    Printer error message “ could not connect printer to port”

    Have a Samsung mono laser printer, which is connected to the network and works fine ( worked fine )

    i have just bought an OKI C511DN colour LED printer, both connected to my network

    I installed through windows using the USB printer lead, then removed this and connected the Ethernet cable ( no wireless ) when I print to the OKI I get the message

    “ could not connect printer to port” if I click on cancel it reappears if I click on OK it prints normally....Imhave tried a few ideas, but nothing seems to stop this message appearing.

    Secondly, Now when I print to the Samsung...I get an error message never seen before, “ the current printer port s not supported etc etc”doesn’t stop the printing, but seeattachment.php Processing...xms to stay on screen......bit confusing..

    can someone please please help..

    It may not be the solution but I saw a similar problem with a setup of 2 computers and 1 printer in our local animal shelter. Turned out a previous employee set the printer up using the USB cable/port then connected everything by Ethernet cable to the Router. To correct the problem only required uninstalling the printer and its software, rebooting the computers then reinstalling with the printer NOT connected until prompted. I chose Network while ignoring the USB and Wireless choices. Then I plugged the printer in via Ethernet cable when prompted, been a year now with no major issues. We can also print from Notebooks via Wi-Fi when installing the software on them and choosing Network.

    I did connect the cable with the printer off as directed.......but when I used the supplied driver disk it couldn’t locate the printer
    Local so I tried the network option, didn’t find on auto but wasn’t sure how to enter the printer up manually, shouldn’t be that difficult....

    will uninstall driver and try again, but repeated this several times already....

    thanks, hopefully some more help will be forthcoming....

    Had similar with Canon mx410, reinstalled the printer driver and communication error messages stopped.

    Yes, it is kind of confusing. Printer was printing correctly, but the status reporting was messed up.

    If working with a networked Samsung monochrome laser printer (I have an ML-2850 myself) I've learned the best way to connect with it is by using its IP address in the Add Printer dialogs. You can use a utility like NirSoft's FastResolver to scan your network to find out which IP address corresponds to your Samsung printer. It usually shows up therein as "SAMSUNGNWP" which translates to "SAMSUNG NetWorked Printer" and you can use the associated IP address as already mentioned (, as shown here, in my case):

    Reading left to right, the scan results show: 1. final octet of IP address, 2. full IP address, 3. Machine name, 4. MAC address.

    Wow that sounds interesting I have the same sumsung printer as you....will try what you suggest and do the same for the OKI printer...
    had problems in the past connecting wireless printers always had to start with the lead, the revert to wireless network....but never a smooth operation.....

    will come back back with the results...

    Hello yes that worked.....didn’t manage to work out the program you suggested, but found the IP from the printer properties web tab

    The oki is fine, but don’t think the Samsung driver install offers a network option.....also can’t find the Samsung network address

    You can use the FastResolver utility to obtain MAC addresses for all active devices on your network. As long as your Samsung printer is turned on and attached to the Ethernet, FastResolver should see and report its MAC address and IP address at a bare minimum. By disconnecting all devices from the network except your router, one PC and the printer, you can work out which MAC address goes with each device by process of elimination (many routers have the MAC address inscribed on a label somewhere, and the IPconfig command will tell you the PC's MAC address, labeled "Physical address" in the ipconfig /all output).
