That's because each browser has the a different page setup for printing,
margin, header & footer (including date, time, url, etc.).  You'll have
similar problems with PDF.  I have a few Word documents with 1/4 inch
margins saved as PDFs, via Acrobat Pro, to send out some folks.  When they
try to print w/o checking the configuration, Acrobat would just try to scale
and center, essentially reducing the overall size.  Either way, the user has
to check the configuration prior to printing just as they would have to set
the page layout in the word processor.  The only way I see around this is to
actually generate Word type document, where the user doesn't need to do
check the configuration.  Since Word format is proprietary, you'll might
some problems getting the code.

I too like to do things right the first time :)

IIRC, if you used em, it relies on each browser's font configuration.  So
you'll have to pt with !important.

Yup on the HP 2015 at 1200 dpi.  The only browsers that didn't print out
correctly (on Windows) are Chrome & Safari, both are web toolkit...  which I
can't seem to find the scaling on the print configuration.  Apparently, I'm
not the only person with the printing issue [1].   IE 8 (w/o compatibility -
shrink to fit off), Firefox 3.16 (shrink to fit off), and Opera 10.63 (fit
to paper width off and scale print to 100%)  have scaling capability.  All
have margins at 1/4 inch or .635 cm.  This is from my template a while back.

Anyway, we're totally off-topic :))  Perhaps we should take this off-list,
unless others are interested in this also.  Forgot to mention that with
this, there should be no waste as the user can specify to start printing at
which label #, counting left to right then top to bottom.  IIRC, Avery has a
lot of different address and return address labels size (I used to work
there a long time ago), ranging from 1/2 to 3 inches height.
