Normally OS displays the detected port in Device Manager as communication port.
But in some cases USB<->COM works like a COM4 or COM5..in case of Telephone Modem Applications.
But for USB<->LPT, try to send serial data and scan your parallel datalines.
If you want to use complete signals like paper tray empty, line feed..you have to depend on cable manufacturers.
If you want LPT Port specific for Register Level Application, you can prefer PCI Add-on Card.
