I have a Dell desktop computer with USB 2.0. I have been using Canon
i9900 ink jet printer which requires a USB connection (no parallel
connection).
I did not have any problem in the past with printing pictures using the
inkjet printer. A few days ago, I purchased a 4-port USB 2.0 (Ultra brand
from RadioShack) with power connection. I tested and confirmed that the
Ultra 4-port hub was indeed USB 2.0 compliant. Today, I connected the USB
cable to an Ultra port from the i9900 printer. The printer prints text file
without any problem but only printed about a half an inch of the top part of
image while printing images. I tested repeatedly and re-booting the
computer. Sometime, I uninstalled re-installed the i9900 printer driver. I
got the same problem. Eventually, I connected the USB cable to the front
USB port of the tower. Voila! Everything returned to the normal. No
problem with printing pictures. I am wondering whether USB cable for
printers should be connected directly to the port of CPU but not to USB
hub. I am wondering why. I was a bit surprised to see the limited
application of USB hub. Craig
