RE: Help in XML Rendering to PostScript
The code looks correct to me. I am just about out of ideas on this. If other applications are able to print to this printer successfully, then this should work. Have you tried the PS renderer yet? The JDK printing API should not come in to play on this. We are sending the print data directly to the printer. I am still a little suspicious that something between FOP and the printer is filtering the stream. As a sanity check I would try connecting the printer locally to see if it works any better.

The text renderer of course has no escape characters in it's output. If your printer was PS only then the plain text output would not have printed correctly either (unless something interpreted it for the printer). PCL however will print plain text properly (depending on line feeds and form feeds being appropriate). OK! I just did some more looking on the HP site and it looks like the 6MP should support both PCL and PostScript. If the default is PS and you want to leave the printer that way then you may need to use the PJL commands to switch the language in software (see http://www.hp.com/cposupport/printers/support_doc/bpl01378.html). If you want to try this, after you open the file output stream you would write the enter language PCL command \033%-12345X@PJL ENTER LANGUAGE = PCL\r\n to the output stream before giving the stream to Driver. After Driver has rendered the PCL you could reset the language to PS before closing the stream with \033%-12345X@PJL ENTER LANGUAGE = POSTSCRIPT\r\n.

In terms of the solution for streaming to an LPT port or network printer, is there a way to catch an error if this fails?

Re: Help in XML Rendering to PostScript
Quoting Jeremias Maerki [EMAIL PROTECTED]: I've started a Postscript renderer some time ago. It produces Level 2 Postscript and DSC comments. It's certainly not production ready, though. The whole SVG stuff is missing and it would have to be updated for the current CVS version. If it helped you I could update the code to fit with the current CVS version and post it to be integrated with FOP. You would have to give me a week or so to do that. Just tell me. Also depends on the comitters if they want the code in the current status... Whatever status the code is in, if you are reasonably happy with the design behind it, please feel free to submit it. The last thing we try (or want) to do is to foster an impression that people have to provide code-complete modules; as long as it compiles and doesn't break other code, we are happy to have it. The whole point of open-source is that we try to get code in early and often. That way other people can look at it, and take it into account, and maybe work with it, too. It also insures against the possibility that you, or anyone, just never has the time to really finish the job, and every time you look at what you have you want to improve it, and it never actually sees the light of day. I am as guilty as anyone, of holding off on submitting things into CVS until I have finished works of art. And I really get bit with the improvement bug I described above. :-) But this is just not the way to do things in open-source, as a rule. So, in summary, please feel free to submit what you have. What you can do in any case is make it clear that you wish to remain the prime on that piece of code, and that if anyone else wishes to work on it they should coordinate with you. But since you're new to Java I doubt that it will help you much because you would have to improve the code yourself (or find someone to do it for you).
