Here's what I think are the reasons:
(1) Getting the defaults from the printer's PPD (note that the CUPS
admin
    may configure default settings different from the delivered
settings).
(2) Evaluating a set of job attributes - such as duplex printing - the 
    implementation of which depends of what the PPD defines.
(3) Handling collated copies - depending on the capabilities of the 
    respective printer (some printers can do collated copies by
themselves,
    others, like many desktop machines, need the print job repeatedly
fed
    in for every copy).
