Xsane doesn't find network scanner (printer works)

Question

I have an HP Deskjet 1050 j410 all in one setup as a network printer/scanner on a raspberry pi. My laptop running ubuntu 16.04 finds the printer and scanner and it all works. All I had to do was edit /etc/sane.d/net.conf and put the ip address of the pi. On my desktop also running ubuntu 16.04 the printer is found and works, but xsane doesn't find the scanner. I also edited the /etc/sane.d/net.conf file to include the ip address of the pi and it doesn't find it. Where can I go from here? Is there another file I can edit to help xsane find the scanner?

Answer 1

I faced a similar issue (works on one computer and not another). The resolution was to make sure HPLIP was set up on the non-working one. Here's what worked for me:

apt-get install hplip python3-pip simple-scan
pip3 install pyqt5
hp-setup

Update

There's an even simpler way which can avoid the pyqt5 requirement:

apt-get install hplip simple-scan
simple-scan $(hp-makeuri SCANNER_HOSTNAME_OR_IP | grep ^SANE | cut -d ' ' -f 3)

Substitute the hostname or IP address of your scanner instead of SCANNER_HOSTNAME_OR_IP
