Performance
Powerful wide-format color performer for workgroups
Printer performance is more than just a measure of pages per minute. Rather, printer performance is
the speed at which a printer can turn electronic files into printed pages. In addition to engine
speed, several factors affect the time it takes to print a job, including the use of special media,
computer download time, and printer processing time. The time it takes for your computer to
download a job to the printer, and for the printer to process the job, depends on the following
variables:
• The complexity and size of graphics
• The printer’s I/O configuration (network, USB, or parallel speed)
• The speed of your computer
• The network operating system and configuration
• Printer personality or language (such as PCL or PostScript)
A better performing printer leads to higher productivity in your workplace. You spend less time
waiting at the device, output appears more quickly, and network traffic is minimized.
Increase office efficiency
With HP’s in-line color printing, you can print professional, wide format, color documents as quickly
as printing black-only documents—up to 27 ppm letter (28 ppm A4) for a typical office document—
without compromising print quality. Most high-resolution technologies cause degradation in the
printer’s performance due to increased data transmission. They often require the user to install more
memory and may increase network traffic. But HP’s innovative technologies, including HP ImageREt
3600, achieve equivalent or better print quality without such tradeoffs.
To optimize performance, the HP Color LaserJet 5550 series printer features an inductive heat fuser
that virtually eliminates warm-up time. The printer’s first page out print speed from a Ready state is
up to 16.5 seconds. 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 no warm-up time, the printer
consumes less energy and realizes less wear on the engine.
HP’s native PDF printing
With the printer’s native PDF printing solution, a PDF file (or multiple PDF files) can be sent directly
to the printer from any device, without using PDF reader/converter software. The printer directly
renders PDFs to printed output, bypassing conversion processes used by other product-based
solutions, which increases printing performance and removes possible conversion errors. HP’s
native PDF printing enables driverless printing of PDF files, allowing printing from devices of all
types, such as mobile phones, handheld computers, PDAs, and notebook computers.
