Printer Features
Some of the important features of the HP LaserJet 4, 4 Plus, and
LaserJet 5 printers are described below.
Page Protection (HP LaserJet 4 only)
Note
The default is PAGE PROTECT=OFF*. Unless you
frequently get 21 PRINT OVERRUN messages, you
may not need to set a value for page protection.
Page protection reserves additional memory for the page image
process, allowing the printer to create an entire page image in
memory before paper starts through the printer. The memory
required for page protection is dependent upon the resolution
selected: a 600-dpi page can take 4 times as much memory as a
300-dpi page. If you use page protection, set it for the size you
expect to use most often. Be sure you have sufficient installed
memory for the option you select. Complex graphics and
PostScript applications also require more memory than is
included in the standard printer configuration.
Note
Unlike earlier HP LaserJet printers, page
protection and resolution can be set regardless of
memory installed in the printer. Be aware that
setting page protection ON will decrease the
amount of memory available for other memory
dependent features.
