Print ps from script

[fy73rnd]

Hello.
I had the task of writing a script to print to a ps file with mutable parameters.
1. I never managed to add the ppd file to Illustrator so that it appeared in the PPDFileList list.
2. I came to the point of saving the preset and opening it with a script. After that, I could not resize the page. Values ​​are accepted without errors and returned upon request, but ps is written with the size specified in the preset.
I still had to change the values ​​in Placement, but before that I did not get it. I suspect that this is also impossible.
3. I indicated the path of PrintJobOptions.File, but a dialog box for saving the file opened (thanks for not error).
My question is: is it possible to do with a script what I wanted or not?

Are you sure you want real PostScript ?

Illustrator creates a lot of imagery which exceeds the native capabilities of good-old PostScript, so you might end up with incomplete files or unexpected results.

If you do want PostScript, then you must have a proper PPD file (like you tried to install) in order to let Illustrator 'dump' its communication directly into a PostScript file. Focus on solving that issue ! All other methods are not optimal or even too difficult to rely on.

You need to install the correct PPD. No page size setting can work reliably with a generic PPD. (Bear in mind page setting is never a %% comment line).
