Hello,
I'm trying to use the Gnome scanner tool, but it can't find the device.
Googling shows that at least one person had no problems at all with this
printer/scanner.
Here is some command output:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
What do I do now?
P.S. please copy any replies to colin@xxxxxxxxxxxxxxxxxx, as I don't
appear to be receiving mail from this list at the moment. Not sure why.
Colin here are the Instructions I use to get a number of different USB
Scanners working. These Instruction also cover setting up a Network printer.
One thing. A number of Manufacture , example, Samsung uses Xerox
scanners on their printers (All-in one)
Most Epsons I have set up uses Epson Scanners, as far as HP goes I
really don't know.
But that is going to be the sticking point.

[edit] Setting up the Printer
I downloaded the driver set and untarred them. The drivers are available from
http://www.samsung.com/uk/support/download/supportDown.do?group=printsolutions&;
type=printsolutions&subtype=monomultifunctionproducts&model_nm=SCX-4500W&
language=&cate_type=all&dType=D&mType=DR&vType=&prd_ia_cd=06010300&disp_nm=SCX-
4500W&model_cd=&menu=download
However I did not install their script(s). Instead I pulled the following two
files out of their Unified Driver file: I added the file rastertosamsungspl
(from cdroot/Linux/i386/at_root/usr/lib/cups/filter/rastertosamsungspl) to
/usr/lib/cups/filter/
and scx4500w.ppd (from cdroot/Linux/noarch/at_opt/share/ppd/) to
/usr/share/cups/model/samsung/ Note the permissions are 644
Also did cd to /usr/share/cups/model/foomatic-db-ppds and made directory
samsung, then gzip -c /path-to-my-scx4500w/scx4500w.ppd >
samsung/scx4500w.ppd.gz
That was all that seemed to be needed. Anyway I plugged in the usb line to the
main machine here running F10, and turned on the printer whilst tailing the
messages file.
On startup it immediately recognised the printer and the messages file showed
that the device had been found correctly and culminated in:
Jul 20 20:37:32 home1 kernel: usbcore: registered new interface driver usblp
Jul 20 20:38:00 home1 hal_lpadmin: Added printer SCX-4500W-Series
A window popped up saying the printer had been added and offered me to check the
settings - all that I changed was the paper size from the US Letter to our A4
size and then I ran a test page - which looked perfect.
Then I printed a system status page from the printer itself which was fine, and
then did a test print from the main machine - all seems well.
cups started eating lots of cpu so I restarted it and it settled down nicely. I
then checked that the printer was visible to other machines on the LAN and it
worked nicely.
I have not used the ethernet cable yet, nor changed the wireless settings. I'll
have to put it on the local network and give it a sensible ip address rather
than the default 192. address that it comes with.
I have also been preparing the setup to allow scanning but not had a chance to
test that yet.
Anyway it is very pleasing that the printer is working, despite being an
unsupported printer - and only using the two files pulled from the other Samsung
linux application allowed the printer to work nicely.
[edit] Scanning
I have also now tested scanning on the scx-4500w now.
I installed sane-backends from updates-testing to give
sane-backends-1.0.20-4.fc10.i386
Then edited /etc/sane.d/xerox_mfp.conf to add two extra lines, according to
advice from other postings on the net since the Samsung printer was suggested to
work with the xerox_mfp backend setup:
# Samsung SCX-4500W
usb 0x04e8 0x342b
Then made a new file /etc/hal/fdi/information/19-libsane-scx4500w.fdi with the
following content:
<?xml version="1.0"
encoding="UTF-8"?>
<deviceinfo version="0.2">
<device>
<match key="info.subsystem" string="usb">
<match key="usb.vendor_id" int="0x04e8">
<match key="usb.product_id" int="0x342b">
<append key="info.capabilities"
type="strlist">scanner</append>
</match>
</match>
</match>
</device>
</deviceinfo>
Then I simply fired up the GIMP and asked it to scan - it found the scanner, and
it worked without any further setup.
