Our take
Lexmark's U.S. record identifies part 26B0000 as the C543dn, a color laser printer with integrated duplex. It prints at up to 21 pages per minute, and Lexmark recommends 500 to 1,500 pages monthly. Standard USB and 10/100 Ethernet support direct or wired-network use. The C543dn is print-only; it is not a color MFP. Its lower recommended range can suit a small queue, but it should not be treated as a high-volume workgroup model merely because the maximum duty cycle is higher.
A wired color print queue for routine volumes within Lexmark's 500–1,500 page recommendation, where automatic two-sided output matters..
Avoid it when copying, scanning, fax, built-in Wi-Fi, or a routine monthly volume above 1,500 pages is required.

Full review: how the features affect your choice
What the features mean for you
A print-only configuration keeps the task narrow
Lexmark describes the C543dn as a color laser printer, not as a multifunction device. That makes it appropriate only when output is the task and users do not need a scanner or copier at the same station. The dn suffix identifies a duplex and network configuration; it should not be confused with models that add copy, scan or fax. If those functions are already covered elsewhere, a printer-only machine can avoid duplicating an unused workflow. Confirm part 26B0000 and the exact C543dn marking before matching the listing.
Automatic duplex is part of the dn model
Lexmark lists integrated duplex printing on the C543dn. This allows it to turn sheets during two-sided jobs, reducing the need to refeed pages manually. The feature is useful for reports and internal documents, but it does not add document-scanning functions. A paper-saving option should be evaluated alongside the actual stock and print routine; it does not guarantee a lower total cost. Ask for a duplex test on a used unit because the product specification cannot establish the condition of a particular feed path.
The network path is wired
Lexmark lists USB 2.0 and 10/100 Ethernet for the exact part. Ethernet can place the printer on a wired office network; USB is available for a nearby host. Built-in Wi-Fi is not part of the standard interface specification, so do not infer wireless from an optional Lexmark accessory or a photograph of a different C540-series model. Confirm the computer and network environment can use a compatible driver. The C543dn's listed ports and print-only design are the central configuration facts for a shared queue.
Stay within the recommended page range
Lexmark recommends 500 to 1,500 pages per month. The separate maximum duty-cycle number is not the same as routine workload guidance and should not be used to justify a sustained volume above that range. Color jobs can also differ in toner use from monochrome documents, but this review does not estimate consumable cost or present-day supply availability. Compare your ordinary monthly output with the recommendation and choose a higher-volume device if this printer would regularly exceed its stated band.
Check the part number and installed options
The manufacturer page ties part 26B0000 to the C543dn and lists automatic duplex, USB and Ethernet. Lexmark's C540 family sheet provides additional context, but neighboring models can have different speed, network or paper features. The article does not carry those sibling facts across to this exact C543dn. A used listing may omit a cable, show an optional tray or have wear; verify what is included and test the first-page output. Lexmark marks older models discontinued, so assess ongoing support separately.
Compare for your needs
Choose a color MFP if copy or scan is part of the routine, or a higher-capacity printer when expected volume exceeds the published range.
