Page Protection (HP 33449 Only)
For Page Protection to appear as a Configuration Menu option, at least 1 Mbyte of optional
memo~ mmt be installed
A page's compIexi@ (rules, vector graphics, or dense text) may exceed the printer's ability to create
an image and keep pace with the engine printing process. If a page is too complex, the page might
print in parts or only part of the page might print. In such cases, a 21 PRINT OVERRUN m essage
(signifying possible loss of print data) will appear in the display.
Page Protection reserves additiond memory for the page image process, Wowing the printer to
create the entire page image (in memory) before physidly moving the paper through the printer.
This ensures that the entire page will be printed. Page Protection can be set for LTR (letter), A4,
or LGLOegd) size pages.
Page Protection recotilgures the printer's memory each time the page protection level is changed.
For example, when Page Protection is enabled for letter-sized paper ("LTR'), 1040 ~ytes
of memory is reserved for the "image memory," which is memory dedicated for page-image
definition. When Page Protection is disabled (i.e., "OFF"), however, 848 ~ytes is released to user
memory and
191
~ytes is retained for the image memory.
With a 1 ~~e memory board intiled, user memory consists of 720 ~ytes of internal
(the
memov
that comes with the printer) user-available memory and the 1024 ~ytes of
added memory- a toti of 1,744 ~ytes. Table 3-8 Mustrates the available memory for various
configurations:
