In summary (and this may only apply to my scanner, which is a multi-function (printer+scanner+copier+fax) Panasonic KX-MB1520, and for which the necessary drivers are here):
In spite of needing to do so in Debian 9.2 (Stretch), from which I just upgraded to 12.5 (Bookworm), and the instructions on the Panasonic website continuing to make claims to this effect, no rules are needed in
/usr/lib/udev/rules.d and
/etc/udev/rules.d
Instead all that is needed after installing the relevant driver is to add your uderid to the lp group, since that is the group udev assigns to the multifunction device. Since it looks like I got already assigned to the scanner group automatically, if the device were just a scanner (i.e. not also a printer) udev may assign it to the scanner group automatically when connected to a usbport, and the step of adding the userid to the lp group not necessary (or even do anything anyway).
My posts here are really just a followup to the topic I started here when trying to get this same device to scan in Debian Squeeze through Stretch, and which I will now update with a reference to these posts for Bookworm.
