printer/scanner not working on 20.04

There is a known compatibility problem with the HPLIP version form the HP pages and Ubuntu 20.04

There is an adapted package in the ubuntu repositories. Try that one.

sudo apt install hplip-gui

Manfred,
Tried that one and the terminal showed no errors.Rebooted and queue shows
jobs 'Pending' but no print after 15 minutes.

It's not "driverless". All hardware needs a driver for the kernel to talk to it. Even your mouse and USB ports have a driver.... Sounds like some marketing nonsense.

What is the output of:

lsb_release -a; uname -a; lsusb; dmesg | grep -i hp

Thanks

Actionparsnip
I questioned that myself but when I ran a printer debugging report on March
24 it gave me 630 line items of analysis(most of which I don't understand)
but under printer-make-and-model it says 'driverless,cups-filters' and then
shows '1.27.4' which is the driver version.Makes no sense.Then I attempted
to set up the printer with the exact model and it asked if I wanted a test
page.I said yes and it printed the page headed Ubuntu(the one and only
time) which showed the printer Job ID and the Driver:drvless.ppd and the
Driver Version: 1.27.4.
I can't scan that report but I've copied and pasted the few lines from the
analysis that pertain to this issue as follows.

 'cups_printer_dict': {'device-uri':
'implicitclass://ENVY_4500_series_CN5533518205X4_%40localhost/',
                       'printer-info': '',

Actionparsnip,
Further to the above,my print queues all show status as pending but end up
giving an error of 'destination not defined'.The destination defaults to
'localhost'.When I ran an HP Configuration page it shows the network status
as 'ready' but says the hostname is HP5C6D32.I tried defining it both ways
with no success.
I've seen a few fixes for this problem on the internet but I don't know the
source so I'm looking to Launchpad first.
Any luck with the output results you requested or suggestions on what I can
try next?

Further to above,would this do any good in your opinion?
One of the bug reports suggested to remove ippusbxd in the terminal ,which
automatically configures USB, by running :
sudo apt remove ippusbxd
Since my printer is not connected by USB but is wireless would deleting
this program have any effect or would I have to change the printer back to
USB for it to work?If it doesn't work can I reinstall it with :
sudo apt install ippusbxd?

sudo apt remove ippusbxd
sudo apt install ippusbxd

Yes, these are the commands to remove / (re-)install that package.

Manfred,
That didn't change a thing even though I rebooted so the further step is to
delete the printer and reinstall it using GUI printer utility.Does that
have merit and what commands should I use?

What output do you receive for the commands

sudo apt remove ippusbxd
avahi-browse -rt _ipp._tcp
avahi-browse -rt _uscan._tcp
driverless

john@john-MS-7996:~$ sudo apt remove ippusbxd
[sudo] password for john:

john@john-MS-7996:~$

Manfred,
Above is what I get for the first command but the other three lines produce
nothing either separately or as a group.
I also reviewed the network configuration pages for this printer and they
say that Network status:ready
Active connection type:wireless but then says wireless direct status:off
and then states Hardware Address (MAC).The printer screen says wireless
direct is ON and I don't know what MAC means since I have no apple
products.When I hit Print the message I get is "No destination host name
supplied by cup".Since my destination host is localhost then possibly
something is wrong with cup.

Manfred,
Since that avahi command didn't respond,I assume I don't have it installed
and since you asked you must think it's important or GUI related so should
I install it and if so what commands should I use?

What do you mean by "that avahi command didn't respond"?
I suggest that you add the option "-v" to the commands to see more details.

john@john-MS-7996:~$ sudo apt remove ippusbxd "-v"
[sudo] password for john:
apt 2.0.5 (amd64)

I added the "-v" and got the above.

1. Options like -v should not have quotes around.

2. Is the HP Envy 4500 device correctly set up for networking?
Can you ping it from your computer?

What output do you receive for the command

ippfind --ls

   Manfred,
I got no information when I pasted it into terminal so I added -v and got
the following:

expression --or expression
                        Logical OR

{service_domain} Domain name
{service_hostname} Fully-qualified domain name
{service_name} Service instance name
{service_port} Port number
{service_regtype} DNS-SD registration type
{service_scheme} URI scheme
{service_uri} URI
{txt_*} Value of TXT record key
Environment Variables:
IPPFIND_SERVICE_DOMAIN Domain name
IPPFIND_SERVICE_HOSTNAME
                        Fully-qualified domain name
IPPFIND_SERVICE_NAME Service instance name
IPPFIND_SERVICE_PORT Port number
IPPFIND_SERVICE_REGTYPE DNS-SD registration type
IPPFIND_SERVICE_SCHEME URI scheme

ippfind does not have a "-v" option.
The question now is: Why does you system not find the printer?
I am running out of ideas.

Further to above: I still have ippusbxd removed so would that affect the
results from ippfind --ls ?

So if my computer can ping the printer and the printer config says ready
and creates a print queue then the fault must be the error in 'no
destination host name supplied by CUPS' and if CUPS is incorrect can it be
corrected or worked around?Is there a way to analyse how CUPS is set up on
my computer?It all worked fine in version 18 so it must be version 20.It
makes no sense but I appreciate your efforts.

The cups configuration can be examined by browsing to http://localhost:631 (if the cups demon has been set up).
