It's weird that Adagio.pdf works because not only does it not work when printing to our main printer, it also does not work when printing to PDF Creator and not even when printing to Screen. Adagio.PDF is the only way I can print using customer specification. When I change it to "use selected specification", I can print to Screen, Printer, PDF Creator and Adobe PDF with no issues.

Thankfully, I don't need to use customer specification since "use selected specification" does what we need it to. The only time this would become an issue is if I needed to use different specs for different customers.
