Can I hook up a usb printer to a computer that has no usb port? -

No. Unless it comes with another cable that is not usb. You should have at least one usb port on your computer. If that is the case you can get a usb attachment that makes one port 4 or 5 ports. If you have a computer with absolutly no usb port at all, I think its time you get a new computer. I dont think they have made any computers in the last 8 years without usb ports. http://www.pcconnection.com/IPA/Shop/Pro… something like this would help you get another usb port if you have at least one.

you can buy an adapter at a computer store

Some printers come equipped with both USB and parallel printer ports. You would need a printer cable to install. If no other port is available on your computer (a rarity) there is no other way that I know of short of getting a USB card bus to install on your computer.

no, you need a usb port in order to use a usb connection
