Upon each bootup /dev/lp0 is getting created with permissions to allow root and group lp rw access.
The printer shows unavailable. print jobs error out saying "unable to write to /dev/lp0"
cupsd is running as root
parallel is running as lp
As soon as I add +rw to all users it is fine. This does not feel like the correct "solution".

cups-driverd
cupsd-helper(8) Apple Inc. cupsd-helper(8)
NAME
cupsd-helper - cupsd helper programs
SYNOPSIS
cups-deviced request-id limit user-id options
cups-driverd cat ppd-name
cups-driverd list request_id limit options
cups-exec sandbox-profile [ -g group-id ] [ -n nice-value ] [ -u user-id ] /path/to/program argv0 ... argvN
DESCRIPTION
The cupsd-helper programs perform long-running operations on behalf of the scheduler, cupsd(8). The cups-deviced helper program runs each
CUPS backend(7) with no arguments in order to discover the available printers.
The cups-driverd helper program lists all available printer drivers, a subset of "matching" printer drivers, or a copy of a specific driver
PPD file.
The cups-exec helper program runs backends, filters, and other programs. On macOS these programs are run in a secure sandbox.
FILES
The cups-driverd program looks for PPD and driver information files in the following directories:
/Library/Printers
/opt/share/ppd
/System/Library/Printers
/usr/local/share/ppd
/usr/share/cups/drv
/usr/share/cups/model
/usr/share/ppd
PPD files can be compressed using the gzip(1) program or placed in compressed tar(1) archives to further reduce their size.
Driver information files must conform to the format defined in ppdcfile(5).
