2. Web admin remote access
Primary configuration of CUPS is done in
/etc/cups/cupsd.conf and a web interface is provided for administration. Modify default settings that permit only localhost access to the admin panel to allow access to all machines on local network
[...] # Only listen for connections from the local machine. #Listen localhost:631 # Listen for connections from local and remote machines. Port 631 # Show shared printers on the local network. Browsing On BrowseLocalProtocols dnssd [...] # Web interface setting...

4. Access printer from a Linux client
Client machines can dispense with running a local CUPS server and its helper tools. To connect directly with the network printer, download …
sudo apt install cups-client
mkdir ~/.cups touch ~/.cups/client.conf
… and add the address of the server hosting the scanner to the file …
Alternative: If the Linux client machine regularly connects to printers on different networks it might prove convenient to download a more complete suite of CUPS packages -
apt install cups - and add the network printer via the web interface address
localhost:631 or via the native printer config utility included with some desktop environments.

5. Add the scanner
Detect attached device on the server using
sane-find-scanner [...] found USB scanner (vendor=0x03f0 [HP], product=0xe111 [DeskJet 2130 series]) at libusb:002:004 scanimage -L device `hpaio:/usb/DeskJet_2130_series?serial=CN674...' is a Hewlett-Packard DeskJet_2130_series all-in-one
Run a test …
scanimage > test.ppm
… and retrieve the (grayscale) image from the server and verify the scanner is working on the local server connection (before enabling remote access to client machines).
/etc/sane.d/saned.conf to share the scanner over the local network …
## Access list 192.168.1.0/24
Setup SANE in systemd and check status …
sudo systemctl enable saned.socket sudo systemctl start saned.socket systemctl status saned.socket
6. Access scanner from a Linux client
Install scanner tools on the client machine …
sudo apt install sane-utils
/etc/sane.d/net.conf to point the client towards the address of the server hosting the scanner …
connect_timeout = 60 192.168.1.88
Verify the remote scanner is visible to the client …
scanimage -L device `net:192.168.1.88:hpaio:/usb/DeskJet_2130_series?serial=CN674...' is a Hewlett-Packard DeskJet_2130_series all-in-one
Note: If the client fails to find the remote scanner, reboot the server and try again.
Run a test …
scanimage > test2.ppm
For a simple, graphical scanner program give simple-scan a try.
