The problem with embedded fonts in PDF mass printing applications

PDF is more and more finding its way into mass printing applications. However, PDF spool files often ask too much from a print engine resulting in aborts or, even worse, incomplete prints which may not be noticed. What is special about PDF mass printing and what can be done about it?

Is JBIG2 soon banned?

JBIG2 is a compression algorithm for bitonal images and has been developed to replace the widely used CCITT G4 algorithm because it can reach better compression ratios. However, the algorithm has received a bad reputation which has led some security experts to the recommendation not to use the algorithm anymore. Is this a wise advice or just an overreaction? Why could it go so far?

Image detection in scanned images

Detecting pictures in scanned document pages has many advantages such as better compression rates and the possibility to extract them individually.
