Yes.

Interesting. I set up the desktop printing several years ago and don't
really use it (except yesterday to confirm that xsane would fail, but it
succeeded).
Cups on the desktop says (ignoring another device, a p2055 laser printer)
Queue name Description location Make and model
Officejet_7300 found by hp-setup found by hp-setup HP Officejet 7300 Series
hpcups 3.9.12
ss hp 7310 on ss South Salem network HP Officejet 7300 Series
hpcups 3.9.12
I guess this means I added it both via cups and via hp-setup. No
explicit mention of fax. I am loath to mess with this until I get some
success elsewhere as it is my only way to scan.
On one laptop (again ignoring P2055) I had just
ss HP OfficeJet 7300 local lan HP Officejet 7300 Series
hpcups 3.12.4
This is a cups install as I recall that that I couldn't get hp-setup to
work. I tried hp-setup again and it prints
-error: Unable to communicate with device (code=12):
hpfax:/net/Officejet_7300_series?zc=HPCC9932
error: Unable to communicate with the device. Please check the device
and try again.
I choose cancel and see the box with Printer Setup and Fax Setup,
the latter checked
If I click "add printer", hp-setup fails with the same msg as above.
However, CUPS now see both devices (plain and _fax) like yours.
xsane changes as well. Instead of "no devices" I get
"Failed to open device `hpaio:/net/Officejet_7300_series?zc1HPCC((32':
Invalid argument."
Moreover the new printer entry in cups fails to print a test page (the
old, cups-installed, entry continues to work).
Thanks for your help.
