and describing the measured performance.

Testing was performed first with a USB
cable, then with the adapter set, connected
to an HP All-in-One printer (model C8180).
For wireless, the printer was placed in one
side of a meeting room, and files were sent
to print from a laptop, while sitting at the
other side of the room. In addition, testing
was performed for wirelessly scanning and
reading data from the printer’s built-in card
reader.
Two measurements, commonly used by the
print industry, were used: first page out
(measuring the time from sending the file
from the printer till the first page completes
printing) and Pages per Minute (PPM).
The table below shows that there was hardly any difference in user experience between wired and Wireless USB
connectivity. Also note that wireless performance remains the same when increasing the distance from 3 meters
to 8-10 meters.
