier to install than building from the sources.

@carterb can you upload hplip to other server?
i'm having problems downloading from rapidshare

Please take your time; thank you for maintaining this package, I know we all appreciate it.
