On our moodle site, when selecting to print a page via the browser. it gets a really strange print format. On any other site, it gets the normal print format. Is this a theme issue?
A screenshot may be helpful... and: have you tried printing the context in a core theme like Boost or Classic? Changing the interface for testing purposes can be done really easily if your admin enabled this, by adding &theme=boost or ?theme=boost in the address bar of your browser.
If it does work with Boost, but doesn't in Adaptable, it's probably a theme issue.
