Chapter 7 Using Page Level Recovery On LineJet Printers

Using Page Level Recovery On LineJet Printers

	The native mode spooler on MPE/iX 5.5 (and later) supports Page Level
	Recovery (PLR). PLR provides the ability to restart printing at any page of a
	document due to device problems or a suspended spooler. (Refer to the HP
	e3000 MPE/iX Native Mode Spooler Reference Manual for more information.)
	Clarification on how it is handled for LineJet printers is described below.
Note	One feature of the Printer Job Language (PJL) spooler is the ability to
	keep track of pages printed as a part of Page Level Recovery. On a paper
	jam or paper out condition, the printer control panel displays the page
	number counted.
	For Page Level Recovery to be operational, the printer must have a
	minimum of 4 MB Flash and DRAM memory; CMX Controller, Version 5.5
	or later; and be running Function Code, Version 356351, Rev. 2.07P or
	later. All of these requirements are satisfied with the LineJet and LP Series
	“C” and above models. However, LP Series “A” and “B” models require
	upgrading to gain Page Level Recovery functionality.
	There are three types of PLR that can occur, and all three use silent run
	techniques. That is, the data is sent to the printer and the printer interprets it
	but does not start actual printing until the printer reaches a target starting
	page specified by the spooler (e.g., the page following the last one printed).
	Restarting at a user-specified page number in a command
	Processing of a spool file can be suspended and then resumed. It can be
	suspended by using the spooler command with the suspend parameter
	or by using the suspendspool command. It can be resumed with the
	spooler command with the resume parameter or by using the
	resumespool command. When the spool file resumes printing, it can start
	exactly where it left off or at another specified page.
	For LineJet printers, the optional offset parameter in the spooler
	command can only be used to specify an absolute offset (i.e., absence of a +
	or – sign). When the offset parameter is not used, printing resumes where
	it stopped. When the offset parameter is used, a silent run (PLR) will occur
	up until the specified starting place.
Note	The CIPER protocol devices (e.g., C256x using the HP-IB interface) allow
	you to specify the offset parameter with the + or – sign. With spooled
	network printers such as LineJet printers, unpredictable results will occur if
	the offset parameter is used with the + or – sign.
	For example, to suspend spooling and to position 7 pages from the beginning
	of the spool file, enter the following command:
	spooler 6;suspend;offset=7
	In this case, the absence of a + or – sign indicates an absolute offset from the
	beginning of the spool file.
