Our take
The HP LaserJet 4350n is a fast discontinued monochrome printer with a 55 ppm Letter rating, built-in 10/100 Ethernet, and 600 sheets of standard input. HP recommends 5,000–20,000 pages monthly, positioning it for a heavy office queue. The suffix is critical: the 4350n does not include a standard automatic duplexer, and an optional unit is required. Its original specification may suit a particular wired environment, but current unit condition, supplies, and service support are not established here.
A buyer considering a verified legacy wired printer for high-volume monochrome work who can accept optional duplex hardware..
Do not choose it if automatic duplex must be present in the base machine, if you need Wi-Fi or an all-in-one workflow, or if you require a current supported product.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP documents up to 55 ppm Letter and 52 ppm A4 monochrome printing.
- A 600-sheet standard input and 5,000–20,000 page recommendation target heavy office work.
- Built-in 10/100 Ethernet, USB, parallel, and EIO expansion are listed for the 4350n.
What to weigh up
- The n model does not include a standard automatic duplexer; a compatible optional unit is needed.
- HP marks the product discontinued, with current supplies, service, and condition unverified.
- The historical ASIN and structured candidate suffix remain unconfirmed as exact identities.

What the features mean for you
A fast printer for sustained mono work
HP rates the 4350n at up to 55 pages per minute on Letter paper and 52 on A4. It is a print-only monochrome model aimed at recurring office documents rather than color graphics or a multifunction desk. The published recommended monthly range of 5,000 to 20,000 pages reinforces that role. A speed ceiling is not a promise for every job, and a monthly duty-cycle maximum should not replace the recommendation. Start with the real queue and decide whether a large legacy printer is appropriate for the space and support available.
The n suffix does not include automatic duplex
The 4350n configuration has a 100-sheet Tray 1 plus a 500-sheet Tray 2, for 600 sheets of standard input. HP's series guide distinguishes suffixes and notes that automatic duplexing requires an optional duplex unit for this n model. That accessory must be verified and counted only when it is actually included and compatible. Do not infer the dtn model's duplex capability from a 4350 family listing. If automatic two-sided output is a hard requirement, confirm the installed option from the exact machine rather than relying on a seller's broad model-family title.
Wired interfaces cover a traditional office
HP lists built-in 10/100Base-TX Ethernet, USB 2.0, a parallel port, and two EIO slots. Ethernet supports a wired shared queue, while USB and parallel offer direct or legacy connection paths. The packet does not document built-in wireless for this exact model, so Wi-Fi remains unconfirmed. A current buyer should also check operating-system and driver support before choosing an old printer for a modern managed network. An EIO slot or external print server should not be represented as an included wireless feature without evidence about the individual configuration.
Paper capacity supports longer jobs
The 600-sheet base feed combines a 100-sheet multipurpose Tray 1 with a 500-sheet Tray 2, and HP lists further tray expansion separately. This provides more standard paper reserve than the M402dne's 350 sheets and may reduce refill interruptions on long jobs. Optional expansion is not part of the base machine unless a seller confirms that hardware. The 5,000–20,000 recommended pages per month is the better indicator of intended routine; capacity alone does not establish the suitability of any particular team's workload or prove operating reliability.
Model suffix and lifecycle need scrutiny
HP marks the 4350 series discontinued, and the saved packet distinguishes the 4350n from variants with other standard equipment. The candidate's structured code Q5407A#201 and historic ASIN B00064C3WS were not proven to identify this exact U.S. model. The tagged search therefore names the 4350n and HP product number Q5407A. Before buying, ask for the complete suffix and product label, installed duplex hardware, tray configuration, page count, toner details, and return terms. Check the present supply and service path separately; the original data sheet cannot establish that an old unit is supportable now.
A conditional choice for wired high-volume pages
The 4350n is worth comparing when an office wants fast monochrome output, a wired Ethernet port, and a 600-sheet standard feed. It is a poor fit for two-sided print jobs unless the optional duplex unit is installed. The Lexmark MS810dtn offers automatic duplex and 1,200 standard sheets, while the HP M402dne is a smaller duplex model with a lower monthly range. Those alternatives define why exact configuration matters: the question is not whether a family was powerful, but whether the offered unit's hardware matches the queue and support requirements.
What else to compare
The Lexmark MS810dtn includes integrated duplex and 1,200 sheets of standard input with a 3,000–50,000 page recommendation. The M402dne keeps automatic duplex in a smaller 350-sheet configuration.
Before you buy
Does the 4350n include automatic two-sided printing?
No. HP identifies the n configuration as lacking a standard duplexer; automatic duplex requires the optional unit.
How much paper is standard on the 4350n?
HP lists a 100-sheet Tray 1 and a 500-sheet Tray 2, for 600 sheets of standard input.
What monthly use does HP recommend?
The saved HP support specification lists a recommended range of 5,000 to 20,000 pages each month.

The decision
The 4350n can suit high-volume wired monochrome output only after the suffix, duplex accessory, condition, and supply path are verified. Without the optional duplexer, it does not meet an automatic two-sided requirement.
