  • I have a laser printer which has a 25pin male connector hard wired into it. I want to figure out a way to connect this printer to my laptop which has only a USB port available. Do you have any suggestions?
    • We have a USB to female 25 pin adapter that is made specifically to work with printers. As long as your printer does not have built in copy, scan, or fax functions it should work with it. The part is our USB to Parallel DB25 adapter, part SW-4518.

  • For the Part No: SW-1801, what is the pinout for pins 2 and 3? Does 2 go to 3 and 3 go to 2 or is it 2 to 2 and 3 to 3?
    • Here is the pinout: (9 pin > 25 pin) 1>8, 2>3, 3>2, 4>20, 5>7, 6>7, 7>4, 8>5, 9>22. So pins 2 and 3 do switch.

  • I need a port adapter. ( 9 pin male to 25 pin male ). Both ends of my adapter need to have pins on them.
    • If you want to go from 9 pin male to 25 pin male, the best solution we can offer is to purchase this male to female adapter along with a gender changer to conver the female serial end into a male connection.

  • Is there anyway to adapt a DB25 male cable to a DB25 female cable?
    • Certainly, if you need to change the DB25 male connection to a DB25 female, simply use one of our DB25 Gender Changers and you'll be able to plug the two cables together.
