Page Protect
Page complexity (rules, complex graphics, or dense text) may 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 may 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.
Page Protect allows the Formatter to create the entire page image in page buffer memory before
physically moving the paper through the printer. This process ensures that the entire page will be
printed. Page Protect applies only to PCL printing. The default setting is Auto.
PJL overview
Printer Job Language (PJL) is an integral part of configuration, in addition to the standard Printer
Command Language (PCL). With standard Centronics cabling, PJL allows the printer to perform
functions such as:
l Two-way communication with the host computer through a Bi-directional Parallel connection. The
printer can tell the host such things as the control panel status.
l Isolation of print environment settings from one print job to the next. For example, if a print job is
sent to the printer in landscape mode, the subsequent print jobs print in landscape only if they
are formatted for landscape printing.
