[hylafax-users] Intermittent Postscript parsing problems

[Michael Kesler <mkesler@xxxxxxxxxxx>]

We are using HylaFAX (combined with Fax4CUPS) to transmit faxes from our application to our field technitions.  All usually works well, however we sometimes have a Postscript interpritition error:

Your facsimile job to 17137893368 was not sent because document conversion to facsimile failed.  The output from the converter program was:\n
Error: /undefined in R

Check any PostScript documents for non-standard fonts and invalid constructs

I printed the postscript document via one of our printers and it printed just fine.  The printer uses Foomatic to convert from PostScript to PCL.
I have checked several other documents (generated from the exact same piece of software that generates the failed postscript files), and it works.
