I have 207 page document that freezes on printing, with 20 chapters in it. Memory not large enough, I guess. So I decided to save it as ch1, ch2 etc documents. I then open the ch1 copy, delete all the text in other chapters. Still end up with 180 or so blank pages with header and footer.
Is there a better way to split document into chapters without so much manual work?
Have you tried exporting it as a PDF and then printing that instead?
FYI - I regularly print documents larger than what you describe without difficulties. What you describe reminds me of errors I use to get with older printers with small internal memory size and the limitation was not the size of the document but rather the memory needed per page - often a large image would exceed the ability to render the page.
I have also had documents that would refuse to print past a certain page and that has always been a corrupted file that sends characters the printer does not know what to do. Typically, this type of error ends in the printer attempting to print hundreds of pages with a one or two line error code on it.
Another debugging technique is to send the print job as a pdf file instead of the printer, then I can inspect the pdf for damaged pages which will show up as gobbledy-gook!. I also have had documents that looked fine, but after cutting and pasting sections to a new document template eventually found a page or section that caused the problem.
I have even had documents that
I hope some of these ideas help you debug your problem. 
Thank you for help so far. Libreoffice also seems to hang when trying to export document to pdf. I wait and wait and finally get a pop-up on my computer that Libreoffice is unresponsive.
