HP Laser 4L driver for USB port

Not all USB adapters are the same, you need the one that is made for your printer, I would try a different adapter before going too deep, because when you plug it in your computer should see it even without drivers.

Try this first

Start/setting/control panel.
System
Hardware
Device Manager
Ports
ECP LPT1
Port settings

Check use any interupt assigned to port.
Check enable plug and play.
Check OK.

Restart the computer!

Try to print. Is everything ok? Then we're finished.

If not,

Start/Settings/printers right click properties. Go to advanced.

Check print directly to port.

Uncheck enable advanced printing features.

Try printing again.

You can download driver from here.
