Output quality
High-quality output for all of your print, copy, fax, and scan needs
There are many different factors to consider when evaluating the overall quality of a product’s output. Print
quality is more than the number of dots per inch (dpi) that the device places on a page; a higher dpi rating
does not necessarily mean better print quality.
The HP LaserJet 3390/3392 AiO features a number of HP technologies, including HP Smart printing
technology,

to consistently deliver impressive results at an affordable price.
High-quality printing
Through innovative engineering, HP FastRes technology delivers outstanding print quality—at engine speed.
This means you get the high-quality output you have come to expect from HP without degrading
performance.
Because HP FastRes technology can represent each dot space as one of 256 levels of gray, the HP LaserJet
3050 AiO prints incredibly sharp text and graphics. As a result, the professional print quality obtained with
HP FastRes rivals that of competitive printers with higher dpi specifications—but without the performance
penalties.
HP FastRes is the default, out-of-the box print mode. However, for customers desiring the highest level of
print quality, HP ProRes 1200 provides true 1200 by 1200 dpi.
Professional copying, scanning, and faxing
• The color scanner converts printed material to digital information at high fidelity, with up to 1200 by
1200 dpi optical resolution, 24-bit depth, or up to 19,200 dpi enhanced resolution. You can make
impressive copies at up to 600 by 600 dpi, and send and receive faxes at up to 300 by 300 dpi.
• To ensure exceptional results, HP’s LaserJet Scan software includes scan-to application, multi-photo scan
with auto-detection of individual images, intelligent scanning to recognize the difference between text,
lines, and images, with optical character recognition for text editing capability, automatic scan
calibration, automatic image straightening, automatic cropping, and automatic image enhancement.
Ensured output quality with HP testing
Prior to its introduction, a new HP LaserJet All-in-One undergoes rigorous HP testing to ensure that it
provides consistent high-quality output. Tests are performed with a large sample of products through each
step of the design process, to be certain that the All-in-One measures up to HP standards. Throughout this
testing, HP discovers and resolves any issues that would compromise output quality. The result is a solid,
reliable product that produces consistent, excellent print throughout its life and the life of its supplies.
