What to do if Brother Printer shows a data transmission error?
- AAshley HillSep 4, 2025
If a data transmission error appears on your personal computer when using the Brother QL printer, verify that the correct port is selected in the Printer Properties dialog box under the “Print to the following port” list. Also, check if the printer is in cooling mode (orange flashing LED). If so, wait until the LED stops flashing before trying to print again. Finally, if other users are printing large amounts of data via network, try again after their jobs are completed.
