DYMO Label Printer Says Disconnected

Do this first

1. Turn off the DYMO. Unplug both cords from the printer itself, the power cord and the USB cable.
2. Unplug the other end of that USB cable from the computer.
3. Restart the computer and let it finish starting up all the way.
4. Plug the power cord back into the DYMO and wait for it to power on.
5. Plug the USB cable back in, computer end last.
6. Open your label software. The printer should show as connected.

Why this works. The computer keeps a record of the printer from the last time it was plugged in. When that record goes stale, the software keeps looking for a printer that is not there anymore. Unplugging everything and restarting clears the record, so the computer finds the printer fresh.

If that did not do it

Try these in order. Most people never need to go past the first one.

Restart the DYMO background service

The label software does not talk to the printer directly. It goes through a helper that runs quietly in the background, and if that helper has stopped, the printer looks disconnected even though nothing is wrong with it.

1. Press the Windows key and type Services.
2. Open Services from the results.
3. Scroll to the entries that start with DYMO.
4. Right-click each one and choose Restart.
5. Open your label software again.

If Windows asks for an administrator password. On most of the computers
we look after, everyday accounts do not have administrator rights. That is
deliberate, and it is one of the things that keeps the place safe. It also
means this particular step needs us. Text or call us and we will do it in a
moment, or carry on to the next thing below and see if that sorts it.

Try a different USB port

Plug the DYMO straight into the computer rather than into a hub, a dock, or a monitor. These printers pull power over the USB cable, and a hub does not always pass along enough of it.

If the computer has ports on both the front and the back, the back ones are usually connected more directly.

Check that Windows has not marked it offline

Windows will sometimes flag a printer as offline and then keep it that way even after the printer comes back.

1. Open Settings, then Bluetooth & devices, then Printers & scanners.
2. Click your DYMO in the list, then click Open print queue.
3. Open the Printer menu at the top of that window.
4. If Use Printer Offline has a checkmark next to it, click it to clear the checkmark.

Swap the USB cable

If you have another USB cable of the same type, try it. Cables that live on a desk and get moved around do eventually fail, and a failing one often looks exactly like this.
