[hylafax-users] HylaFAX and PCL

[Philip Gwyn <liste@xxxxxxxxxxxxx>]

Hello all,

A client needs to send faxes based on PCL.  They currently turn the PCL into PS
with an old version of GhostPCL, which is scalled down and sent with HylaFAX. 
The result (because of the scalling) leaves a lot to be desired.

After some tears, I managed to get compile TIFF support into GhostPDL 1.51
(http://www.awale.qc.ca/ghostpdl/) and learned what they mean by "cathedral".  

I've also modified ps2fax into a working pcl2fax
(http://www.awale.qc.ca/pcl2fax/).  

I notice that hfaxd has vestigal PCL support.  I hacked Fax::Hylafax::Client to
allow uploading PCL format files (see submitfax).  However, even if I upload
the file as PCL, it ends up as "data:0::docq/doc67.pcl.86" in the queue file. 
The PCL in that filename means it sees and respects the "FORM PCL" but not up
to the saving file part (should start with "pcl:").

Here is the syslog of the submit :

On to my question:

- Why was PCL support abandoned?  I seem to be seeing all the necessary hooks,
  in the source code, but its hard-coded off.  Ideally, a run-time check for
  the pcl6 binary would turn the ->supported flag on and off.
- How do I turn it on?  Beyond HAVE_PCL5, that is.

Looking in the list archives, PCL faxing seems to come up every once in a
while.  But never fully resolved.

Thank you, keep up the good work.

-Philip
