Our take
HP identifies product Q5957A#ABA as the LaserJet 2420d. Its 2400-series guide rates the 2420 family at up to 30 pages per minute on Letter paper and specifically says the 2420d includes the automatic duplex accessory. The guide also lists USB 2.0 and a parallel connection, a 250-sheet tray and a 100-sheet manual-feed tray. Ethernet is built into the separate 2420n and 2420dn configurations, not the d model. HP's reviewed guide does not establish a recommended monthly page range. This is a legacy direct-connected printer where the exact suffix and host support matter.
A direct-connected office that needs automatic two-sided monochrome printing and can verify legacy driver compatibility..
Choose another model if the printer must join Ethernet or Wi-Fi without optional hardware, copy or scan paper originals, or provide a stated monthly recommendation.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP maps Q5957A#ABA to the exact LaserJet 2420d product configuration.
- The d model includes automatic duplex and is rated up to 30 ppm Letter.
- USB and parallel connections support direct printing, with separate standard and manual-feed trays.
What to weigh up
- The d model does not include the embedded Ethernet server found on the 2420dn.
- The reviewed source gives no recommended monthly workload range.
- This older printer needs a current driver and individual-unit condition check.

What the features mean for you
The d suffix is the duplex configuration
HP's guide distinguishes the 2420d from 2420, 2420n and 2420dn models. It says automatic duplex is included with the d and dn variants, while the n and dn suffixes identify embedded JetDirect networking. The exact product page maps Q5957A#ABA to the 2420d, so the buyer can check a label against the article rather than relying on a broad 2420 family title. This distinction is essential: the d model provides automatic two-sided printing but does not become the networked dn model because the names are similar.
Automatic duplex suits recurring two-sided output
The built-in duplexer can turn supported sheets automatically, avoiding the manual stack refeed required by a simplex model. That helps with reports, internal forms and multipage documents when users regularly select two-sided printing. HP notes supported automatic-duplex paper sizes in the guide, so special stock should be checked before assuming it can use the same path. Manual duplex is also described for the series, but automatic output is the meaningful distinction for a busy routine. Test the duplexer on any used unit because the product specification does not establish its present condition.
Rated speed is not a workload recommendation
HP lists the LaserJet 2420 family at up to 30 pages per minute on Letter paper. That offers a comparison point for stated print speed, not a monthly capacity promise. The reviewed HP sources do not provide a recommended monthly range for this exact configuration. Keep both workload values unknown and do not substitute an upper duty-cycle figure or cartridge yield. If predictable sustained volume is a purchase must-have, use a model whose manufacturer publishes a recommended band. Otherwise, compare the actual routine with the printer's paper handling, connection method and maintenance needs rather than with an unsupported estimate.
USB and parallel mean a direct setup
HP documents USB 2.0 and a parallel connection for the 2420d, with a single EIO expansion slot. The user's guide lists the embedded JetDirect server only for the n and dn variants. The d configuration therefore fits a workstation or a compatible print-sharing arrangement through direct interfaces; it does not provide standard built-in Ethernet or Wi-Fi. Check that the intended computer and print server can use a suitable driver and physical cable. An optional network card on a specific used unit must be verified by part and test before it changes this assessment.
Two trays help separate ordinary and special jobs
The guide lists a 250-sheet input tray and a 100-sheet manual-feed tray for the 2420 series. The main cassette can hold recurring office paper while the manual feed supports smaller alternate jobs without replacing the standard stock. HP also describes an optional 500-sheet feeder, but that should not be assumed to accompany the exact offer. Check tray movement, paper pickup and the duplex path during inspection. Capacity can reduce the number of interruptions for normal printing, while the missing monthly recommendation leaves the intended sustained workload a separate decision.
Plan around a legacy device, not an assumed listing
The HP guide and U.S. product page establish a configuration, not the state of a printer for sale. Verify the Q5957A#ABA nameplate, print a sample page, test USB and parallel communication, and confirm duplex operation. Check current host support before building a shared queue around an older driver model. The article does not infer toner remaining, maintenance history, warranty, current price or supply availability from the historical candidate. A buyer who needs a modern wireless path or a documented page range should prefer a newer product; this model makes sense only when its direct connection and duplex role are enough.
What else to compare
Choose the 2420dn if its documented embedded Ethernet is needed, or a newer model if Wi-Fi and current driver support are priorities.
Before you buy
Does the 2420d include automatic two-sided printing?
Yes. HP's guide says the 2420d includes the automatic duplex accessory.
Does the 2420d have Ethernet?
The guide lists embedded JetDirect Ethernet for 2420n and 2420dn, not for the 2420d configuration.
What connections are documented for the d model?
HP documents USB 2.0 and a parallel connection for the LaserJet 2420 series.
What monthly volume does HP recommend?
The reviewed HP sources do not state a recommended monthly range for the exact 2420d.

The decision
The LaserJet 2420d combines legacy mono output with automatic duplex and direct connections. Its missing Ethernet and workload guidance define its limits.
