That's
t = Template(templateDef, searchList=[orderData])
to you, buddy. :)
It's prob'ly possible with some work to store the precompiled
template module in the database and then exec it into a private
dictionary when you need it, but it's prob'ly easier to just
store the template definition in the databse and let it be
recompiled each time.
If you're using inheritance, you need to store the base template
modules in the filesystem. Trying to extract those from the
database would be a lot of work since you'd have to override parts
of Python's import mechanism.

At most sites, "printable page" just means omit drawing the table cells
and decorations arount the content, and perhaps substitute a few minimal
decorations instead. This can be handled by a couple #if stanzas in the
base template (if using inheritance), along with a 'print' variable in
the searchList. Then you'd only need one template for each page rather
than a pair of templates.
