You've tried this same file on different machines and differnt printers, and it fails on all of them?
Yes, we have. Only two computers have the indesign package and license. Strangely it seems to be only a few documents which stops after page 4 on both computers, but they are documents which have been started from scratch and when working on them, don't appear to be corrupt. We have a print error code which I've tried to google (JcLB&JcLB&Jc....etc;)
And you used DIFFERENT printers, too, not the same network printer, right? If different printers are they the same model? What printers have you tried?
I'm highly suspicious that this is a print driver problem of some sort, especially since you now say it seems to be only some files. Can you PRINT those files to PDF (or to Postscript File on Mac, then Distill) and get all the pages? Does it work if you EXPORT to PDF from ID and print the PDF?
