Wireless Printing Problem

Hi Everyone,
I have a small home network setup consisting of a HP m8200n media center pc, running windows vista, HP a1230n media center pc running windows xp media center 2002 service pack 3, and an acer aspire 5102 notebook running windows xp media center 2002 service pack 3. The two windows xp machines are connected to my network by wirelesws adapters.

I have a lynksys wrt54gs wireless router and a Dlink DSM-G600 wireless network storage enclosure.

I have two printers one is a Brother MFC-465CN which is connected directly to my router. The other is a Brother HL1440 laser printer connected to my router by a netgear PS 101 parallel port print server.

My problem is that I cannot print to the Brother HL1440 by wireless. All three computers can print to the MFC-465CN. The hard wired Vista machine can print to the HL1440. so I assume that the print server is working properly. The two wireless machines cannot print to the HL1440.

This problem started when I tried to use mac address filtering at my router for added wireless security. My entire networked crashed. I finally called lynksys and they told me that the mac address filtering option had to be disabled. After getting the network to operate again the printing problem developed.

Any suggestions will be appreciated.
