Newest stable release 6.1.3 - and a2ps/apsfilter compiled from sources for this 
release.
>Description:
An attempt to print any text file using a2ps + apsfilter doesn't result in any 
printout; instead there is an error message in /var/spool/lpd/aps1/log:

"/usr/pkg/etc/apsfilter/basedir/bin/apsfilter: cannot open 
/var/spool/lpd/aps1/acct/lock: no such file"

After closer examination it turned out, that a2ps (or maybe apsfilter, but this 
is less likely) somehow messes the files/directories settings, and therefore 
it's unable to use proper files/directories.

My printcap:

# APS1_BEGIN:printer1
# - don't delete start label for apsfilter printer1
# - no other printer defines between BEGIN and END LABEL
aps1|lj5gray;r=600x600;q=photo;c=full;p=a4;m=auto:\
    :lp=/dev/ulpt0:\
    :if=/usr/pkg/etc/apsfilter/basedir/bin/apsfilter:\
    :sd=/var/spool/lpd/aps1:\
    :lf=/var/spool/lpd/aps1/log:\
    :af=/var/spool/lpd/aps1/acct:\
    :mx#0:\
    :sh:
# APS1_END - don't delete this

As you see from error message, a2ps insists on treating "acct" like a 
sub-directory, while in fact it is a file.
>How-To-Repeat:
1. Configure and start lpd.
2. Install a2ps and apsfilter.
3. Configure printer using its SETUP script.
4. Try to print any ASCII text file, for example with:
 "a2ps -2 -P <queue name> <text file name>".
5. Examine the log.
