I have encountered a very strange problem. I am printing booklets (abt. 80 pages) where one page is in A5 format, the arranged booklet-pages by InDesign are all in A4 and I have to arrange these booklets on A3 to print two booklets at one time. I'll attack a screenshot of the final arrangement.
When printing on our office printer, every second page has a different margin, it seems like the printer changes something when turning the page, as it is always one side of the paper, the only two consecutive pages with identical margins are the ones in the middle.
I can't find out what the problem is, all the margins are correct in the arranged InDesign document so it has to be the printer.
I asked in a copy shop, they also claim it was the printer. Other colleagues though have worked with that printer before, and their booklets are completely fine. I know that the printer has its usual printer-problems including paper jamming when printing A3.
Extra question for the comments: If I cannot fix the problem in time, would it look better to abolish the baseline grid at all. Is it better that everything isn't quite right than one detail not being quite right.
