what method do you use to create the standard letter size documents? ReportLab
has both page oriented and document oriented mechanisms built in.
If you use a Canvas ie page oriented then it's possible to change the page size
that the canvas will use.
from reportlab.pdfbase.ttfonts import TTFont
from reportlab.pdfbase.pdfmetrics import registerFont
from reportlab.pdfgen.canvas import Canvas
from reportlab.lib.colors import green
c = Canvas('helloworld.pdf', pagesize=(300,500))
c.drawString(100, 200, u'Hello World')
c.drawString(100, 300, u'Hello World')
if you use the document oriented layout then page sizes are normally determined
by a page template so you have to switch the template before the next page throw
