I am looking for a brandname Intek 21 and model # tk9902 windows xp driver.

jharding...

There seems to be some confusion about the model number.
An Intek21 product is listed on the Advanced Tech Lab site
as MFR P/N (Manufacturer's Part Number) TK9902:
"PCI IEEE 1284 Bi-Dir. Parallel Port EPP/ECP/BPP/SPP Intek21"
http://www.atlcomputers.com/Parts-Controllers.htm

But the product which fits that description on the Intek21
site is the PCI HighSpeed Parallel Port card with the 
Part Number TK-P01E12:
- Conforms to IEEE 1284 parallel port standard
- Supports both DOS and Windows applications
- Supports data transfer rates up to 2MB/sec
- IRQ sharing feature eliminates IRQ conflict
- Supports EPP/ECP (PIO mode), Bi-directional Parallel Port
  (BPP), and Standard Parallel Port (SPP) modes

...and 'TK9902' shows up under 'Specifications' on that page:
- Regulatory Approval(s): FCC Class B (DoC) - TK9902
- Port type: Parallel port + One ECP/EPP parallel port +
  Conforms to IEEE 1284-1994 parallel port standard

The Intek21 site has the PPCI (Parallel PCI) drivers on 
this page:

The direct link for the Windows XP driver is:
