20 Most Recent D-Link DP-300U (DHDP300U) Print Server Questions & Answers

assuming you mean you are connecting to two separate parallel ports, then your bios settings may have not been set correctly(duplex operation - bidirectional data allowed) or your ports may have been moved by other added hardware, ie your bios may be poor at doing that especially if the parallel ports are on add in card. but since you gave us none of that information, i would try uninstalling both then just add the 1200 first on the first(other) LPT. see what it manages on the one that works on its own. if its ok which it should be then try adding the 1500 after see what happens to both then.

So... you've messed up the IP address on your DP-300U and now you can't even access the web browser configuration page? Yes, it's happened to the best of us. Although I'm sure there are more elegant solutions, one fix is to reset the server to its factory settings and then reconfigure it from scratch. Given that there is no reset button on the DP-300U, resetting can be frustrating, especially if it's asking you for a password that you never created in the first place! Here's what you can do...

1) Install the psadmin software which came with the print server. If you lost the software, you should be able to find it on the web somewhere.
2) Start the software. It should automatically locate your print server.
3) Click on "factory reset". If it demands a password, and you don't know it, try "SYSxxxx" (where xxxx is the last four digits of the MAC address written on the underside of your server)
4) Dust off your Quick Install Guide and go through the unintuitive configuration process. If you no longer have your Quick Install Guide you can find it on D-Link's website.

Good luck!

You can reset the router to factory default settings, press the reset button at the back of the router.

Please note that after RESETTING THE ROUTER to defaults, ALL SETTINGS WILL BE LOST AND YOU HAVE TO RECONFIGURE IT. Generally, after hard reset you get the connectivity, however, you have to make the connection secure etc.
Reset the router to factory default setting, press and hold the reset button for few seconds (It is at the back of the router near the DC Power Jack). The LEDs will then blink and the routers factory settings would be restored. Please note that, after resetting the router you should be able to see the router and connect to it via LAN Cable or Wirelessly as the router automatic assigns the IP Address and gateway etc. Before proceeding to the next step please make sure that you are getting the signals as well as internet. However, the internet connection would not be secure, which can be done later.

Now, all you have to do is connect to the router and secure the connection follow the following steps: -
First you have to access the router through web browser (Internet Explorer) by typing the IP address of your router in the address bar, which is (Default router settings are written under the router)
(unless you've configured otherwise, the default username is admin and the password "leave it blank") and lookup for the options to do the following: -
1. Change the SSID (Name) of the router
2. Change the default administrative user name and password
(The above step would prevent unauthorized access to your router)

Next step is to secure it:
1.On the left-hand side, under Setup, click "Wireless Setup" 2.Under "Wireless Security Mode", select your desired encryption method (preferably WPA2-PSK)
3.Choose a Network Key - it can be anything, as long as it's 8-63 characters in length
4. Click Save Settings.
Now your router and your connection would become secure and the user has to provide the network key to access the internet.

Let me know if any further clarification/ assistance is required.
Hope it helps! Good Luck!

You can try to access the router's page. Try to go to or and then changed the settings from there.
Let me know how it goes.

In order to get your router back to the original settings, you must push in the reset button (usually on the back of the router) for somewhere between 10 and 30 seconds depending on the router. You may need a pin or something small to push in the button, because it can be recessed. Once you have reset the router, the username and password will be changed to the defaults, admin and password, respectively. One thing you must remember is that resetting the router will change all of the router settings back to the factory settings. This means you will lose all of the changes you made since you got the router. Make sure to write down any things you've changed, so you can change them back after the reset. Also, I recommend updating to the latest firmware after the reset.
If you need more help post back! Thumbs and testimonial are welcome!

I had a similar problem to which i thought i had forgotten the password. Apperently the maximum length of the password the print server accepts is 8. It will show you all the chars you type in change password box but will store only the first 8 chars. If you tried a longer password type in the first 8 chars of your password and try. It worked for me and hope it works for you.

Although I was unable to verify this from the dlink support site. Generally on D-link routers if you hold the reset button for 30 seconds it will reload the factory settings. The reset button should be on the back or bottom of the device and you will need a paper clip or something narrow to press it in.

Try using the psadmin software to do a factory reset. If it demands a password to do this, try using "SYSxxxx" (where xxxx stands for the last four digits of the MAC address written on the underside of the server. If you don't have the psadmin software you may be able to download it off the internet. After doing the reset you will need to follow the Quick Install Guide to set up the server. If you lost the Quick Install Guide you can download a new one from D-link's website. The following link may also be helpful: http://www.fixya.com/support/t224263-dp301p_psadmin_password_forgoten
