Common law (also known as case law or precedent) is law developed by judges, courts, and similar tribunals, stated in decisions that nominally decide individual cases but that in addition have precedential effect on future cases. common law system is a legal system that gives great precedential weight to common law, so that consistent principles applied to similar facts yield similar outcomes.
I ran into an issue with a printer cable, IEEE1284, that was over 6 feet, and it would not work on an OS/2 operating system. The docs for OS/2 stated that 6 feet was the maximum length the printer cable could be for a parallel port connection.
The first step to adding a printer is to make sure the USB cable is properly connected to both the computer and the printer, and that the printer is plugged into a power outlet and turned on. Once you have physically connected the printer and turned it on, it should be recognized by your Mac.
