I/O Buffering (HP LaserJet 4 Plus and 5 only)
I/O buffering allows the user to allocate printer memory to hold
the job while it prints, freeing up the host system sooner, like a
print spooler. The standard printer has approximately 10 KBytes
of memory allocated to I/O buffering and an additional 100
KBytes of memory is assigned to I/O buffering for each 1 MByte
of memory added to the printer.
If the printer has a minimum of 6 MBytes of memory installed
(12 MBytes of memory for a printer with a duplex option), the I/O
buffer size can also be adjusted from the control panel. Three
settings exist for the I/O buffer; AUTO (default), ON, and OFF.
AUTO sets the printer’s I/O buffer to a minimum value that is
determined by the total amount of memory that is resident in the
printer. Setting I/O buffering to ON allows the user to set the I/O
buffer size from the front panel. Setting the I/O buffering to OFF
disables I/O buffering .
Note
When you change the I/O buffer setting all
downloaded resources are deleted.
