SPECIFYING INPUT PARAMETERS
XEROX DOCUPRINT 180 LPS PDL REFERENCE 4- 57
DJDE processing
Printing is controlled through parameters from the user-defi ned JDE
file which may be dynamically modified by dynamic job descriptor
entries. DJDEs are user created and are processed by the LPS as
part of the print data from the host machine. The chapter “Specifying
dynamic job descriptor entries (DJDEs)” defines their format and the
PDL statements necessary to let the system know they are part of the
input data.
Print-and-skip carriage control commands which are associated with
online DJDE records are treated as skip-immediate carriage control
commands. If the LPS is not at the channel specified, a skip occurs;
but if it is already there, no skip occurs unless the last command
received with a data record was a print-without-spacing command.
Print-and-space carriage control commands associated with DJDE
records are ignored.
Nonprint files (for example, font files) can be downloaded from the
host using the FILE DJDE.
Online optimization
The OPTIMIZE parameter of the VOLUME command allows the user
to select options for enhancing online throughput.
Copy-sensitive copy modification entries (CME)
Copy modification entries (CMEs) which are copy sensitive (that is, a
copy range has been specified on the MODIFY param eter of the
OUTPUT command) are ignored online since the data is not
automatically available multiple times. To produce copy-sensit ive
output, the user transmits data the number of times the data needs
to be modified. Thus, if six copies of a report are desired and one
CME applies to copies 1 through 4, and another CM E applies to
copies 5 and 6, the report should be transmitted from the h ost system
twice. The first transmission contains a copy count of 4 with CME1
specified, and the second transmission contains a copy count of 2
with CME2 specified. As an alternative, the application may be
successfully printed with only one transmission by using copy-
sensitive forms. Refer to the FORMS parameter of the OUTPUT
command in the “Specifying output parameters” chapter.
Report separation
Report separation is defined in terms of banner page detection or
other user-defined processing criteria. Logically separated reports
are physically offset from one another in the output bins. The two
logical processing commands which can be used to control online
report separation are BANNER and RSTACK. Refer to the chap ter
“Using logical processing commands.”
