Try to reset the preferences of indesign cc
Steps for MAC / Windows : (So here you need to delete the Version 8.0 folder)
take the help of this link:
Try to export the indesign (.idml) file to .Pdf and then try to print and see.
I very much doubt RAM has anything to play in it - when I was doing a 3,200 page book I only had 2gb RAM and everything worked fine.
I suggest looking up the latest driver for your Printer and updating that. Even see if they have a "postscript driver" that you can install.
Also when Printing make sure you go to Graphics and on the Images>Send Data> set that to "Optimised Subsampling" and on the fonts make sure you select "Subset" and tick "download ppd fonts".
If your printer is an older version you may need to switch from Postscript 3 to Postscript 2 - you should try changing these and the above settings to see if there's any difference.
Is it safe to export the file as a PDF when each page has PDFs on it? So I would be creating PDFs of PDFs.
I am sending the graphics as Optimized Subsampling, but it is set to download all the fonts.
I am using the latest Postscript driver and the printer is only a few months old. It is a Xerox WorkCentre.
Maybe there is an issue with the driver itself.
