Unistall the driver then re-install it.

Just got my ml-2525w printer recently and had a similar issue. It would go offline within an hour or two and the only way to resolve it was to turn the printer off, then back on. Of course, this pretty much defeated the purpose of having a wireless printer..

If you have a wireless router and it's physically located close to your printer, an easy fix is to attach an ethernet cable from your wireless router to your printer. Turn your printer off, then back on and leave the cable connected permanently.

The printer will automatically switch from using it's wireless connection to using it's ethernet connection. The good part is that since you have a wireless router, you can still continue to print to your printer wirelessly.

Also, I have my printer configured to use static IP, partly because I think I noticed the installation program seemed to hardcode the IP address of the printer, even with DHCP. if you still have issues with printing to your printer reliably you may want to try using a static IP address for your printer as well.

By the way, if you use DHCP, in your wireless router, create a DHCP reservation for your printer, so that it always gets assigned the same IP address by your router. This will save you heartache later on.

You might have the Fit to Page option in your Windows printer preferences set to a paper size smaller than what you're printing on.

The ML-2525W could be the perfect "mobile" printer. If it can be powered from a typical
12 volt DC to 120 volt AC converter (Inverter) we can use these in our fleet of service
trucks to provide a true mobile office. The size is perfect and the paper storage provides
an advantage over mobile ink jet printers

Okay, I feel your pain. Uninstall any software you have installed. Hook up the printer with a ethernet cable and turn it on. Go into your router and find the address the router has assigned to it. Be ready to call tech support (seriously). Type the address into you internet browser to connect to the printer. If you are unsure of the next item, please call tech support NOW. Make sure it is set to tcp/ip port setting. Install the drivers only from the cd. Go to printers and find the Samsung. Click on properties and go to ports and confirm that the the printer is set for tcp/ip and click on advanced settings and the address matches the router. Disconect the ethernet cable and see if you can print. If not, call tech support if you haven't already. Please note that I am not a tech. This post is to get you started on the right path and the tech support people are great.

You mean the one right above the power button?

Cancel button: Stops an operation at any time.

Cancel print job: Press (cancel button) during printing. The red LED blinks while the print job is cleared from both the machine and the computer and then the machine returns to ready mode. This may take some time depending on the size of the print job.

Manual print: Press (cancel button) each time you load a sheet of paper in the manual tray when you select Manual Feeder for Source from your software application.

First, plug it into your router or your network via ethernet so it can get an IP address via DHCP. Then browse to its IP address by typing that into a browser window. It's much easier to configure this printer via the web utility built into the printer.

I'm experiencing the same problem. I'm beggining to wonder if the wireless feature works.

havent tried yet but that is what i got from support.

There are a few possibilities; is the status LED solid red? If so, the toner may be exhausted. If not, the next thing I would suggest is deleting the printer in Windows and reinstalling the latest drivers from www.samsung.com...if the problem is an incorrect setting in Windows that will clear it up.

One of two things; either the toner is getting low, or there is a minor error with the unit.

If the toner is getting low this is not a problem; it should still print, but you will need to purchase a new toner fairly soon (the LED will go solid red when the toner is empty).

If it's not toner, then it means one of several minor errors (for example, the front panel isn't shut) is occurring. If you have SmartPanel installed, double clicking on it (the blue S in the system tray) will show you what the error is. If you don't have it installed, go to http://www.samsung.com/us/support/downloads/ML-2525W/XAA to download the latest driver. SmartPanel is included with the driver.

Opened the printer management console SyncThru Web Service via a browser by entering its IP address (as seen in my router's admin webpage).
Clicked Network Settings at the top
Clicked Wireless on the left
Clicked Custom for Wireless Settings
Deleted the SSID that was already there in the field 'Insert New SSID'. Don't search the list.
Clicked Next
Clicked Apply.
The blue light on the printer goes off and you will see on the refreshed page Link Status: Not Connected

To get the current IP of the printer, press and hold the Stop/Cancel button until the status LED goes from a slow blink to a fast blink. That will make it print a config page with the IP address on it. Connect to the SyncThru web interface by putting that address in your browser's address bar. From there you can access the network settings and change to a static IP.

log in to the IP of your printer using http://<ip of the printer> in your browser. Under Network Settings you can change the hostname. (see the SyncThru password answer, you'll need it to complete the step)

Note: Please read all the way through before attempting.

I contacted Samsung support about the availability of an option to disable wireless. They indicated to me that the wireless should disable automatically once a hard lined (LAN)connection was established. I did see wireless after setting mine up, but the next day it disappeared. If all your settings are correct, you may have an issue with the unit. I recommend contacting Samsung support, maybe its a warranty issue. A couple things that you can try is checking the HTTP interface to see if the printer is at least working with just the hard line. You will need a cross over ethernet cable and probably a laptop. Disconnect any devices using the wireless printer and power it off, then back on. If you hold down the triangle button with the circle around it for 5 seconds, and release, the printer will print the network configuration settings. I believe the default is 127.0.0.127. You would assign an IP to your laptop like 127.0.0.128, and the default gateway would be 127.0.0.128. Once you apply the settings, if you open up Internet Explorer and type in http://127.0.0.127(or the IP you got when you printed the network config page.) You should see a page come up for the printer. If not you probably have a problem with the NIC on the printer. At this point you can change the IP settings back to DHCP on the laptop, or whatever you had set up prior.

if you know the IP and can access it at http://<IP> you can change it there (see the SyncThru password answer).
Otherwise you'd need to connect it via USB and run setup again

Re-install the printer driver.
When given the option to connect to the network, don't select DHCP (dynamic IP assignment).
Instead, give your printer a fixed IP address outside the range of DHCP. There's a button to specify an IP address for the printer.
For example, my router assigns DHCP IP addresses in the range 192.168.1.100 thru 192.168.1.250.
I have the printer on 192.168.1.50
The IP assignment screen will ask you for subnet mask IP, and a gateway IP address.
From a Windows PC connected in the same network as the printer:
Go Start/Run... and type "cmd" [ENTER]
Then in the command box, type "ipconfig" [ENTER]. The output will show your subnet mask and gateway.
Once your printer is connected to the network with the set IP address, remove and recreate the printer at each networked PC.
