i thought that printing with a USB connected printer was faster than LPT printing...

printer : hp 4345 mfp

is this normal?...

thanks
 
Are you connecting to a USB 1.0 port or is it USB 2.0? Lots of computers out there have USB, but unless you have a newer computer, the port you've plugged into may be USB 1.0, which runs at approximately 12 mbps, roughly equivalent to bi-directional IEEE 1284 LPT ports. As for USB 2.0, is should run as fast as 400 mbps, quite a difference.

Also, your problem may be what you're printing. If a simple page prints faster as a page heavily filled with graphics, then is it a question of program speed, connection speed or printer processing speed?
 
hi, yes, the computer is an HP7600 and is equipped with USB 2.0.

printing either simple or complex pages through USB is much slower than with an LTP cable.

thanks for your reply
 
And you're printing these tests to the same printer?
You may be having issues with the USB2 driver on that HP. Does a memory stick transfer files at the usual rate (as fast as it does on another machine)? You could also try installing this printer on another machine to see if it acts the same way.

In my experience USB (1 or 2) is not slower than LPT. dbMark's comments are accurate.
