PostScript printing skips pages
I have a 520 pages book typeset in InDesign as multiple files book. Upon typographer's request, I exported it to a grayscale PDF (rather thank CMYK). I failed doing this job through the normal PDF export, but this is a matter of another post. Then I tried another way: I printed the book as a PS file, with CMYK-to-grayscale color conversion. What amazed me is that after the PS esport the resulting file presented random gaps in the pages. Instead of 520 pages there were only 135. When I retried the same procedure the resulting pages were 135 again. (I must specify that the PS->PDF conversion was made by MacOS, not by Adobe, so maybe MacOS is the one to blame about this issue).
