Performance
Fast, fast, fast—get more work done in less time
Performance is more than maximum engine speed, measured in pages per minute (ppm). Rather,
performance should be gauged by the speed at which the device can turn electronic files into printed pages
or convert printed material into electronic information. In addition to engine speed, several factors affect the
time it takes to print a job, including the use of special paper, computer download time, and device
processing time. The time it takes for your computer to download a job to the device, and for the device to
process a job, depends on the following variables:
• The complexity and size of graphics
• The product’s I/O configuration (network or USB speed)
• The speed of your computer
• The amount of device memory installed
• The network operating system and configuration (if applicable)
• Printer personality or language (such as PCL or PostScript
®
)
Note Adding additional device memory may resolve memory problems, improve how the device handles
complex graphics, and improve download times, but additional memory will not increase maximum
engine speed (ppm rating).
A better performing product leads to higher productivity in your workplace. You spend less time waiting,
because output appears more quickly and network traffic is minimized. The HP LaserJet 3390/3392 AiO is
optimized for performance, print quality, and affordability; it completes complex jobs quickly and without
device failures.
Fast print and copy speeds
Increase office efficiency with print and copy speeds up to 22 ppm letter (21 ppm A4).

The product
features Instant-on Technology which uses an inductive heat fuser to virtually eliminate warm-up time from
both the Ready and PowerSave states. The product delivers the first page in less than 8.5 seconds letter/A4
when printing and less than 10.6 seconds letter (10.7 seconds A4) when copying. The predictive ready-to-
print algorithm processes jobs in parallel with printing and improves the first page out print speed over
time. Because there is little warm-up time, the product consumes less energy and realizes less wear on the
engine.
Productive faxing
Experience fast processing speeds of up to 33.6 kbps with the Super G3 V.34 fax modem and store up to
250 pages of important fax documents with 4 MB of fax page memory. HP LaserJet Fax software allows
you to send and receive faxes directly from your computer—even from applications like Microsoft
®
Word or
Excel—saving time, paper, and printing supplies.
