Yes, that is probably one part of the equation, but that depends very
much on which application did the printing. There are several ways to
print PDF files, but supposing Russell uses !PDF, then that is
definitely the case: Any JPEGs in the PDF file are expanded to sprites
by !PDF.
Things get much worse if the old PostScript 2 driver is used (instead
of PostScript 3). In that case, if the PDF file happens to contain
images with 256 colours or less you get several MB of data and the
printer taking ages to print. 30 minutes is not unusual in that case.
Things get even worse if you use the PostScript 2 driver and switch
the "Colour" option off. Then, the above applies to any image in the
file. My old Brother HL-1270 printer refused to print practically any
image that came from the PostScript 2 driver with "Colour" off.
