Printer Memory and Expansion C-7

I/O Buffering

To allow the computer to continue working without waiting for the

print job to finish queuing, the printer uses a portion of its memory

(an I/O buffer) to hold jobs in progress. (If I/O buffering is off, no

memory is reserved for this function.)

In most cases, it is best to let the printer automatically reserve

memory for I/O buffering. (For each megabyte of memory added to

the printer, 100 kilobytes are reserved.)

To speed network printing, you might want to increase the amount

of memory reserved for I/O buffering.

To change the I/O Buffer setting:

1 From the I/O Menu, set

I/O BUFFER=ON

(page B-19).

2 Also from the I/O Menu, set

I/O SIZE

to the desired value.

Note When you change the I/O Buffer setting, all downloaded resources

(such as fonts or macros) will need to be downloaded again, unless

they are stored on an optional hard disk or flash DIMM.
