You sent a document to your Brother HL-L2350DW, the LCD looks fine, but Windows or your Mac stubbornly insists the printer is "Offline" and nothing comes out. It is one of the most frustrating quirks of this monochrome laser machine, because the printer itself is usually working perfectly; the offline label almost always points to a stalled queue, a Windows toggle, or a Wi-Fi drop rather than a hardware fault.
The good news is that you can clear it yourself in a few minutes, and you rarely need anything more drastic than flipping a setting or power-cycling your network.
Work through the fixes below in order. The first steps are the safest and resolve the offline state in most cases, while the resets at the end are reserved for when nothing else brings the printer back.
Because the HL-L2350DW connects over USB or 2.4 GHz Wi-Fi and has no Ethernet port, you can skip any advice about checking a network cable; there simply is not one on this model.
Start With the Printer Itself Before Blaming the Computer
Before changing any settings, confirm the machine is awake and free of errors. Make sure the HL-L2350DW is powered on, then wake it from Sleep Mode by pressing any button on the control panel.
Now read the LCD carefully. Messages such as a paper jam or toner empty will stop printing entirely and can make the computer report the printer as offline. Clear any error shown before you continue.
Finally, confirm the connection you are actually using. If you print over USB, make sure the cable is plugged directly into the computer and not through a hub. If you print wirelessly, confirm the printer is connected to your network. There is no Ethernet port on this model, so there is no network cable to inspect.
Untick "Use Printer Offline" and "Pause Printing" in Windows
Windows has a manual offline switch that gets toggled by accident or set automatically after a connection hiccup, and it stays on until you clear it. This is the single most common cause of a phantom offline state, so check it first.
On Windows 10 or earlier, right-click the Brother machine icon and choose 'See what's printing'. Open the 'Printer' menu and remove the checkmark from 'Use Printer Offline'. While you are in that menu, also clear 'Pause Printing' if it is checked.
On Windows 11, reach the same queue through Start > Settings > 'Bluetooth & devices' > 'Printers & scanners', select the machine, then choose 'Open print queue'. From there you can confirm the printer is not paused and send your job again.
Make the HL-L2350DW Your Default Printer
If your computer is quietly routing jobs to a different printer (or to a duplicate copy of the Brother that Windows created), your real machine can look offline while jobs vanish. Setting it as the default fixes this.
In Windows 8 or 10, open Control Panel > 'Hardware and Sound' > 'Devices and Printers', right-click the Brother machine and choose 'Set as default printer'. On a Mac, there is no offline checkbox to worry about; instead make sure the Brother machine is the one selected to print inside the application you are using before you hit print.
Clear Out Stuck Jobs Jamming the Queue
A single corrupted or stalled document can freeze the entire print queue, and Windows often flags the printer as offline while that job sits there. Emptying the queue gives the printer a clean start.
On Windows 11, choose 'Open print queue', open the menu, and select 'Cancel all'. On Windows 10 or earlier, open 'See what's printing', then use the 'Printer' menu to cancel the queued documents.
On macOS 13 or later, go to Apple Menu > 'System Settings' > 'Printers & Scanners', select the machine, choose 'Print Queue', and delete the jobs. On macOS 12 or earlier, go to Apple Menu > 'System Preferences' > 'Printers & Scanners' and choose 'Open print queue' to remove the stuck jobs.
Power-Cycle Your Network in the Right Order
For wireless drop-outs, a clean restart of everything on your network usually re-establishes the link between the printer and your computer. The order matters, because each device needs the one before it to be ready first.
Position the HL-L2350DW physically closer to the router to give it a stronger signal. Turn off the router, the computer, and the Brother machine. Turn the router back on first and let it fully start up.
Turn the computer back on next. Turn the Brother machine on last, and wait a few minutes for everything to reconnect. Once the machine is back on, send a test page to confirm the wireless link has come back.
Confirm Your Router Is Broadcasting a Named 2.4 GHz Network
This is the fix that catches owners with modern dual-band or mesh routers off guard. The HL-L2350DW connects only to the 2.4 GHz band and will not see or connect to a 5 GHz band, so if your 2.4 GHz network is hidden, disabled, or merged with 5 GHz, the printer keeps falling offline.
On a dual-band or mesh router, give the 2.4 GHz network its own unique name. Using the same network name (SSID) for both 2.4 GHz and 5 GHz can cause repeated connection loss, so split them and connect the printer specifically to the 2.4 GHz network.
