Subject: LPRng: BUG report/question about control file handling
Hello all,
LPRng versions >3.7.1 seem to have problems passing extra control file
parameters to filter command line. I think such problems make it
impossible to use incoming_control_filter functionality. Although this
kind of bug should be easily noticed, i couldnt find any info on this. I
can best explain this by example, so here you are: ("kalvo" is overhead
transparency in finnish)

-----------------END of example---------------
Now, take a look at those filter command lines. In version 3.6.26 there is
the -Zduplex command line option, which is missing in 3.7.4. Both control
files have it identically as added by update_z script. But in 3.7.4 it has
no real effect because ifhp seems only care about command line options,
not those in CONTROL variable. (ie. with LPRng-3.7.4 the queue testi-2s
doesnt print on both sides and with LPRng-3.6.26 it does as it should.)
Any comments? Has anyone else noticed this?
Please excuse any grammar errors :)
