SYMPTOMS
A blank page is ejected by the printer following some LU3 print jobs.



CAUSE
In a print job ending with 0C 0D 19, or 0C 19, the form feed character (0x0C) is processed by SNA Print Server because it is not the last character in the data stream.

NOTE:

0C = form feed (FF)

0D = carriage return (CR)

19 = end of medium/end of message (EM)