If your mesh setup refuses to hold the printer on Wi-Fi no matter what, switching to a direct USB connection is a legitimate fallback that takes the wireless variable out of the picture entirely.
Rejoin Wi-Fi With the WPS One-Push Method
If the printer simply lost its place on the network, the WPS one-push method reconnects it without typing a password. Have your router within reach so you can press its WPS button at the right moment.
- 1.On the printer, press the up/down arrows to select [Network] and press OK.
- 2.Select [WLAN(Wi-Fi)] and press OK.
- 3.Select [WPS] and press OK.
- 4.When [WLAN Enable?] appears, press the down arrow to select On.
- 5.When the LCD shows [Press Key on rtr], press the WPS button on your router and then press the button on the printer.
The LCD shows [Connected] when wireless setup succeeds. If it does not connect, move the printer closer to the router and run through the sequence again.
Update the Driver and Firmware
An outdated or damaged driver can make a perfectly healthy printer appear offline, and a firmware update sometimes resolves lingering connection bugs. Refreshing both is a clean way to rule out software gremlins.
Download and reinstall the latest full driver and software package for your operating system from the official Brother support site, then update the printer's firmware. Removing the existing driver first and installing the current version fresh clears out any corrupted files that may be causing the offline state.
If you prefer to work from your phone, you can update the firmware using the Brother iPrint&Scan app on Android or iOS, which is the official companion app for this model.
Reset the Network Settings to Factory Defaults
When the printer still will not come back online after the steps above, resetting its network configuration clears any corrupted wireless settings. Be aware this is a data-affecting step. It restores all wired and wireless network settings, including the password and IP address, to factory defaults, so you will need to reconnect Wi-Fi and reinstall the driver afterward.
Press the up/down arrow buttons to select [Network] and press OK. Select [Network Reset] and press OK. Press the down arrow to select [Yes].
The machine restarts. Once it is back up, reconnect to your 2.4 GHz network (for example using the WPS one-push method above) and reinstall the latest driver so the computer recognizes it again.
Try the Reset Menu or Reach Brother Support as a Last Step
If a network reset alone does not resolve things, the broader Reset menu gives you additional reset options. As with any reset, expect to set the printer up again afterward, so treat it as a last resort once the simpler fixes have failed.
Select [Initial Setup] and press OK. Select [Reset] and press OK. Choose the reset type and press OK.
Confirm by selecting [Yes]. The machine restarts. If the offline problem still persists after that, turn to the official Downloads and FAQ pages for the HL-L2350DW and contact Brother support so they can help you diagnose the connection directly.
Frequently Asked Questions
Why does my HL-L2350DW keep going offline on a mesh or dual-band router?
The HL-L2350DW connects only to the 2.4 GHz band and will not see or connect to a 5 GHz band. If your router uses the same network name for both 2.4 GHz and 5 GHz, that can cause repeated connection loss, so give the 2.4 GHz network its own unique name and connect the printer to it. If a mesh setup still will not hold the connection, a direct USB connection is a reliable fallback.
Does the HL-L2350DW have an Ethernet port I should check?
No. This model has no wired Ethernet port; it connects over USB or 2.4 GHz Wi-Fi and supports Wi-Fi Direct. Any advice to check an Ethernet cable applies to other variants, not the HL-L2350DW, so there is no network cable to inspect on this machine.
Will resetting the network erase my Wi-Fi settings?
Yes. A network reset restores all wired and wireless network settings, including the password and IP address, to factory defaults, and the machine restarts. After the reset you will need to reconnect the printer to Wi-Fi (for example via the WPS one-push method) and reinstall the driver.
How do I update the printer's firmware?
You can update the firmware from a computer by downloading the latest software for the HL-L2350DW from the official Brother support site. Alternatively, you can update the firmware directly from your phone using the Brother iPrint&Scan app on Android or iOS.
The "Use Printer Offline" box keeps coming back. What is happening?
Windows can re-enable the offline toggle after a connection interruption, which is why clearing it on Windows 10 or earlier (right-click the Brother icon > 'See what's printing' > 'Printer' menu, then untick 'Use Printer Offline') often needs to be paired with fixing the underlying connection. Power-cycle your network in order and confirm the printer is firmly on your 2.4 GHz network so the offline state does not return.
