lpr printing in 7.2+

[shep]

In the interest of conserving storage space on a HP Stream 14 laptop, I decided to forego cups and utilize lpr printing. I'd saved my older setup, printcap, filter scripts and foomatic-db built ppd and it would not generate output. My printer has BRscript3 (a ghostscript variant) and I reduced the complexity and setup the /etc/example/mailcap. Trying to print from [oport]print/gv[/opor], lpr could not read /tmp.

I also tried using lpr in Devuan which also failed for the same reason. My /var/log/lpd-errs file showed:
I also check foomatic-rip outputs - yes, after upgrade cups-filters (and cups-filters-libs) from 1.22 to 1.27 i see only this:

DEBUG: Color Manager: Invalid printer name.
'CM Color Calibration' Mode in SPOOLER-LESS: Off

This seems to have been an issue brought about by version 1.27:

Does anyone have a working lpr? A quick search on marc.info/tech@openbsd.org did not show that the issue has the attention of the developers.

I have lpr working on 7.2 with the same configuration I've used for the last couple of years. Printer is Brother HL-5250DN which has native Postscript capability, but I usually use the ghostscript ljet4 driver as it's much faster. My /etc/printcap:

# Postscript output

#lp:\
	:lp=/dev/ulpt0:\
	:sd=/var/spool/output/lpd:\
	:mx#0:\
	:sh:

# Filtered output

lp:\
	:lp=/dev/ulpt0:\
	:if=/var/spool/output/lpd/filter:\
	:sd=/var/spool/output/lpd:\
	:mx#0:\
	:sh:

/var/spool/output:

/var/spool/output/lpd:

-rw-r-----  1 daemon  daemon   35 Dec  7 10:11 lock
-rw-rw----  1 root    daemon   25 Dec  7 10:11 status

Make sure the lock and .seq files exist and are writable by daemon or it won't work.

/var/spool/output/lpd/filter:

#! /bin/sh
cat | gs -q -dSAFER -dBATCH -dNOPAUSE -sDEVICE=ljet4 -sOutputFile=- -sPAPERSIZE=a4 -r600x600 -
exit 0

Some of those file permissions could probably be restricted further but it's working here.
Hope this helps.

Thanks. I'll try duplicating your PostScript setup with the exception that my printer is on my LAN. My prior setup used:HPDirect.
Update:
with this /etc/printcap

lp|HL-5450DN:\
 :lp=9100@192.168.1.3:\
 :sd=/var/spool/output/lpd:\
 :lf=/var/log/lpd-errs:\
 :sh

The print daemon starts:

Kanga# lpc restart all
lp:
        no daemon to abort
lp:
        daemon started

The steady red error and yellow paper led indicate a paper tray error but the tray was OK. I logged into the printer and the trays was set to manual feed envelope. I changed both trays to letter and it worked.
I'm interested to see if foomatic-rip filtering is still possible from the standpoint of single vs duplex and letter printing.
