The specifications for all printers on the market are based on ideal
conditions. In the case of Apple's laser printers, the assumption is that
a page has already been downloaded and imaged by the I/O board. In other
words, eight copies of a one-page document print in one minute, if you
start the clock when the first page is picked out of the paper tray. An
eight-page document prints slower, as each page must be downloaded and
imaged before being put on paper.
