Rephrasing the question -- where in that chain does the translation of
PDF to something the printer can print occur?  I'm pretty sure that this
printer (Dell A10) is not a Postscript printer, so the PDF is not being
translated into PS.  As I understand it, the job of the printer driver
is to forward the data sent by the application to the printer
(ie. manage the hardware).  Therefore, the translation of PDF to
something that the printer can print either occurs in the application
(ie. Acrobat or GV) or in the printer (unlikely).  What am I missing?
