Previous versions of Messenger Pro printed text emails as raw text (being as they were, well, raw text!). However, many modern printers don't understand raw text and expect to be fed graphically (most RISC OS apps print in graphics mode, even if you think you are printing text). Messenger Pro 5 now uses outline fonts and prints things graphically, allowing it to work on all printers. Additionally, it uses the extra functionality provided by graphical printing to embolden headings, and also dynamically scale long prints to fit on sensible numbers of pages. For example, if someone's signature spills 5 lines over onto the next sheet of paper, Messenger will now adjust the print size so that it all fits on a single sheet. Basically, I asked myself "why do I drag files into Impression to print" and Colin has tried to deal with my subsequent (sometimes crazy) requests.
