It's a product called CombiFax developed by a German company (www.langner.com). Strange enough CombiFax is no able to handle TIFF directly. So I have to convert TIFF files to PostScript (using tiff2ps) before faxing them. In fact I tried to create TIFF output with fop 0.94, which I could convert to PostScript. But the quality of the resulting TIFF files is very poor, even if I increase the resolution. So this is not an option.

I think you're right. Their Level 2 implementation must be buggy or miss some essential features.

So I think I will open a support call with Langner now and see what they have to say about this problem.

That's interesting. And if I told you, that what FOP 0.20.5 produces is
also Level 2? There are quite a few Level 2 operations used in the
PostScript renderer there. It would be interesting to know what exactly
this fax software is and if it's really just a Level 1 implementation
maybe with some Level 2 extensions or if it contains a buggy Level 2
implementation.

But then, you say you're using a fax software. Wouldn't it be an
alternative to use TIFF instead?

Yes - kind of. I'm using fax software that takes postscript files as
input.
If I generate these files using fop 0.20.5 they work fine. If I
generate the files using fop 0.94, no way!
I really don't know, what exactly makes the difference. But with
Level 1 Postscript I would be sure, that it works.
Anyway, I have to stick to fop 0.20.5 then.

Thanks for the info!

PostScript Level 1 is not supported. It would require considerable
effort to map all the various features into Level 1. Are you still
working with 20 year old printers or why do you need Level 1?

Hi,

perhaps somebody can help me answering the following question:

Is there a way to force fop 0.94 to generate Level 1 PostScript?

I tried to set language-level in the configuration file. But this
seems to have no effect at all.
