Our take
HP's U.S. product page identifies the LaserJet 4100dtn as product C8052A#ABA and marks it discontinued. HP's 4100 series guide separates the DTN configuration from the base 4100 and the 4100n: the DTN includes 32 MB of memory, a JetDirect 10/100Base-TX card, a 100-sheet tray, two 500-sheet trays, and a duplexer. Those included parts make the suffix important. A recommended monthly range is not established in the sources checked, and the page describes original specifications rather than the condition of any used unit.
A buyer evaluating a used legacy printer who needs wired Ethernet, automatic duplex, and the 4100dtn's included tray configuration..
Avoid it if you need a current product, built-in Wi-Fi, copy and scan functions, or a manufacturer-stated monthly workload range.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The 4100 series guide identifies automatic duplex and two 500-sheet trays as part of the 4100dtn configuration.
- HP associates the exact C8052A#ABA product with a JetDirect 10/100 Ethernet card.
- The 100-sheet multipurpose tray adds a separate path alongside the two main trays.
What to weigh up
- HP marks the 4100dtn discontinued, so current software and service support need checking.
- A recommended monthly page range is not established in the reviewed exact-model materials.
- A used listing may omit DTN trays or the duplexer unless the included hardware is verified.

What the features mean for you
The suffix separates a specific office configuration
HP's guide distinguishes the 4100dtn from the LaserJet 4100 and 4100n. The DTN version is documented with 32 MB of RAM, a JetDirect 10/100Base-TX card, two 500-sheet trays, a 100-sheet multipurpose tray, and a duplexer. These are configuration facts, not accessories to assume from a generic 4100 family listing. The product page maps the exact 4100dtn to C8052A#ABA and marks it discontinued. Verify that part number and the hardware shown in an offer before comparing this model with either sibling.
Two-sided printing is standard for the DTN
Unlike the released 4100n profile, the 4100dtn guide lists a duplexer in the model configuration. Automatic two-sided output is therefore an intended standard capability of the DTN, not an optional feature borrowed from another family member. Duplex can reduce manual handling for recurring reports, although it does not determine paper compatibility or print cost. Check the guide for media limits before sending specialty stock through the unit. A resale photograph of the internal path and exact label helps confirm that the component has not been removed.
Three trays favor a longer shared queue
The 4100dtn's two 500-sheet trays plus a 100-sheet multipurpose tray create 1,100 sheets of documented standard input. Separate trays can keep common stocks loaded and reduce interruption when a network printer serves several users. The multipurpose tray provides a distinct path for supported alternate media. This capacity is different from a compact single-tray personal printer, but it does not prove a particular used machine includes every cassette. Inspect the unit, confirm paper-size support, and ask which trays are included before selecting the exact offer.
Ethernet is documented; Wi-Fi is not established
The guide identifies a JetDirect 10/100Base-TX network card in the 4100dtn configuration. This supports a wired office connection where an Ethernet drop is available and a printer queue needs to be shared. The reviewed HP sources do not establish built-in Wi-Fi, so a wireless requirement should lead to a different documented setup. Network compatibility also depends on current hosts and drivers; a historical port specification does not prove that a particular secondhand unit can be configured with today's devices. Confirm the intended connection before purchase.
Discontinued status changes the purchase checks
HP marks the 4100dtn discontinued. That does not describe the remaining life of a particular unit, but it makes software, consumables, maintenance history, and return terms practical questions. The exact-model sources do not provide a recommended monthly range, and a maximum duty-cycle figure must not become a routine target. Ask about the page count and sample output, verify the duplexer and all three input paths, and confirm the C8052A#ABA label. Those checks determine whether this legacy configuration still fits a current office.
What else to compare
Consider a current mono network printer when driver and support continuity matter more than the 4100dtn's large included paper path.
Before you buy

Does this configuration include Ethernet?
HP documents a JetDirect 10/100Base-TX card for the 4100dtn; built-in Wi-Fi is not established.
What monthly workload does HP recommend?
The reviewed sources do not provide a recommended monthly range for this exact model.

The decision
The 4100dtn is distinct from the 4100 and 4100n because its documented configuration includes duplex and two 500-sheet trays. Its discontinued status and unknown guidance call for careful unit verification.
