Is this the right printer for you?

Who the Lexmark M1342 is actually for

Most equipment pages just tell you what a device does. Here's the honest version: when this machine is the right choice, when it's fine, and when you should look at something else. We offer equipment for every business need, but the right machine depends on your specific workflow.

Best fit

Pick this if...

  • You run a home office or small team of 1-10 people printing mono only.
  • You print 500-2,500 pages a month — the M1342 is sized for low-volume offices.
  • You need a single-function printer (no copy/scan/fax) and want to keep the desk footprint small.
  • You print short jobs all day and need 6.5-second first page out.
  • You're standardizing on Lexmark drivers and security across multiple sites and only need a print-only desktop unit.
Works fine

You'll be happy if...

  • You print up to 4,000 pages a month — toner economics get tighter past that with the 6,000-18,000 page Unison cartridges.
  • You want Wi-Fi — built in standard, no accessory needed.
  • You're cross-shopping the M3350 — M3350 jumps to 50 ppm, 4.3-inch color touchscreen, and 175,000 duty.
  • You only need wired — Gigabit Ethernet + USB 2.0 are standard.
Look elsewhere

Skip this if...

  • You need to copy, scan, or fax — this is print-only. Get the XM3142 MFP version (same engine plus scanner).
  • You need color. This is mono only — get a CS-series color printer.
  • You print over 4,000 pages a month — at that volume look at M3350 or M5255 for higher duty and lower per-page cost.
  • You want a touchscreen — M1342 has a 2.4-inch monochrome LCD only.
  • You print less than 200 pages a month — overbuilt for a personal printer; a Lexmark B2236 or similar is cheaper.
Full specifications

Every spec, no guessing

The Lexmark M1342 (29S0400) is a single-function mono laser printer for home offices and small teams of 1-10 that print 500-2,500 pages a month and want a compact desktop print-only unit with Lexmark's drivers and security. It prints at up to 42 ppm, runs a 1 GHz multi-core processor with 256 MB of memory, and is rated for an 80,000-page monthly duty cycle. Standard input is 350 sheets (250-sheet tray + 100-sheet multipurpose feeder), expandable with an optional 550-sheet tray. The 2.4-inch monochrome LCD handles basic settings; this is not a touchscreen device. Wi-Fi is built in standard, plus Gigabit Ethernet and USB 2.0. Print resolution tops at 2400 IQ. The replacement Unison toner cartridge prints up to 18,000 pages, which is what makes the per-page cost reasonable for an entry desktop. The thing buyers regret: ordering an M1342 when they actually needed copy/scan/fax. The XM3142 is the MFP version on the same engine — same speed, same chassis size, adds the 50-sheet ADF and scanner. If you need any of those functions get the XM3142 instead. For pure print at 42 ppm in a compact desktop with built-in Wi-Fi, the M1342 is the right call.
