Print it to a PostScript file and ps2pdf the output. Worked for me for the Mustang POH (but sadly now I can't find the result file, and the computer on which I installed the key has long since been reinstalled; it'll turn up somewhere, I'm sure). I think it might have been slightly more complicated; I ended up doing something like printing it to a samba printer on a linux box and grabbing the file out of the spool directory, or somesuch. As far as eflightmanuals.com goes, I'll agree that he's a little slow. But the prices aren't awful, and the service is generally pretty valuable, given that most of these things are not available online. Note that he obviously *doesn't* own the copyright on the original works*, so I'm not sure of the level of protection he's legally afforded by the encrypted PDF. * Which, at least for the US airplanes, are government documents and therefore uncopyrightable. The only legal restriction on their distribution would be their security classification, AFAIK. IANAL, blah blah blah.
