we use 3 PC and 3 HP 6970 allinone connected via powerline. To choose one HP 6970 as standard printer for a PC is easy and works well. But simple scan don't use this standard device for scanning.

Is there a possibility to set one HP device as standard for scanning?

scanimage -L
device `hpaio:/net/officejet_pro_6970?ip=192.168.8.10&queue=false' is a Hewlett-Packard officejet_pro_6970 all-in-one

device `hpaio:/net/officejet_pro_6970?ip=192.168.8.20&queue=false' is a Hewlett-Packard officejet_pro_6970 all-in-one

device `hpaio:/net/officejet_pro_6970?ip=192.168.8.30&queue=false' is a Hewlett-Packard officejet_pro_6970 all-in-one

Thanks for your help

  • I think its going to be complicated but the only way I can see this happening is by setting an Operation Policy in CUPS which restricts operations to a specific IP address chosen from your 192.168.8.10/20/30 range. From your browser go to the CUPS page here: localhost:631/help/policies.html

  • this would also restrict printing to the choosen IP?

  • That's the theory. How it might work in practice will require some experimentation.

Short Answer

To scan from your second scanner:

simple-scan hpaio:/net/officejet_pro_6970?ip=192.168.8.20

Long Answer

From Debian's SaneOverNetwork:

Scanning with a Network HP all-in-one (aio)-1

To scan over the network from a scanner on an HP aio (one which is not connected by USB to a computer) you need only to install libsane-hpaio (without its recommended packages) and pass the URI of the scanner to the frontend. A non-free plugin might be required for the scanning function.

The format of the URI is:

hpaio:/net/<aio_model_name>?ip=<IP_address_of_the_aio>

This URI can be given directly to the frontend. It can also be provided automatically to the frontend if either a print queue with the hp:/... backend is set up or mDNS broadcasts for the scanner are done by the aio. Automatic discovery will happen via the print queue if both it and mDNS are available as discovery methods.

The IP address could be known from the way the aio's networking was set up; or it could be got from the aio's front panel or deduced from the output of

/usr/bin/lpinfo -v

Each printer model supported by the installed verion of libsane-hpaio is listed in /usr/share/hplip/data/models/models.dat. Model names are enclosed in square brackets; like so, [envy_4500_series].

A frontend can be started with (for example):

simple-scan <URI>

Typing the URI each time can be avoided by exploring what your DE (Desktop Environment) or WM (Window Manager) offers for customising a command. For typing from a terminal you might find a simple alias sufficient.

There are more options for setup as the link describes. The information on alias to save typing might be very helpful.
