Hello Mr. Powell,
thanks for your advice.
I did as you told me:
>
> a) get the latest test version of LPRng:
>
> ftp://ftp.astart.com/pub/LPRng/private/ <<< - look here for latest test version
>
this was LPRng-3.6.23.tgz
> b) Install it.
>

> :incoming_control_filter=/usr/local/libexec/filters/fixhp
now looks like this
fleet2:
:lf=/var/log/lpd-errs
:rm=192.168.250.4
:rp=raw
:sd=/var/spool/lpd/fleet2
:mx#0:sh
:ff_separator
:lpd_bounce
:ifhp=model=hp5simx,status@
:filter=/usr/libexec/filters/ifhp
:incoming_control_filter=/usr/libexec/filters/fixhp

Lets run through what "should" happen:

> The job arrives at the spooler.
> The 'incoming_control_filter' program is run, producing the
> new control file.
> The fixhp perl script will find all the 'N ' lines, extract

> extracted 'N O' options into the Z line.

What really happens:
the cf-file gets messed up or is empty
the status file contains lines like these:
INCOMING_CONTROL_FILTER: Can't open -A0: No such file or directory at
2000-08-10-12:24:39.360 ## A=0 number=0 process=12910
INCOMING_CONTROL_FILTER: Can't open -j000: No such file or directory at
2000-08-10-12:24:39.363 ## A=0 number=0 process=12910
OKAY, so why I'm not frustrated ?
There is a Beta version LPRng-3.6.23beta2.tgz
I installed it without adding the incoming control filter and it really
works. Now all the -o options are nicely translated to -Z options even
without the :prefix stuff.
Only problem - the df* job files are not removed from the spool dir.
> Enjoy
Yes, I did.
So long, Philipp.
