Causation：

1.      Computer arithmetic speed can not keep up with transmission speed and printing speed.

2.      Use Printing port to transfer，the transmission speed cant follow the speed of printing.

Solution

1.  Replace faster computer, it is generally required to use a computer with Pentium 4 more than 1.7G.

2. Use 100M cable for transmission, and the speed  of network transmission is faster than that of the print port.
