giving a PCI Card
This high performance PCI based EPP/ECP  parallel adapter card can be installed in a computer PCI slot to add one  parallel port to your PC, a cost-effective way to connect parallel  devices to the computer, with data transfer speeds of up to 1.5 Mbps (up  to 3 times faster than built-in parallel ports). The adapter card  supports EPP, ECP, SPP and parallel communications, and is simple to  install in virtually any PC.
Host Interface:PCI
 Data Transfer Rate: Up  to 1.50 Mbps Parallel Port
 Parallel Port Modes:  
EPP
ECP
SPP
BPP
 System Requirements: 
Computer
An open PCI slot
 Compatibility: 
Plug-and-Play
Parallel Printer
Scanner
CD-R/RW
