I really hate .epub format. I have tried several online and downloaded tools to convert some .epub books I have to PDF, but it still is unsatisfactory as the original page breaks are not preserved and the formatting always messes up, text is too big, fonts are lost, colors missing, graphics poorly preserve and sometimes fall on a page break, special symbols and non-English alphabets look like a botched OCR job, random chunks of text are inserted, etc. I have tried Calibre, Epubor, Zanzar, etc. The output always seems unusable.
My question: .epub files preserve the original page break locations, if I am not mistaken. Is there any .epub to .pdf converter that can simply break the pdf pages where the original print book broke the pages, and resize the text and graphics to fit (I am assuming .epub does NOT preserve the original text size data?). I want a pdf which looks as close to the original print book as possible, pulling upon any data which a .epub file might store about the original print book. I already have a .epub file, so I would rather not manually scan the entire book and compile to a PDF, if at all possible :P
Calibre seems the most flexible of the various .epub to .pdf converters I have tried. If it is possible to do this by setting certain configuration settings with Calibre (or any other software), I would appreciate anybody showing me how as I don't really know what I am doing with those settings yet. Thank you in advance!
EDIT: I have tried numerous .epub readers and Adobe Digital Editions, Sumatra pdf, and Calibre are the best I have tried by a longshot. However, only Calibre seems able to print those .epubs to a pdf, or print .epubs at all! One big problem I have is that large images that take a whole page in the print book are broken down into chunks in the ebook, regardless of the font and margin size, even when the larger image would fit on screen! one! two! same deal across e-readers
2EPUBs are basically just zipped up HTMLs. What's there to hate them so much anyway? – Karan – 2015-05-04T04:48:01.927
1I do not like that all formatting is lost, that original page breaks are not preserved, and many other formatting issues as I mentioned above are also often present in the .epub format which are handled much better by .pdf – Nathanael – 2015-05-04T15:10:30.833
That only tells me it's a badly produced EPUB. I have lots that look just fine formatting-wise. – Karan – 2015-05-04T18:09:16.690
1epub files generally only contain page breaks at the end of chapters - the whole point is you can resize the font to fit any screen and it will fill every page top to bottom. Adjusting the font size in the converted PDF with Calibre should get decent results but it will never have breaks in the exact place as a printed book. – baochan – 2015-05-04T19:54:10.260
I have tried several readers which are able to display "page break" data in the margins of my ebooks, but I have found out that these page breaks do not always correspond exactly to the print "page breaks." For example, text originally printed with multiple columns on one page are interpreted as separate pages per column. In that case, I don't suspect their is anyway to construct the original look without editing every page manually with calibri editor :P But not all books are formatted in columned text, so the page breaks should mostly be preserved, I would think. – Nathanael – 2015-05-06T15:27:31.183
@Karan perhaps the biggest issues I am still having are 1) large images are chopped up into chunks, as the examples I have provided in my edited post above, and 2) non-English symbols are preserved as horribly-low-quality images which do not scale with the text, and are highly pixelated. I am talking about probably 7-10 different .epubs produced from different sources, and read in various readers including Adobe Digital Editions, Bluefire, Calibre, Sumatra pdf, Cool Reader, etc. Unless it is a novel preserving just text with minimal formatting, most textbooks and manuals are unusable in .epub – Nathanael – 2015-05-06T16:12:12.333
Again, those examples you've shown of images being chopped up are clearly badly produced EPUBs. If the image was a single one in the file then any good EPUB reader would display it as-is, with scrollbars if required. Regarding Non-English symbols, again you're clearly using EPUBs made by incompetent people (or perhaps pirates?) Just as fonts can be embedded in PDFs to add support for various non-English Unicode characters, OTF fonts can also be added to the OPS folder and the OPF file inside an EPUB and referenced via CSS @font-face rules. – Karan – 2015-05-06T18:57:10.077

@Karan interesting. Nope, no pirated .epubs. All of the ones I am working with were accessed directly from the publisher of the print books, legally. But I can believe they were compiled less-than satisfactorily, or through some automated process without checking the results. Unfortunately this has seemed to be the norm too often in my opinion, which I suppose is why I am partial to pdfs. For now, I guess I am stuck with what I have. I have found that epubreader for Firefox does a better job of displaying .epubs than even Adobe, in my experience.
