DPR 1260 will not work at all

no it is not..

download latest drivers and install with printer unplugged...it will install software to c:\program files\samsung\ and then 2 more folders in you will get the drivers folder - add printer and just do have disk and browse to that folder.

Chapter 3 - Configuration
This section will show you how to configure your new D-Link wireless print server using the web-based configuration
utility.
Web-based Configuration Utility
The IP address of your print server will be automatically assigned by your router.
To access the print server’s web-based configuration interface:
Windows® XP users:
Double-click on the My Network Places icon on your desktop. Your print server will be displayed as “DPR-1260:
dlinkps-xxxxxx” (where xxxxxx is the last 6 characters of your print server’s MAC address). If you do not see the print
server or have UPnP enabled, please refer to page 13.
Windows® 2000 users:
You will need to write down the MAC address located on the bottom of the print server (E.G. 00-54-23-45-f5-b6). Open
a web browser and enter the following:
http://dlinkps-XXXXXX
XXXXXX = the last six characters of your MAC address.
Note: Some printer software features may not work
while connected to the print server such as ink level display.

This will prove the print server is working. If you can not access the web interface then it may not be getting an address from the router

did you install the software that comes with the print server? if so, did you configure the software to recognize the printer?

Try to log in with "admin" as the P/W (without the quotes.

this kind of problem occurs in dlink router sometimes & after some time router stop responding after 10 -15 min & once u reboot the router it again start work for a while. the best solution to this problem is to reset the router back to its factory defualt settings u can do this by press the reset button on the back on the router ( it looks like a small hole u have to use a pin for press that button) once u have reset the router to factory default settings just reconfig the router & i am sure it will start working fine in case u still face the same problem just contact D-link or send me the details about the problem & the physical setup of ur router & printer etc

Try to upgrade the firmware revision to the last one (1.21).
I had similar problem with the dpr-1260 firmware rev 1.00.
Now after the firmware upgrade the problem seems solved

The DPR-1260 is pretty easy to configure and works well with my HP Laser 1012, HP Photosmart 8250, and HP OfficeJet 5610. The Operating System on the computer is what matters... as long as it's running Windows XP, Vista, or a server edition like Win2003, you should be fine. I can't speak to the Mac environment, as I don't have any experience there. As for the Dymo Duo, I can't tell you how well it'll work in this environment, but based on my experience with it and many other print servers that I've tried, I can't think of a better configuration to try. Personally, I would recommend the DPR-1260 to anyone... just make sure you follow the installation instructions in the users manual carefully, and you can't go wrong. I love mine, hopefully you'll enjoy yours as well.

To get into the web configuration you need to know your firmware on the DPR-1260. If it is 1.12, us http://dlinkps-xxxxxx where the X's are the last 6 number of the mac address. If it is 1.20 and up, use http://dlink-xxxxxx, where the x's are the last 6 number of the mac address. If you do set it up as DHCP or static and know the ip address of the print server just type in the ip address of the print server on the address bar.

Make sure your printer is on the compatibility list provided by D-Link. The list is in the following link: http://support.dlink.com/faq/view.asp?prod_id=2316&question=DPR-1260
