That's to bad. I was hoping that the printer name could be retrieved.
Here's my thinking.
Since I believe that printing PDF's are now universal (tested printing on
windows and linux - I hope MAC's work the same way)
if sys.platform == 'win32':
os.system('print '+filenamewithpath)
elif sys.platform == 'linux2':
prnstr = 'lp -d %s %s' % (printername filenamewithpath)
os.system(prnstr)
else: ##Must be a MAC
os.system(string using what a MAC needs)
If the above worked then we would have a universal way to print PDF's from
within report writer. I'm not sure if os.system would be the best (maybe
popen() ) but you get the general idea.
Under Linux (also available on the MAC) there is pycups.py. Which uses the
CUPS lib to retrieve information on the printer queue. But is not part of
the standard available packages. To be honest I don't even know if MAC's use
CUPS to print.
import cups
c = cups.Connection()
printers = c.getPrinters()
Now with the list of printers. We create a dialog to select the printer and
pass the selection to the above print routine.
On the surface it appears simple. As you can see we could print the PDF's
generated from report writer and not just depend on forcing a preview to
allow printing.
