Hi there.
First of all, I found out in the forums that somebody had the same problem which I will explain but finally he resolved differently. Therefore, I want to post my problem.
I have bought a D-Link DP-G321 wireless print server in order to connect and use OKI-C3300 and HP-5610 printers. My operating system is Windows XP.
I have successfully followed all the instructions and configured the server. However, when I want to print a few seconds after a message "Could not connect printer to LPR port" appears.
I am really desperate.

I tried everything. Please somebody to help.
Second, I am thinking to upgrade to Windows Vista, will it be a problem?
Thanks.
