USB Printer Performance Under Windows 95

Normally sending output to a USB printer results in a print speed
slightly faster than that obtained using the highest baud rate of 115200
under RS-232. Our performance testing typically yields between 33 to
40 lines-per-second depending on other processes that takes place in
the terminal. Under Windows 95 the USB printer yields significantly
slow print speed with a maximum output of 25 lines-per-second. This
issue is due to the performance of the Window 95 USB Subsystem
which when released by Microsoft was not fully implemented, and not
optimized. Microsoft recommends upgrading to Windows 98 for USB
support. Our USB implementation allows the use of either Windows
98 or Windows NT to obtain the full speed benefits expected of USB.
