LaserWriter 16/600 PS: Technical Specifications

Basically, you have two physical connection methods to choose from:
a) Network over the Ethernet port. You will need an adapter (such as the Apple Ethernet Twisted-Pair Transceiver Model M0437) for RJ-45 cabling.
b) Directly/locally through the parallel port (via a USB-to-parallel adapter).
See the above manual for details.
A problem with relatively modern operating systems like Windows 8.1 can be to find suitable print drivers. The LaserWriter 16/600 PS is capable of handling both PostScript Level 2 and PCL5. If necessary/possible, look for and try a generic driver among the ones supplied with the operating system.
