Our take
Lexmark's U.S. page identifies the CS510de as part 28E0050, a network-ready color laser printer with standard two-sided printing. It rates the model up to 32 ppm in both black and color, lists Gigabit Ethernet and USB, and recommends 1,500 to 7,000 pages per month. This makes it a wired output candidate for a small or midsize office with a separate scanner or MFP. The CS510de does not copy, scan or fax, and wireless requires an optional adapter. Lexmark marks it discontinued, so current software and supply questions need separate attention.
A small or midsize office that needs color print output over a wired network, with automatic duplex and a published monthly range..
It is not for a color all-in-one workflow, built-in Wi-Fi without an optional card, or buyers who need a current-model service path.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Lexmark documents standard automatic duplex and up to 32 ppm black and color output.
- Gigabit Ethernet and USB support wired office sharing and direct use.
- The 1,500–7,000 recommended page band helps compare intended workgroup volume.
What to weigh up
- The CS510de is print-only, without copy, scan or fax hardware.
- Wi-Fi requires optional hardware rather than being standard on part 28E0050.
- The discontinued model's driver, supply and unit condition should be checked before purchase.

What the features mean for you
A dedicated color output point
The CS510de is a print-only color laser printer. This can be an advantage when a separate multifunction device already handles scans and copies, and the team wants a faster shared point for color documents. It is not a complete paper station, so it cannot replace an MFP for fax or originals. Lexmark rates color and black output at up to 32 ppm, but the published speed does not describe every color page or office job. Define the output role first, then decide whether the model's capacity and network fit justify a dedicated printer.
Automatic duplex is standard on the de configuration
Lexmark lists integrated duplex printing for the CS510de. The exact suffix is important because CS510 models with additional letters can bundle different trays or hardware. Automatic duplex helps with multi-page reports and documents that would otherwise require hand turning. It does not add duplex scanning because this is a print-only model without a document feeder. Confirm the label and part number on a used unit, and test the paper path and two-sided function. A general CS510 listing should not be assumed to include the same tray or options as every suffix.
Gigabit Ethernet is standard and Wi-Fi is an option
The CS510de includes Gigabit Ethernet and USB. That supports a wired shared queue and a direct local connection. Lexmark describes a wireless adapter as optional, so a base unit should not be credited with built-in Wi-Fi. A buyer who needs wireless placement should check the exact adapter's compatibility and whether it is actually included in the offer. For a managed office, confirm driver support and network policy before connecting an older printer. The original port specification is not a guarantee that an individual secondhand network card remains functional.
The recommended monthly band is a workgroup reference
Lexmark recommends 1,500 to 7,000 pages each month. This range can help compare the CS510de with personal models and larger production devices. It does not imply that a buyer must print at least 1,500 pages or that a unit with unknown service history will sustain the upper number. Paper capacity is 250 sheets standard, with optional trays available. Consider whether the included tray and actual monthly routine align with the office. Duty-cycle maximums and cartridge yields are separate values and should not replace this recommendation.
Check installed options and lifecycle before relying on it
Lexmark marks the CS510de discontinued. A specific unit may have optional wireless hardware, additional trays or memory, but the original model page does not establish what a seller's machine includes. Ask for the label, page count and included options; test color output, duplex, Ethernet and USB; and verify drivers, consumables and return terms. The exact product code 28E0050 separates the base CS510de from related configurations. This page and tagged Amazon search do not assert current offer stock, price, supply state or seller condition.
What else to compare
Choose a color MFP when paper capture is needed, or a standard wireless printer when adding an adapter is not acceptable.
