I have print server DP-301U Pls let me know the default IP address for configuration

This is a wrong problem solver, because 90% of this site contains SPAM instead solution, confusing user totally. Please remove the SPAM from site or remove this site from the Internet. Thank you.

The default IP is 192.168.0.10

Your print server has to have its own IP address. If you have your computer as 198.168.1.1 then your print server would be 198.168.1.2.
You cant have the same IP address on any 2 items on your network.

default IP address of DP-301U is 192.168.0.10

It's in the quick installation guide, which is freely downloadable from their web site. Top of page #3...

"The factory default IP address of the DP-301U is 192.168.0.10."

Download and install <a href="http://www.wireshark.org/download.html">Wireshark</a>.

After installing, click the first button on the toolbar to list available capture devices. Select the interface you use to connect to your network (wired or wireless card) by clicking the "Start" button next to it.

Power off and back on the print server. Watch the log on Wireshark, and look for the D-Link identifier under the "Source" tab. In the same row, it will tell you the IP address the print server has assigned to it. You can then change your computer's IP to be in the same subnet (match the xxx's in the address xxx.xxx.xxx.yyy), allowing you to connect to it.

It should be fine as long as it is in the range that the router can recognize and that it doesn't conflict with another IP address used on another device. Usually on the networks I design I keep the printers on higher IP address so that they can be managed on a certain range.

Is this the wireless print server?

What specifically do you mean by PJL printer block?

1. Set up your print server with an IP address.
2. Ping your printer IP address.
3. If successful, Add printer wizard. Create a new port, Make it TCP/IP port. Put the IP address in the IP address field. Click next and Use Generic 9XXX Raw.
4. Install the driver provided by the manufacturer for your printer and assign it to the Network port.
5. Print.

Hope this helps.
