USB Type-B

USB Type-B is the roughly square legacy peripheral connector with beveled upper corners.

Also called USB-B printer USB Type B

Identify the device-side socket before ordering a printer cable.

Look for

Compare the socket outline with the taller SuperSpeed Type-B form. Inspecting both ends of an existing cable helps separate the connector name from the host connection.

What to look for

What the drawing does not prove

The difference shown is a manufacturer-described external shape, not a contact map.

The extra section changes plug-to-receptacle fit. Compare the actual device port before selecting a cable.

No fabrication dimensions, conductor routing, guaranteed fit or device approval. For electrical, power and optical interfaces, follow the original equipment instructions.

The useful distinction

Recognize it. Then verify it.

USB Type-B is the roughly square legacy peripheral connector with beveled upper corners. [C002A]

Legrand describes USB 3.0 Type-B device receptacles as accepting earlier USB 2.0/1.1 cabling; the taller USB 3.0 Type-B plug does not fit the earlier device receptacle. [C002C]

USB-IF compliance guidance requires Standard B-series connectors to use exactly four contacts; this count does not establish the USB generation or peripheral capability. [C002B]

Molex specifies 670688000 as a USB-B receptacle, 4 loaded circuits and 2 row(s), with mating-interface pitch 2.50mm. [C002W]

Identify the documented form

Separate legacy Standard-B from the taller SuperSpeed Type-B form.

  1. Look at the roughly square outline and beveled upper corners, then compare the complete opening with the taller SuperSpeed counterpart. S001 · S001
  2. Earlier cabling accepted by a documented newer receptacle does not make the taller newer plug fit an earlier receptacle. Keep plug and receptacle roles separate. S001

Keep this limit: The Standard-B contact count does not establish transfer mode or peripheral capability. S363

Make the next check

Read the peripheral manual for its exact Standard-B or SuperSpeed Standard-B connector.

Existing source inspection and AI review remain distinct from independent technical review. A matching form does not establish a safe connection.

Before you connect

What to check

  1. Confirm the socket is legacy Type-B, not SuperSpeed Type-B.
  2. Record the other end: Type-A and Type-C are different choices.
  3. Check device documentation for its USB mode.

Read the direction of the Type-B comparison.

The four-contact statement on this legacy record is scoped to USB 2.0. Earlier Type-B cabling may be accepted by the later USB 3.0 receptacle, but the raised USB 3.0 plug is not interchangeable in the reverse direction.
