Your printing situation appears to be a sane one, so now for a test. Do

     lp -d HLL2320D_coyote ANY_FILE_YOU_WANT

Is not working, shell appears frozen but eventually returns:
gene@bpi51:~$ lp -d HLL2320D_coyote printer.cfg
lp: The printer or class does not exist.

But HLL2320D_coyote does exist. It is seen in the outputs of 'lpstat -l -e'
and 'sudo lpinfo -v'. Give

    lpoptopns -p HLL2320D_coyote
gene@bpi51:~$ lpoptions -p HLL2320D_coyote
printer-info='HLL2320D @ coyote' printer-make-and-model='Brother HL-L2320D
series' printer-type=25202710

The print queue specified by -p is queried for some information about itself.
Its reponse is given and it seems a very reasonable one.

    lpoptions -p HLL2320D_coyote -l
gene@bpi51:~$ lpoptions -p HLL2320D_coyote -l
lpoptions: Unable to get PPD file for HLL2320D_coyote: The printer or class
does not exist.

The -l option asks the queue for the specific options it offers. The response
indicates something wrong with CUPS on bpi51. I haven't any problem when doing
this and getting sensible outputs on my Debian unstable machine.

Assuming your buster machines (which are working) have similar setups to bpi51,
you couls try the two commands (and all the others in this thread) on one of

one of those machines reports this for the -l option:
