SYMPTOMS
After you sent a print job by using LPR to the TCP/IP Print Server, the TCP/IP Print server stops responding (hangs) and causes over 90 percent CPU usage in TCPSVCS.



CAUSE
This behavior occurs when the print job contains a value of 0x1B (ESC) in any of the following conditions:
 * At offset 0xFFF (4095).
 * As the very last character in a file.
 * As the only character in a file.

TCPSVCS has a routine to detect PCL or PostScript jobs, which goes into an infinite loop under these conditions.
