Thanks. The latest version I see on ftp.lprng.com is 3.5.8alpha2, dated
April 3.
One thing I noticed is that ps_eoj@ and ps_eoj_at_end@ didn't have any
effect until I added the following to vars.c:
{ "Ps_eoj", "ps_eoj", (char **)&Ps_eoj, FLGV,0 },
{ "Ps_eoj_at_end", "ps_eoj_at_end", (char **)&Ps_eoj_at_end, FLGV,0 },
Even completely quashing the ^D's doesn't quite solve the problem, as the
printer will wait for data as long as the connection's open. From what I
gather, ^T and ^D are technically invalid over non-serial-line PostScript
channels. Looking at netatalk's pap.c source, it appears that status
requests (^T) and EOJ (^D) are sent out-of-band, so it would be
impossible(*) for ifhp to send these over a pipe to lp=|/path/to/pap.
As pap gathers status information anyway, one can pretty easily modify
pap.c to put this on stdout or stderr. My question now is, how does one
format/route this information so it's visible in lpq? (It would be
helpful, e.g., to see "paper out" status messages in lpq.) I tried
forcing both ifhp's and lprng's poll_for_status on, but that didn't work.
I did -- once -- see a PostScript status message in the Status: (not
Filter_status:) line of lpq, but I've been unable to repeat it.
Thanks,
_Rob
(*) I guess the Adobe TBCP standard would help, but I'm a little hesitant
to try that.
