Draft mode
Depending on which printer driver is used, selecting draft or
EconoMode from the printer driver allows the printer to use
approximately fifty percent less toner, extending the life of the toner
cartridge.
MEt
HP MEt effectively doubles the standard memory through a variety of
font and data-compression methods.
Enhanced I/O
The Enhanced I/O feature allows printer memory to be used for
storing data received from the host computer. When Enhanced I/O is
enabled, you can send more data to the printer in shorter amounts of
time, which allows you to return to your application sooner. Enhanced
I/O has the following options:
!
Auto—allows the printer to use Enhanced I/O memory allocation
to increase the speed of data transfer from the host computer to
the printer, if necessary. The default setting is Auto.
!
Off—uses the minimum amount of printer memory for storing
data sent from the host computer.
!
Page Protect—allows the formatter to create the entire page
image in page buffer memory before physically moving the media
through the printer. This process ensures that the entire page will
be printed. The default setting is Auto.
Page complexity (ruling lines, complex graphics, or dense text)
can exceed the printer’s ability to create the page image fast
enough to keep pace with the image formation process. If Page
Protect is disabled and a page is too complex, the page might
print in parts (for example, the top half on one page and the
bottom half on the next page). Some print-data loss is likely in
these instances, and the printer will display an error message.
