Smaller machines have less room for large parallel port connectors. USB-to-parallel adapters are available that can make parallel-only printers work with USB-only systems. There are PCI (and PCI-express) cards that provide parallel ports. There are also some print servers that provide an interface to parallel ports through a network. USB-to-EPP ...
D-subminiature connectors are often used in industrial products, the DA-15 version being commonly used on rotary and linear encoders. DB-19 connector for an external floppy drive on a Macintosh 512K. The early Macintosh and late Apple II computers used a non-standard 19-pin D-sub for connecting external floppy disk drives.
For example, on the original IBM PC, a male D-sub was an RS-232-C DTE port (with a non-standard current loop interface on reserved pins), but the female D-sub connector on the same PC model was used for the parallel "Centronics" printer port. Some personal computers put non-standard voltages or signals on some pins of their serial ports.
USB 3.1, released in July 2013, is the successor standard that replaces the USB 3.0 standard. USB 3.1 preserves the existing SuperSpeed transfer rate, giving it the new label USB 3.1 Gen 1, [7] [8] while defining a new SuperSpeed+ transfer mode, called USB 3.1 Gen 2 [9] which can transfer data at up to 10 Gbit/s over the existing USB-type-A and ...
