Re: LPRng: problem apparently with PJL?

Hi Dave,

So it sure looks as though these printers aren't responding to PJL, and
so ifhp thinks that it needs to wait & retry, endlessly.  I don't see
anything in the printers' configuration that would address this.  Does
anyone have any suggestions?
Thanks ...

 

I'm not into HP LJ4, but if it really can't handle PJL, ifhp.conf is 
probably
your place.
You mentioned that you tried stopping the PJL querying. What did you 
already try?

First thing:
Did you give ifhp an idea of the model to use? For us, it looks like this
in the printcap (often found in /etc/printcap):
______________
sw1|i08pr_sw1|studpr_sw1
....
:lp=i08pr-sw1.atis-stud.uni-karlsruhe.de%9100
:cm=Studipool HP 8150 DN
:ifhp=model=hp8150,status
.....
______________
For you "ifhp=model=hp4" would be right. Another try would be to disable 
status-queries
in general:
ifhp=model=hp4,status@

If it really is a PJL-problem, you can look into ifhp.conf for the 
following:
__________________
#--- START language setup
## default is to turn everything on
## We assume that we have PostScript, PJL, PCL, and text 
support                            
## Text is just PCL without any control sequences
##

pjl
pcl
ps
text
_______________
and change "pjl" to "pjl@". That disables PJL as a "valid" language.
I never tried this, but thats what the options intenionally have been 
made for, I guess :-))
There are also quite a few options for fine-tuning the query of the 
printers in ifhp.conf.

But it's anyway strange, as the HP4 is considered PJL-capable in the 
ifhp.conf.
[i would wonder why not, because it's probably an invention of HP :-) ]

Furthermore, i'm not sure if the concept of LPRng works fine without having
any idea of the printers status.
Good luck!

regards,
Rainer
