Xsane and Skanlite can't find the scanner

[elder73]

On my old dual boot system with Kubuntu 14.10 and Window 7, both of the above scanners worked fine wirelessly with my HP Des Jet printer.
When I installed Kubuntu as the sole source on the machine everything went fine. It printed OK but neither of the above scanners worked.
I went to the HPLIP site and installed the software they advise but that did not make any change. I read "Problems" on the Sane Man pages and did a couple test they suggest but the answer is always the same, they can't find any scanner. Any assistance would be appreciated.

Hooked up via network? Did you enable network scanning?

No I didn't, I thought that the printer working by wireless the other would be working also.

Can you tell me how to do network scanning. I have looked all over and can't find any information on it. Thank you.

Edit /etc/sane.d/dll.conf and remve the "#" in front of "net" and then edit /etc/sane.d/net.conf and add the IP or hostname of the scanner. Restart saned.

Thank you, no wonder Google failed me on this one. One more dumb question, how do I find the IP or the scanner?

Try "arp". It should list everything on your network with either an IP or hostname.

Example:

stuart@office:~$ arp
Address                  HWtype  HWaddress           Flags Mask            Iface
android-f8695b23c83a582  ether   XX:XX:XX:XX:XX:XX   C                     bond0
NSG-E5430-006            ether   XX:XX:XX:XX:XX:XX   C                     bond0
HPOfficjet8600           ether   XX:XX:XX:XX:XX:XX   C                     bond0
rt-ac66u-4ab0            ether   XX:XX:XX:XX:XX:XX   C                     bond0
server.smith.lan         ether   XX:XX:XX:XX:XX:XX   C                     bond0

That was from my desktop. You can see my server, laptop, phone, printer, and wifi router. No wifi devices tho...let me keep looking

This works better:

sudo nmap -sn 192.168.1.0/24

Use whatever IP set your local network is on.

Example:

stuart@office:~$ sudo nmap -sn 192.168.1.0/24

BTW, used to be that hp scanners didn't like other scanner drivers being active. My dll.conf has only net and hpaio (hp scan driver) enabled. All others are remarked out. I don't know if this is required anymore.

Thank you for all the later information. I will work my way through your suggestions. The most promising is the sane.dll file. There are some hp's there but not mine.
The network file is already commented out. Just have a bit of a problem getting to make the change at "root". Nano and Kate both work it is just where do I put the "sudo".

Try "arp". It should list everything on your network with either an IP or hostname.[/CODE]

Following is the "arp" result:

william78@william78:~$ arp
Address HWtype HWaddress Flags Mask Iface
192.168.1.1 ether 20:aa:4b:24:2e:d0 C eth0

Edit /etc/sane.d/dll.conf and remve the "#" in front of "net" and then edit /etc/sane.d/net.conf and add the IP or hostname of the scanner. Restart saned.

Did this one as well the "net" /etc/sane.d/dll.conf was already uncommented. The /etc/sane.d/net.conf file was empty. I uncommented the "localhost" and added "hp3050" for my printer scanner. This did not work either. I can only think of one word in all of this and it is a "botheration" and thank you for your patient help so far.

Try the nmap command

Try the nmap command

Sorry for the delay but nmap was not on my computer. So I got it installed wiith sudo apt-get etc. I ha ve just run this command and following is the result:

william78@william78:~$ sudo nmap -sn 192.168.1.0/24

There must be a command that lists those addresses. Elder73
