All I have are PDFs, without any original file. |

From what I've been reading, it's always better to use pdftops (poppler) |
| 22 |
because pdf2ps generates lower-level stuff and also converts fonts to |
| 23 |
bitmap. But both ways, I'd end up doing the conversion in ghostscript, |
| 24 |
and that's where the problem is. |
