The catch
Brother PT-E310BT
You still have to cut by hand between labels.
Side by side
PT-E310BT is the pick if you edit jobs on a phone. PT-E510 is the better fit when 24 mm media and automatic half cuts count for more than Bluetooth. The higher model number shifts the workflow in both directions, with gains and losses.
Before you buy
A technician gets a phone route with E310BT, though cutting is manual. E510 brings automatic half cuts and wider tape but lacks the same Bluetooth workflow. When names change on site, E310BT may be more convenient. When prepared sequences have to stay in order, E510 can fit better.
Where this comes from
Match where you edit with how you finish the job. Neither feature is inferred from the model hierarchy.
The catch

Which one fits
Bluetooth and Pro Label Tool support come with the E310BT.
That range is handled by the narrower printer.
The documented half-cut option comes with the E510.
The E510 takes the wider media.
In practice
A technician gets a phone route with E310BT, though cutting is manual. E510 brings automatic half cuts and wider tape but lacks the same Bluetooth workflow. When names change on site, E310BT may be more convenient. When prepared sequences have to stay in order, E510 can fit better.
Match where you edit with how you finish the job. Neither feature is inferred from the model hierarchy.
With compatible backing, E510 can cut through the label face and leave the backing joined. Neighboring identifiers then stay together until you place them. E310BT works through a manual Cut-Pause workflow instead. What you gain is easier organizing and handling of the batch. It is not a verified number of seconds saved, and it does not mean every medium can be half-cut.
Documented automatic half cutting is set against a manual cutter. Confirm the compatible media and cutter settings.
CSV is required for the printer database, and E310BT mobile database use needs it as well. A Windows desktop application may accept XLSX, but that does not mean the raw workbook will transfer to the printer or phone unchanged. Export the fields you intend to use, then check a sample label before you count on the job away from the desk.
Notes on the official model page about databases separate Windows editor formats from CSV requirements for the printer and mobile.
