As we mentioned, the HP LaserJet 2420dn is a monochrome (black and white)
laser printer with a maximum resolution of 1200x1200DPI. This is pretty much
standard for mid to high-end laser printers, and should suffice for
any text or graphic document you wish to print out.
On the inside, the HP LaserJet
2420dn ships with 64MB of onboard memory, expandable to 320MB by means of
a pair of 100-pin DDR-SDRAM slots, one of which is free.
A 400MHz Agilent processor handles onboard printing and serving tasks.
The printer can accept up
to two Compact Flash cards internally for adding new fonts.
Round back, the HP 2420dn features a trio of physical interfaces; a conventional IEEE
1284 Parallel port and USB 2.0 jack handle direct computer connections. A
10/100 Ethernet port provides network access to the HP JetDirect embedded
print server built into the printer for networked
installations.
An empty EIO (External I/O) port is also included which can be
used to add further HP accessories and interfaces. The JetDirect print server
has its own web-based interface which can be used to
configure the printer from any web browser on the network. The
server can send email alerts and even receive email
commands.
It has a variety of configureable alerts and status reports which it can deliver via email, simplifying
administration. Telnet and SNMP can also be used to manage the printer.
A variety of security options are available including passwords, encrypted
sessions and MAC Access controls. A full set of statistics and
printer status information is also available from this
interface.
