Deskjet 2752 when I try to print or scan I get a communication error

Some information, please. The outputs from:

systemctl list-units "ippusbxd*" | grep service
avahi-browse -rt _ipp._tcp
avahi-browse -rt _uscan._tcp
driverless
lpstat -l -e
lpstat-a
scanimage -L

Cheers,

Brian.

Ubuntu 20.04 installs and runs ippusbxd when the device is plugged in. This
is why port 60000 on red-truck.local is being used. In this situation the HPLIP
printing and scanning software will not work. See the IPP-over-USB sections
at

You should be able to print with this print queue. Does this command work?

  lp -d DeskJet_2700_series_CN0391W0S4_ /etc/nsswitch.conf

> avahi-browse -rt _uscan._tcp --- No output

Having no output is completely unexpected. Please would you execute

  avahi-browse -art >log.txt

and search for any sign of uscan in log.txt?

I read the info on the url you suggested and know little more than I did.

I checked my printers and I now have three printers on my printer list:

Deskjet_2700

Deskjet_2700_red_truck

Deskjet_2700_series_CN0391W0S4

What is the solution?

There was no mention of uscan that I found in the log file.  I'm
attaching the log file

The command worked, it printed out the nsswitch.conf file.

passwd: files systemd

group: files systemd

shadow: files

gshadow: files

hosts: files mdns4_minimal [NOTFOUND=return] dns

Good. From the output of the driverless command you have

  ipp://DeskJet%202700%20series%20%5BCN0391W0S4%5D._ipp._tcp.local

This a URI. *Substitute* for it in

  lpadmin -p 2752 -v URI -E -m everywhere

A print queue 2752 should show in all applications and you should be
able to print with it.

When I tried to use the command I got the following:

lpadmin: Bad printer URI "URI".

It is to be hoped that you did not type this command as given. "URI" is a
placeholder. Substitute

 ipp://DeskJet%202700%20series%20%5BCN0391W0S4%5D._ipp._tcp.local/

for it.

Hi ,

Ubuntu 20.04 is supported with few limitations in HPLIP. Hence you are seeing device busy error.

Could you please refer below link for your bug:

https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1879206

You can print via network instead of USB.
