CUPS driver for EPUB?
My Linux system has a print driver that allows one to "print" to a PDF file on disk, instead of an actual printer. I have seen discussions here about if it is possible to write a printer-driver that would generate an *epub file. From what I was able to follow, the problem is that PDF is page-oriented, as a printer is, while EPUB is not. However, it is possible to convert PDF to EPUB, using software such as Calibre. So, would it not be possible to pipe the output of the CUPS-PDF driver through a PDF-to-EPUB converter to get an EPUB printer?
