In just under a year, I got back around to this problem and solved it for
myself. The answer is libpoppler for python, which makes it easy to render a
PDF to a cairo surface. That plus the testprint example (which appears a bit
dated -- it has a number of calls that don't work), and I have a working
solution in just about 25 lines.
In case anyone has my same question (just now googling for a solution my
initial question was the top hit I found), here's the code:
import gtk
import poppler
import os.path
class PDFPrinter:
def __init__ (self, fn):
self.d = poppler.document_new_from_file(fn,None)
def draw_page (self,operation, context, page_num):
page = self.d.get_page(page_num)
page.render_for_printing(context.get_cairo_context())
def setup_printer (pp):
po = gtk.PrintOperation()
po.set_n_pages(pp.d.get_n_pages())
po.connect('draw_page',pp.draw_page)
po.set_export_filename('/tmp/foo.pdf')
po.run(gtk.PRINT_OPERATION_ACTION_PRINT_DIALOG)
def print_pdf (pdf_filename):
if not pdf_filename.startswith('file'):
pdf_filename = 'file://' + os.path.realpath(pdf_filename)
setup_printer(PDFPrinter(pdf_filename))
print_pdf(PATH_TO_FILE)
