Our take
The SP 112 is a simple black-and-white laser printer for a desk where one computer can connect directly. Ricoh's U.S. brochure identifies the exact SP 112 part 407431, rates it up to 16 pages per minute on Letter paper and lists USB 2.0. Its small form is attractive when space matters, but the source also gives a 50-sheet paper capacity, which makes it a more limited choice for shared or frequent office jobs. The brochure does not establish automatic or manual duplex, wireless or Ethernet networking, or a recommended monthly print range. Treat it as a focused personal printer, and do not assume features from another SP-series model.
A compact desk needing basic black output from a nearby USB-connected computer, without a requirement for network sharing or multifunction features..
Choose another model if multiple users need network printing, if two-sided printing is important, or if you need a stated monthly-volume recommendation.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Ricoh identifies the exact 407431 SP 112 monochrome laser configuration.
- The printer is rated up to 16 ppm Letter and uses USB 2.0.
- A compact, print-only device avoids paying for scan, copy or fax functions that are not needed.
What to weigh up
- The stated 50-sheet paper capacity means frequent refills can interrupt a busy routine.
- The reviewed brochure does not establish built-in Ethernet or wireless networking.
- Duplex support and a recommended monthly workload remain unknown in the cited material.

What the features mean for you
Keep the job narrow: basic monochrome printing
Ricoh presents the SP 112 as a single-function monochrome laser printer, not an MFP. That makes it appropriate for invoices, text documents and other black output when scanning and copying already happen elsewhere. The exact part number 407431 helps distinguish it from related SP models that may have different paper handling or interfaces. For a one-person desk, avoiding unused features can also simplify setup. The trade-off is permanent: this machine cannot become the office's shared copy or scan station by changing a software setting. Match it to a deliberately limited print role instead of treating its low footprint as a substitute for multifunction capability.
Use the rated speed as context, not a throughput promise
Ricoh rates the SP 112 at up to 16 pages per minute on Letter paper. That provides a reasonable comparison point for occasional text output, but it is not a prediction for every file or from a cold start. Dense graphics, print settings and the computer connection can change elapsed time. The more important practical constraint may be paper capacity: Ricoh lists 50 sheets, so a stream of longer jobs can require repeated refilling. A buyer who shares the printer with several people should weigh that handling against the convenience of a small USB device. A higher-capacity printer may fit a recurring office queue better even when its desk footprint is larger.
USB makes the intended connection straightforward
Ricoh lists USB 2.0 as the standard interface for the SP 112. A direct cable connection suits a single nearby workstation and avoids planning a network address or wireless setup. The brochure does not identify built-in Ethernet or Wi-Fi, so those features are left out of the profile rather than borrowed from another SP-series model. If two or more people need a shared printer, check whether the intended computer, print server or operating-system setup can support a USB-only device before buying. The physical connection is simple, but it does not by itself promise driver compatibility with current systems or printer sharing across a workplace.
Do not assume duplex from the family name
The reviewed Ricoh brochure gives no firm statement about either automatic or manual two-sided printing on this exact SP 112 configuration. The finder therefore treats both modes as unknown. That distinction matters: a compact printer can look like a budget option for document packets, but without documented duplex support the user may need to print sides separately or use another process. Buyers who print double-sided regularly should verify the exact manual and driver settings or choose a model whose duplex function is stated clearly. The same caution applies to monthly workload: a 16 ppm speed rating and a 50-sheet tray do not answer how many pages Ricoh recommends printing each month.
Check the specific unit and its consumables path
For an older printer, published specifications describe the model but not the condition of a particular machine. Confirm the label says SP 112 and part 407431, inspect the paper feed path and print a test page before committing it to a routine. Ask what supplies are included and check that replacement consumables are available for the exact model from a source you trust; no current supply or price claim is made here. The 50-sheet capacity also means that placement should leave room to access the tray. An exact-model Amazon search helps identify listings, but a seller's photos and return terms determine whether an individual offer is suitable.
What else to compare
Choose a networked model for a shared printer or a documented duplex model for two-sided jobs; choose an MFP when scanning or copying is needed.
