Is this the right printer for you?

Who the Lexmark MS320/420 Series is actually for

Most printer pages just tell you what a printer 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 sell a lot of these for a reason, but the reason is not "every office."

Best fit

Pick this if...

  • You run a small office of 3-10 people that prints in black and white only and wants a clean wired install.
  • You print 500-3,500 pages a month — Lexmark's recommended monthly volume is 800-4,000.
  • You're fine without a touchscreen — most jobs come from the driver, the OLED handles paper jams and supply alerts.
  • You want auto duplex standard with a sub-$300 entry-level mono laser.
  • You want a small footprint — 10.2 x 15.7 x 14.7 inches and 31 lb fits anywhere.
Works fine

You'll be happy if...

  • You print 3,500-5,000 pages a month — the 50K duty cycle has headroom but the MS421dn at 42 ppm and 100K duty is a better fit at the top end.
  • You're upgrading from an older MS310 or MS415 — direct successor, supplies and trays carry forward.
  • You need expansion — the MS321dn takes optional 250 / 550-sheet trays up to 900 sheets total.
  • You're a wired-only shop — Gigabit Ethernet and USB 2.0 are all you need; no Wi-Fi, no extra accessories.
Look elsewhere

Skip this if...

  • You need color — this is mono only.
  • You need scan, copy, fax — print-only. The MX321adwe MFP is the version with a 50-sheet ADF.
  • You need Wi-Fi or wireless mobile printing — neither standard nor optional on this base model. The MS431dw adds Wi-Fi.
  • You need a touchscreen or fast first-page-out — operators used to a 4.3" e-Task panel will find the 2-line OLED slow for any menu-driven work.
  • You print over 5,000 pages a month — MS421dn / MS521dn is the right step up.
Full specifications

Every spec, no guessing

The Lexmark MS320/420 Series (standard config in this listing: MS321dn) is a small desktop monochrome laser printer for offices of 3-10 people printing 500 to 3,500 pages a month. It runs 38 ppm at 1200 x 1200 dpi with first page out as fast as 6.5 seconds and integrated duplex standard. Paper handling is 350 sheets standard (250-sheet tray + 100-sheet multipurpose feeder), expandable with optional 250 / 550-sheet trays up to 900 total. The 2-line monochrome OLED display handles supply alerts and basic config — not a touchscreen device. Connectivity is wired only: Gigabit Ethernet and USB 2.0 Hi-Speed standard. No Wi-Fi option on this base config. At 10.2 x 15.7 x 14.7 inches and 31 lb, the chassis is the same footprint as the MS521dn — same height, same width, same depth — for a smaller engine. The thing buyers regret: not stepping up to the MS421dn for $50-100 more. The MS421dn is the same chassis at 42 ppm with a 100,000-page duty cycle (vs 50,000 here) — better-suited to growing volumes if the office is on an upward print curve.

Supplies & consumables

Toner, yields, and what to actually reorder

The #1 question we get on this printer is "which toner do I buy?" Short answer: you have two cartridge options and a drum. Standard yield TN830 covers roughly 1,200 pages. High yield TN830XL covers roughly 4,500 pages and is the better value for most offices. Pick XL unless you print very little.

The drum unit (DR810) is separate and usually lasts 15,000 to 30,000 pages before it needs replacing. At a typical small office volume, expect to change it once every 2 to 4 years.

If you lease this printer through us, toner and drum are included. You never pay for supplies separately. That's usually the better deal once you add up real costs over 3 years.

What customers actually say

The 5-star consensus: "it just works"

Small sample size, high signal. The 3 verified reviewers picked this model to replace older inkjets or aging Lexmark machines. Common threads in the feedback:

  • ★ "Been using the MS320 in our small office for about two years now and it's been reliable. The print speed keeps up with what we need and the toner cartridges last longer than the Canon we had before. Occasional paper jam but nothing worse than other printers in this price range."
  • ★ "The MS420 does what it's supposed to do. Network setup was straightforward enough. My only complaint is the control panel feels a bit dated and the manual could be clearer on some settings, but overall it's a solid workhorse for a small business."
  • ★ "Bought the MS320 refurbished for home office use and couldn't be happier with the decision. Prints fast, quiet compared to what I expected, and the duplex feature saves paper. Haven't had any major issues in the first year."
