Our take
The HP LaserJet M4345xs is a monochrome multifunction device for a larger document workflow. HP's exact-model page lists print, copy, digital sending and fax functions, a 50-sheet automatic document feeder, output up to 45 ppm, and a recommended monthly range of 5,000 to 20,000 pages. It is a very different task profile from a small personal printer. The reviewed source does not settle the xs model's automatic-duplex configuration or clearly identify the standard network port, so those details remain open selection checks rather than assumed family features.
A high-volume black-and-white copy, scan and fax workflow where the documented 50-sheet ADF and monthly recommendation matter more than color or compact size..
Skip it if you need color, a compact desktop unit, a clearly confirmed automatic duplexer and Ethernet in the source record, or only occasional home printing.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- HP documents print, copy, scan and fax tasks for the exact M4345xs model page.
- The 50-sheet ADF can feed a stack of originals for copying or scanning.
- A 5,000–20,000-page recommended range gives a concrete high-volume planning band.
What to weigh up
- The reviewed exact-model page does not identify the xs duplex configuration clearly enough to require it.
- The standard network port is not itemized clearly on the saved exact-model page.
- This is a legacy large-format office device; current support, condition and service needs require checking.

Full review: how the features affect your choice
What the features mean for you
A monochrome document station, not a print-only unit
HP lists the M4345xs as a laser multifunction model with one black print cartridge and functions for printing, copying, scan-to-email or network folder, and fax. The extra document tasks change its role: staff can work with paper originals at the machine instead of routing each job through a separate copier or scanner. Color output is not part of the cited specification. HP lists fax on the exact model page, while the more detailed paper and interface configuration still needs inspection on the particular xs device before purchase.
Match the published workload band to the queue
HP rates the M4345xs up to 45 pages per minute and recommends 5,000 to 20,000 pages a month. The recommendation is a planning interval for a sustained office routine, not a promise about an old machine's present output or a speed guarantee for every job. It can help rule the model out for a low-volume desk where its large multifunction role is unnecessary. Do not replace the recommendation with the separate maximum-duty-cycle figure; that number describes a ceiling rather than ordinary target use.
A 50-sheet feeder changes handling for originals
The model-specific page lists a standard 50-sheet automatic document feeder. That allows a short stack of originals to pass through for the scanner and copier rather than requiring each page to be placed individually on glass. The source does not establish duplex scanning for the exact model, so do not assume that a double-sided original will be captured in a single pass. For a large office, confirm the feeder's rollers, paper path and actual scan workflow on the specific device, especially when it is being sold used.
Keep duplex configuration separate from the M4345 family
HP notes that advanced paper handling varies across M4345 models, and the reviewed page does not establish whether this exact xs configuration includes automatic print duplex. The xs suffix identifies a distinct product variant, but it is not permission to copy the duplex setting from the base M4345, an x model or another configuration. If automatic two-sided output is a hard requirement, ask for the exact product label and an HP configuration document or a test print showing the duplex unit. Until that is confirmed, the finder leaves duplex unknown.
Verify the network port and long-term fit
HP describes wireless as optional hardware and calls the model network-ready, but the exact-model page does not clearly name the standard port for the xs device. Confirm the rear interface and any Jetdirect equipment rather than assuming that network-ready means the listing includes a working Ethernet connection. Also check the device's page count, feeder, output condition, software support and service route. The historical model's specifications do not establish current supply availability, live price, the quality of a particular unit or compatibility with every current operating system.
Compare for your needs
Choose a model with an exact duplex and interface table if those are mandatory, or a smaller MFP when the queue does not need this monthly range.

Yes. The exact-model page includes fax memory and fax as a scan input mode.
Is automatic duplex confirmed for this xs configuration?
The reviewed HP page does not clearly map automatic duplex to the exact xs configuration, so verify the unit.
What monthly volume does HP recommend?
HP recommends a monthly page volume between 5,000 and 20,000 for the M4345xs.
