Can you paginate the chunks so the appropriate PS code can be inserted or appended beforehand?
For sure. It is a very clear step by step concatenation process. It takes each individual text report in its turn in a specific order, run s them through a postscript converter, and then concatenates it to the batch file before starting on the next one. There is already a bunch of postscript commands setting up each report's layout at the beginning of each report, including a call to a funcction that is part of the overlay. As an example, one such report may begin with
pp_reset {
jnl_r_D
pp_font
0 0 moveto
}def
pp_resetIf I were to strip this report from the overall batch without changing anything, it does actually print duplex.
What are you actually sending to the printer; plaintext or PS?
Sending postscript.
Where is text to PS conversion - or is it - done?
As mentioned, text to PS is done by a script before (and as part of) the concatenation process.
See http://www.lprng.com/#ifhpdist for a short introduction. There is also a good IFHP-HOWTO by Patrick, just search google. Also check out the a2ps ASCII to postscript converter distro.
We do use that where appropriate, but I think I have shown why we had to use our own, we have a couple of keywords that will call the overlay functions properly.

Sorry, this is lvl 1 stuff -- I made a mistake.
Like Jim already pointed out Page Device is a Postscript level 2 feature.
lol. Now I feel I am stuck in a role playing session that did go so well for me. I can't even cope with level 1 stuff, and there are people in the room that are already up to level 3!
When can I use which level stuff? What does it mean to be level 4? How many levels are there....
:-)
Try to get the 'Tutorial and Cookbook' - the old Bluebook - for a quick start.
Thanks for the tip. I will look for it.
I will also look at the quick ifhp page.. I had already found the how-to and thought I will try that tomorrow. It was a little daunting, I confess.
Thanks yet again for your help.
Nemir
