Our take
The Samsung ProXpress SL-M3320ND/XAA is a monochrome print-only printer with automatic duplex and wired connectivity. HP's U.S. guide maps the XAA model to SS365H, while Samsung's exact-model page lists USB, Ethernet, a 250-sheet main tray and a one-sheet multipurpose feed. Its rated speed is up to 33 ppm A4. The reviewed material does not document built-in Wi-Fi or a recommended monthly range, so neither should be inferred from sibling ProXpress models or from the maximum duty-cycle ceiling.
A wired office or workgroup that wants mono automatic duplex output and can use Ethernet without copy, scan or fax functions..
Skip it if scanning, copying, fax, built-in Wi-Fi or a verified recommended monthly workload range is required for the decision.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Automatic duplex supports two-sided output without manual page refeeding.
- Ethernet and USB provide a documented wired network or local connection.
- The 250-sheet tray plus multipurpose feed and optional expansion help with a shared print queue.
What to weigh up
- The exact model is print-only and cannot capture originals or send a fax.
- Built-in wireless networking is not documented for the SL-M3320ND/XAA.
- The 50,000-page maximum duty-cycle figure is not a recommended monthly volume.

What the features mean for you
Confirm the U.S. XAA identity
HP's U.S. support guide maps SL-M3320ND/XAA to SS365H, which ties the candidate to a U.S.-identified configuration. Samsung's exact-model support page supplies the feature details. Keep this model separate from nearby M3310, M3370 and M3820 printers, whose functions and suffixes differ. Check the device label before using a listing's title as proof; the historic model family alone does not establish which configuration is present.
Use automatic duplex for repeated packets
Samsung lists automatic duplex printing for the SL-M3320ND. The printer handles the page turn for a two-sided job, which can reduce paper handling for routine reports. The separate maximum duty-cycle ceiling is not a reason to treat every large queue as suitable. Plan the workload around a recommended range when one is available; the saved exact-model source does not provide that lower, routine-volume guidance, so the profile leaves it unknown.
Set up a wired connection
Samsung documents USB 2.0 and 10/100 Ethernet for this model. Ethernet supports a fixed shared queue; USB can serve one nearby workstation. Built-in Wi-Fi is not documented, so it should not be chosen for a wireless-required finder answer. Optional tray expansion is separate from connectivity and does not add Wi-Fi. Confirm network status and port function on a used device before deploying it to several users.
Match the paper path to the room
The base configuration lists a 250-sheet main tray and a one-sheet multipurpose feed, with an optional tray available. That arrangement handles a normal shared queue and allows a single special sheet without replacing the main stack. The input capacity does not establish the printer's ongoing recommended volume. If several users print long packets each day, compare reload frequency and consider whether the optional tray is actually included in a listing.
Keep the function set simple
The SL-M3320ND is a monochrome print-only model. It does not copy, scan or fax, so its fit depends on a separate device already covering paper intake and communications. This narrower design can work well in a department that sends digital files to one printer. Samsung's source lists up to 33 ppm A4; treat that as the maker's rating, not a measured promise for a particular document, driver or used unit.
What else to compare
The HP M209dwe adds built-in Wi-Fi and a documented 200–2,000 monthly recommendation for a lighter queue. The Lexmark MS821n is faster-rated and higher-volume but does not include duplex printing.
Before you buy
Does the SL-M3320ND/XAA print automatically on both sides?
Yes. Samsung lists automatic duplex printing for the exact SL-M3320ND model.
Does it have Wi-Fi?
Built-in Wi-Fi is not documented in the reviewed exact-model sources; Ethernet and USB are listed.
What monthly volume does Samsung recommend?
The saved exact-model sources do not establish a recommended monthly range; the maximum duty-cycle number is not a substitute.

The decision
Choose the SL-M3320ND/XAA for wired monochrome printing with automatic duplex. Its print-only role, missing wireless confirmation and unknown recommended workload should remain visible in the comparison.
