WORKFLOW
Concurrency or Contention?
MFPs, by their very nature, are designed to handle
multiple tasks, acting as the printer, copier, scanner, and
even fax machine. BERTL looks at how these tasks affect
each other.
In BERTL’s concurrency test, a large print file is submitted
for printing. When spooling has completed, the rate at
which pages are output is measured. The BERTL analyst
then carries out various tasks such as scanning in a copy
job, to see if the print output rate is affected.
Batch Printing
Batch Printing: In many situations, people are often faced
with multiple files that need to be treated as a single print
job. There are two main reasons for this:
1) Multiple authors contributing to a single document
2) Collated sets comprised of multiple individual
documents.
These two workflow scenarios put MFPs and printers to
task, as they demand more than just the ability to spool,
RIP, and print a file as fast as possible.
Network Workload
Network-printing devices may often face a queue of jobs
stacked up for processing during busy periods of the day.
During BERTL’s network workload tests, analysts queue a
series of jobs at a paused print driver. The purpose of the
test is to illustrate how well a device handles a stream of
jobs and how the queue’s make-up can have a major
impact on a device’s performance. BERTL is not trying to
suggest that a series of jobs is an example of a typical
office application, as this would be misleading.
