Dear Sandy,

Maybe my provider blocked unintentional an other e-mail from you but I
never saw the results of your tests for smoothness and tonality.
Can you tell me where I can find them ?
In a German magazine I found a test about the B9180.They wrote that the
printer makes most noise of all the tested A3 printers,used most power :
38 watt,but was by far the cheapest in printing.
BUT :THEY COULD NOT PRINT ON FILM !! Every time they tried to do that it
became a mess.They even advised HP to remove the word "transparantfolie"
(film) from their specifications ! (But they didn't specify what sort of
film it was,maybe it was film for an overhead projector.)What film did
you use for your tests ?
