Comment 12 for bug 510010

It was suggested that this functionality could be overridden by the user. Good
point.

Where I work, we offer PDFs of many documents and it would be really nice to
have those PDFs automatically *suggested* as the preferred printable alternative
when available. However, they should not be forced on the user. There must be
a way for the user to easily refuse this because not everyone wants a PDF (or
whatever format a given web site wants to suggest). The auto-print function
would need a mechanism to degrade gracefully.

Perhaps some kind of confirm dialogue could be used to notify the user that we
are downloading a new page for printing? Or if the download is rapid, maybe
just a visible notification on the print preview that this is a document other
than teh original HTML page. On another level, maybe users can specify in
their preferences which file formats they accept and refuse as auto-printable,
to reduce the number of confirm dialogues.

Just some thoughts...
