Our take
The Lexmark E450dn is a monochrome, single-function office printer whose most useful strengths are automatic duplex, wired connectivity and a published recommended range. Lexmark lists up to 35 pages per minute, Ethernet 10/100, USB 2.0 and parallel, with a 250-sheet standard input and recommended monthly volume of 1,500 to 6,900 pages. It is not a wireless printer in its base form; Lexmark identifies an external wireless print server as an accessory. This older model can suit a stable wired queue, provided the organization verifies the exact unit, drivers and supplies before committing.
A legacy wired office queue that needs mono duplex printing and can verify driver and supply compatibility..
Skip it if built-in Wi-Fi, color or multifunction features are required, or if the office needs a current platform with readily confirmed support and a lighter workload recommendation.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Lexmark documents integrated automatic duplex and up to 35 ppm monochrome output.
- Ethernet, USB 2.0 and parallel give the exact model multiple documented wired interfaces.
- The 1,500–6,900 page recommended range supports comparison for a regular office queue.
What to weigh up
- Wi-Fi is not built in and relies on a separate optional print-server accessory.
- The E450dn is a legacy printer; current driver, toner and maintenance fit are not established by its old specification page.
- A print-only design will not replace office copy, scan or fax equipment.

What the features mean for you
A dedicated monochrome queue
Lexmark describes the E450dn as a monochrome laser printer for business output rather than an all-in-one. That focus is sensible for a department that already has a copier or scanner and wants a separate printer for text pages. The product code 33S0700 is the U.S. part identified in Lexmark's source. The model does not add color or fax, and a seller title should not blur it with multifunction Lexmark products. Its relevance depends on a continuing need for black-only output and a compatible host environment for this older generation.
Automatic duplex is part of the design
Lexmark lists an integrated automatic duplex unit, so two-sided printing does not depend on a separate accessory for the documented E450dn. This can simplify recurring forms and reports by avoiding hand-turned stacks. The standard input capacity is 250 sheets, a reasonable reference for short office runs but not an invitation to infer a monthly duty recommendation. Confirm duplex operation on the exact offered printer, especially if it has been stored or serviced. Manual duplex is not separately documented in the reviewed record, so the comparison profile leaves that field unknown instead of guessing how the driver behaves.
Three wired connection paths
The E450dn lists Ethernet 10/100, USB 2.0 and a parallel interface. That can support a wired network queue or a direct connection, while parallel may remain useful only for a particular older host. Lexmark does not list built-in wireless for this configuration. The maker mentions an external wireless print-server accessory, but an add-on should not be mistaken for integrated Wi-Fi or assumed to accompany an offer. If wireless access is essential, identify the exact server and confirm whether it is supported and included. Otherwise, Ethernet is the straightforward shared-office option documented for the standard printer.
A published workload range for planning
Lexmark recommends 1,500 to 6,900 pages monthly for the E450dn. This provides a useful reference for a regular workgroup queue and is distinct from any maximum duty-cycle figure. Compare actual expected pages with this published interval, and consider whether a modern printer with support you can verify is a better fit if the volume is substantial. The up-to-35-ppm rating describes nominal engine speed, not the exact speed of a particular print job. The recommended range also does not tell you how much life remains in a used printer or consumable set.
Legacy support and parts are offer questions
Lexmark's specification supports a clear model-level comparison, but it does not establish present driver availability, cartridge stock, roller condition, fuser life, or the configuration of a marketplace unit. Confirm the 33S0700 label, inspect the printer, request a sample duplex page, check the wired network interface, and identify the included tray and consumables. For a host that depends on parallel, confirm cable and operating-system support before purchase. No current prices, stock or seller claims are inferred from the archived manufacturer listing, and no hands-on test is claimed.
Know what it will not do
The E450dn does not solve a need for color materials or paper capture. It is print-only, so copy, scan and fax must come from another device. A separate MFP may be more efficient where users routinely move between documents and output, though it adds features the print-only queue may not need. The E450dn makes the most sense when its exact wired interfaces, automatic duplex and workload guidance line up with a defined job. Treat the model as a candidate for that job rather than as a universal office recommendation, and include current compatibility checks in the buying decision.
What else to compare
For built-in wireless, compare a dw model with Wi-Fi listed as standard; for document capture, compare a mono fax MFP with an automatic duplex ADF.
Before you buy
Does the E450dn print on both sides automatically?
Yes. Lexmark lists an integrated automatic duplex unit for the E450dn.
Does it have Wi-Fi?
Lexmark does not list built-in wireless for the standard model; wireless uses a separate print-server accessory.
Which wired ports are listed?
Lexmark documents Ethernet 10/100, USB 2.0 and parallel for the E450dn.
What is the recommended monthly volume?
Lexmark recommends 1,500 to 6,900 pages per month for this model.
Can it copy or scan?
No. The E450dn is a print-only monochrome printer, so copy and scan require separate equipment.
