normal processing of incoming jobs resumes.

3K to maximum
size allowed
User specifies the Parallel Buffer size. The maximum size depends on the 
amount of memory in your printer, the size of the other link buffers, and 
whether Resource Save is set to On or Off. To maximize the range for the 
Parallel Buffer size, disable or reduce the size of the serial, infrared, LocalTalk, 
and USB buffers.
