Well, I did that - I was already using the printMargins settings (72
all round) to calculate where on the card to put the field that
contains the print content, but at your suggestion at the last minute,
just before the actual print statement, I set them to all 0s without
going back and altering the position of the field. The result was (to
me) extremely strange: the printing worked properly, in that each
margin was now 1 inch (72 pixels). This also included the top and
bottom margins. In reality my particular printer won't print on the
whole paper surface, so margins of zero are meaningless. Thus I'm at a
loss to understand why it worked. Eventually I'll try it on the PC and
see if the thing behaves differently.
Thanks very much for the advice - I just wish I understood why it
worked. It seems to me pretty much like a bug in RR.
