Hi,
simple way to fix in my own experience,
remove the printer from system print-settings,
remove cups and everything cups related:

apt list *cups* | grep installed

cups-browsed/oldstable,oldstable-security,now 1.28.17-3+deb12u1 amd64 [installed,automatic]
cups-bsd/oldstable-security,now 2.4.2-3+deb12u9 amd64 [installed]

python3-cups/oldstable,now 2.0.1-5+b4 amd64 [installed,automatic]
python3-cupshelpers/oldstable,now 1.5.18-1 all [installed,automatic]

reinstall cups and
system-config-printer-common/oldstable,now 1.5.18-1 all [installed,automatic]
system-config-printer-udev/oldstable,now 1.5.18-1 amd64 [installed,automatic]
system-config-printer

check that your user was added to the lp group.

setup the printer in system print-settings (as root?) ,
choose the driver, Laserjet 1012
and select the recommended one
HP Laserjet 1012, hpcups 3.22.10
(eventually test the other two drivers provided)

If the printer is connected to a USB port cleaning the contacts
of the plug and socket also can do wonders as they can oxidize
with time.

Hope this helps.

Ciao,
Tito
