Limits, Constraints, and Considerations
♦ The VPC Filter is not supported on single-queue
systems such as the Nuvera Office Printer because
DocuSP does not support any filters on single
queue systems. The DocuSP GUI does not display
the VPC Filter settings on single-queue systems.
♦ The VPC Filter cannot be setup on a streaming
queue. The DocuSP GUI does not allow this
because crash recovery of filtered streaming jobs
does not work with the current architecture.
♦ The Generic Filtering Mechanism (GFM) does not
provide a method for stringing filters together;
therefore, only one filter can be applied to a queue.
♦ DocuSP’s job forwarding mechanism is not
supported.
♦ The VPC Filter is not supported in DocuSP Remote
Workflow (DRW).
Two-Stage Resource-Based Scheduling
DocuSP 4.2 provides a mechanism to:
♦ Determine all the resources required by a RIP-input
job before scheduling the job for printing.
♦ Allow the customer to choose between this new
scheduling mode and the existing modes.
♦ Prevent a job from being erroneously scheduled in
the event that some of the required media is
unavailable.
The scheduling modes that are available under
DocuSP 4.2 are:
♦ First-in, first-out (FIFO)
♦ Resource-Based (RBS)
♦ Enhanced Resource-Based (Enhanced RBS)
The default job-scheduling mode is RBS for all systems
except the Nuvera Office Printer. The default for
Nuvera is Enhanced RBS. RBS and Enhanced RBS
only apply to RIP-input jobs. Scan-input jobs (available
only on systems with a scanner) are not affected. Nor
are streaming jobs affected. Enhanced RBS is only
performed on PCL, PS, PPML, and PDF jobs. If
Enhanced RBS is in effect, all other jobs are processed
using RBS.
