I want to know that whether DB-25 male or DB-25 female connector can be used for parallel port interfacing?? Would there any difference between the two??
If you don't know the difference between male and female, you've been leading a sheltered life.
The standard parallel connector on a PC is a DB-25 female. You obviously need a DB-25 male to interface to that.
Of course most new computers don't have either the parallel printer or the serial RS-232 port, only the USB. But you can buy adapters that go from USB to either.
