No-frills print to label printer help please

I'm writing a small app to print labels. Currently I'm targeting a 
Dymo LabelWriter 400 Turbo (a little USB printer) using a small 2.3" X 
4" label. I created a view in my app that uses that aspect ratio (I 
have yet to find out the printer's actual resolution) at about 315 X 
182. I draw a number of NSStrings in the view at different sizes and 
fonts.

My first pass at a print routing just calls

   [[NSPrintOperation printOperationWithView: mLabelView] runOperation];

and it prints, but presents the print dialog and shows a tiny version 
of my view in the center of the page with the wrong orientation (if I 
select "scale to fit paper size" in the Paper Handling section of the 
print dialog; if I don't select "Scale to fit paper size," it shoots 
out one blank label).

What I want is for my view to scale to fit the entire label, rotated 
to print wide, and i don't want the user to have to deal with the 
print dialog. There will be hundreds of individual labels being 
printed, but all in the same fashion. (There will be a pref for 
setting the printer/label size one time.)

I'm still reading through the printing docs, but maybe someone can 
point me to the specific things I need to look at to do this right? 
I'm sure there are many ways. For example, I could get the page size 
from the print info record, make the view that size, rotate my text 
and draw. But it seems like there should be an easier way to have my 
view rotated and scaled to fit the page (programmatically).

TIA,
