I bought a HP 6122. It has provision for either USB or parallel
connectivity.
I would like to conserve one of my two USB connectors (at my computer) for
other purposes.
Is there any disadvantage to using the parallel connector instead of the USB
connector?
There is no consumer level printer that can use data faster than any
(current) printer port can send it, so all (other) things being equall,
use whatever port you choose, your printer will work just as well on
either.
I have read some listings that say "This printer requires USB 2.0".
Those printers are mostly printers with card readers built-in and the
2.0 requirement is (probably) tied to the card reader portion of the
printer.
Printers dont use data very fast... Witness the speed your computer can
get a picture on the screen. Thats the speed the computer can get the
data.
Now witness the speed you can view a picture from a card reader. Thats
the speed of the port you are using.
Now print that picture.... Takes longer right??? Thats the speed of your
printer driver/printer combination, they WONT out run even a USB 1.0
port.
