DEVICE STATUS OFFLINE

First check on the device and printer under control panel if the status of your printer is offline or ready. If it is offline check your usb cable if properly connected and if ready state then if you send print job set to offline try to reinstall the driver. hopefully it will help you.

If your computer is USB connected make sure that the cable is connected and that the printer is powered up. If you are connected to the printer over your network through wifi or ethernet, make sure that each device (computer and printer) is connected.
If all of these are in order and the printer still shows offline, try re-installing the software that came with the printer. Sometimes the software needs to be re-installed due to corrupted files.

Depends on your OS you need find "printer and faxes" or "printer options on the hardware.

• 
  Open the Start menu and click on the "Devices and Printers" icon. This will open a window with a list of the printers currently set up on your computer.
  
  
• 
  Double-click on the icon of the printer you want to change to online. The status of the printer will be shown as either "Printer: Ready" or "Printer: Offline."
  
  
• 
  Click on "Printer: Offline" and the Printer menu will appear. Click on "Printer" in the menu bar and uncheck "Use Printer Offline." This action will change the printer from offline to online.
  
  

Go to devices and printers to see if your printer is set to default. Make sure the printer cables are plugged in tight. Offline means it is not getting a signal . In Case You Still Having Problem Then Follow Us For On : Brother Printer Support

If it used to work, then try unplugging and reconnecting the AC power cable for USB scanners. No guarantees at all, but it may work. Unplugging and reconnecting the Firewire cable in XP also sometimes works. Give it a few seconds to be detected.

The printer offline error mostly troubles windows 7/8/10 users, The printers loses connectivity even when it is connected and operating. The status message displays offline on the computer, and the printer does not print. An Offline status indicates that the computer has failed to communicate with the printer. In some network conditions, the printer might get offline unexpectedly.

Before going to the solution for this you must know when and why printer offline error takes place:
The error may appear when Windows 8 diagnoses that the printer is unavailable, but unfortunately, most times it fails to tell whether the printer is really offline or if it has connectivity problems or printing errors. Reasons why your printer appears to be offline, include problems with hardware, such as disconnected cables or malfunctioning equipment, and problems with software, such as corrupted or incompatible driver files.
These might occur when:
1. The connection between the computer and the printer is slow/unresponsive.
2. The printer has encountered an internal error
3. There are multiple unfinished print jobs in the queue.
There are some simple steps you can follow before going to any complicated way:
Your printer offline can be a problem with the driver software. This is a small piece of code that Windows and the printers use to "talk" to each other. If the driver software is outdated, corrupted or incompatible with the version of Windows that you have installed, you may need to update it.
Restart the printer and the computer or unplug its USB cable.
Do check that the printer's power cable is plugged into an electrical outlet. If the printer is connected to a power strip, make sure the strip itself is connected to the electricity supply and is turned on.
In case you are using a network printer both wired or wireless, You restart the router as it may cause due to network failure.
Different manufacturers come with their own diagnostics software which can inform the user about the problems coming up (Ex : HP's Print and Scan Doctor), Use it as it will be really useful.

have you tried doing a local connect using a crossover cable to the printer to see if it is the printer or the 2k3 server?
I have seen this issue when terminal services are enabled on the server.
if when you connect locally to the device using x-over it still does it it may need to have the nib firmware updated, however if it doesnt I would run a packet sniffer on the network jack that the device is plugged into and check to make sure that the port is good and transmitting and receiving all packets check the network cable and replace that and if all else fails try the device on a different network port.

It sounds like the print driver is not playing nice. Try removing the printer and uninstalling the driver from the DRIVERS TAB found in the PRINT SERVER PROPERTIES menu. Then reinstall the printer using OLDEST drivers (version 1.0) usually on cd that came with the unit.
