Our take
Lexmark's U.S. page identifies part 28S0500 as the E340, a monochrome laser printer rated up to 30 pages per minute. It lists USB 2.0 and a bidirectional parallel port, with no duplex feature available. Standard paper handling includes a 250-sheet tray and a single-sheet manual feed; a 550-sheet drawer is optional. Lexmark's page mentions a maximum monthly volume, but does not give a recommended monthly range. This is a legacy local printer, not a wireless network or two-sided office solution.
A legacy workstation needing local mono printing over USB or parallel and able to handle single-sided output..
Choose a newer network printer if Wi-Fi or Ethernet is needed, or a duplex model if two-sided output is part of regular work.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Lexmark maps the exact part 28S0500 to the E340 monochrome laser model.
- USB 2.0 and bidirectional parallel cover direct workstation and older local setups.
- A 250-sheet tray supports a basic paper reserve, with a separate optional 550-sheet drawer.
What to weigh up
- Lexmark says duplex is not available, so the model does not meet a two-sided printing need.
- The reviewed configuration does not list wireless networking or Ethernet.
- A maximum-volume figure is not recommended workload guidance, leaving monthly fit unknown.

What the features mean for you
A simple local monochrome print role
Lexmark identifies the E340 as a monochrome laser printer with a 30-page-per-minute rating. It prints black documents but does not offer copy, scan, or fax functions. That focused role can be useful for a workstation that needs local output and does not rely on a shared network. The exact part number 28S0500 matters because Lexmark lists related E-series configurations separately. Before choosing an old unit, check the label and ensure the computer still supports a suitable driver and connection path.
The manufacturer says duplex is unavailable
Lexmark's E340 page states that two-sided duplex printing is not available. Do not assume an automatic duplexer exists because a seller calls the model double-sided; the reviewed exact product record does not support that claim. A user could experiment with manual page reloading, but that is not a documented model duplex feature and can be cumbersome. For recurring packets, a printer with manufacturer-listed automatic duplex will save steps and make output order more predictable. This E340 is a fit only when single-sided pages are acceptable.
USB and parallel are the documented ports
Lexmark lists USB 2.0 and bidirectional parallel as standard ports. USB supports direct connection to a compatible workstation, while parallel may matter in older equipment setups. The reviewed exact page does not list built-in Ethernet or Wi-Fi. That limits the E340 as a shared office printer and makes network assumptions from a broad listing unsafe. Check the intended computer, adapter requirements, and driver support before purchase. A USB cable or parallel cable may not be included with a used offer, so verify what arrives with the unit.
Standard and optional trays need separate treatment
The standard E340 includes a 250-sheet input tray and a single-sheet manual feed. Lexmark lists a 550-sheet drawer as an optional paper input. That optional capacity should not be counted unless the drawer is physically included and compatible. The standard paper reserve can cover ordinary short print runs, but a shared queue may need more frequent refilling. Tray capacity also does not establish a monthly workload recommendation. Confirm the drawer and guides on the actual product rather than assuming a family photo depicts the offered configuration.
Do not substitute maximum volume for a recommendation
Lexmark describes maximum monthly volume for the E340 but does not provide a recommended monthly range in the reviewed specification page. Maximum duty cycle compares designed robustness; it is not an everyday target or a guarantee about an older machine. Keep the profile's recommendation endpoints unknown. Judge the model by the simple local use case, single-sided output, and available maintenance information. Ask for a print sample and page count if a seller has them, but do not treat those details as manufacturer workload advice or evidence about another unit.
What else to compare
Choose a networked mono printer when several users need access, or an automatic-duplex model when two-sided packets are a routine job.
Before you buy
Does the Lexmark E340 print automatically on both sides?
No. Lexmark states that duplex printing is not available for part 28S0500.
Does it have Wi-Fi or Ethernet?
The reviewed U.S. specifications list USB 2.0 and bidirectional parallel, not built-in wireless or Ethernet.
What monthly volume does Lexmark recommend?
The product page gives a maximum figure but not a recommended monthly range for the E340.

The decision
The E340 is a legacy local mono printer for single-sided output. Its simple ports and tray may fit an older workstation, but missing network and duplex features narrow its usefulness.