Note that in F11 the scanner refused to work although printing worked as in F10.
After a lot of fiddling around I found that there is a workaround to what looks
like an error in the package "sane-backends-1.0.20-4.fc11.i586", and managed to
make the scanner work again -
I found that the dll.conf files in /etc/sane.d/ were interesting.
There were two files in my system - which were: -rw-r--r--. 1 root root 916
2009-10-03 12:13 dll.conf -rw-r--r--. 1 root root 664 2009-06-23 09:04
dll.conf.rpmnew
I noted that dll.conf was dated later than dll.conf.rpmnew - and the dll.conf
file did not include xerox_mfp, whereas the earlier dated dll.conf.rpmnew did
include this and in my case this is needed for the driver!
So I simply did the following: mv dll.conf dll.conf.orig cp dll.conf.rpmnew
dll.conf
To make the .rpmnew version current and fired up GIMP and asked for a scan - and
it worked just fine. I added a note to a pre-existing bugzilla report and
hopefully it will get fixed in due course.
So although I have only tested the printing and scanning capability on F10 via
the usb port it does work very nicely.
Yet to test:
* 1) printer access via ethernet
* 2) printer access via wireless
* 3) scanner access via ether/wifi
If anyone has done any other tests on this Samsung SCX-4500W and has
step-by-step setup details I would be interested to hear the information. Either
way this is a nice printer, and very quiet in operation, and does look pretty
cool too!
[edit] Network Access
The printer arrives set up with a default ip address of 192.0.0.192.
In order to get the network interface working in my local LAN which is the in
the ip range 10.0.x.x I initially booted up an old laptop and plugged in the
crossover ethernet cable that comes with the printer. Then I stopped the
NetworkManager service, and then started the "network" service.
Next step is to become root and put the laptop on the same ip range as the
printer by typing:
ifconfig eth0 192.0.0.10 up
Then start Firefox and go to the address 192.0.0.192 which immediately connects
to the embedded management interface on the printer ( called SyncThru in Samsung
parlance ) and displayed as a web page in Firefox.
Then it is straightforward to find the network page and change the ip address to
either a static ip in the range of my local LAN or let it continue to use DHCP.
In my case once I had the MAC address of the printer network interface I could
add that to my local dhcp server config and give the printer a local name.
If you are not running your own dhcp server then it is probably easier to give
it a static ip on the same range as your local LAN addresses.
The networking is arranged so that if the ethernet cable is plugged in on the
printer then it uses the wired interface and if not then it will use the
wireless interface.
So next go to the wireless interface page in SyncThru, and set up the required
wireless settings for your own local wireless access point. In my case it uses
WPA2 with AES encryption but your mileage may vary.
As soon as I disconnected the ethernet cable the printer connected to my
wireless access point and received its ip address via my dhcp server. Then
firing up Firefox on my main machine and going to the printer ip address
connected me to the embedded management interface again (SyncThru). From there
the usual range of printer settings was accessible and also monitoring of page
usage and toner use.
Next to get printing via the network instead of via USB.
a) In the main machine go to System...Administration...Printing...New Printer
b) Select "Network Printer" and the drop-down "HP JetDirect" (even though it
isn't).
c) Use the known printer IP in the "host" dialog and leave the default "Port
9100". Click "Forward".
d) Select ppd file (as in the sections above) and navigate to it - set the
remaining parameters required. Change paper to A4.
Then sent a test page - and printed a mail item - which seemed fine apart from
the page size being a touch too small for the writing at the top and bottom.
That can no doubt be tweaked as necessary later. Then any other machine on the
network can either use the printer via cups or set it as an independent route
via the network as above.
Since the wired cable had been removed this test print went via the wireless
network to the scx-4500w. If the printer is wired to your local router via
ethernet then the print goes via the wired router - you can't do wireless and
wired at the same time.
[edit] Scanning via the Network
Scanning via the network has not yet been attempted.
