Evaluating performance
What to measure
Different testing methods can be employed to gauge the performance of the HP LaserJet M1319f MFP. The
following tests are commonly used:
Click-to-drop The total print time, from the time the print command is issued, to completion of printing.
Return-to-application The time from initiating the print command, to the time when the computer is available for other
tasks.
Pick-to-drop The print time, from the instant the first piece of paper is picked up by the device, to completion of
printing.
First page out The time from initiating the print command to the completion of the first page.
Running the tests
Follow the guidelines below when measuring device performance:
• Be sure to measure the amount of time it takes to print a complete document. (For example, you might
print an eight-page document with company letterhead on the first page.)
• Perform each test three times to obtain an average. If the variances in the three tests are too much, discard
the results, check the system, and redo the tests.
• Look at each page to make sure all text and graphics printed correctly. Files that print significantly faster
on one device might not be printing correctly. Some devices drop complex graphics and images when
they are unable to process the whole job. Examine output to ensure that the entire document printed and
that it printed correctly.
• When comparing the performance of devices, look beyond the speed trial data and consider the
acceptability of the output. There are definitely tradeoffs in print quality, but as you review your results,
look at the samples and consider whether the quality meets your standards. For output quality evaluation
guidelines, see page 14.
