This is not a Poppler issue. It has been an evince issue for a long time.

If you enable EV_SCALE_SHRINK_TO_PRINTABLE_AREA or 
EV_SCALE_FIT_TO_PRINTABLE_AREA, then ev_print_operation_print_draw_page 
calls _print_context_get_hard_margins, which provides the hardware 
margins of the printer.

The scaling is then calculated so the entire image fits inside the 
printer margins.

Sometimes you want this. Sometimes you don't - if your document is 
formatted at 8.5"x11", sometimes you want it to print at exactly the 
right scale (100%) onto 8.5"x11" paper, with the edges trimmed off 
(where printing is impossible).

evince should offer a choice. It does not, currently. Which is sad :-(
