No, because there's no mechanism in Ethereal by which a packet dissector
can change the way printing is done or supply its own UI for printing,
and a "plugin" can currently only be a packet dissector.

Besides, the capabilities you describe don't sound like something that
should be tied to a particular protocol dissector - they should be an
option for the print dialog.
