These are Industrial, Desktop units from the TD-4T, TJ family, printing at 203/300 dpi with a 105/107/108 mm print width, reachable over Bluetooth, Ethernet, RS232, USB, USB Host, WiFi. The interface is part of the answer: an emulation mode is selected on the device or by a prefix in the stream, so how you reach the printer decides how you switch it.
Brother ships these at 203/300 dpi, so the same EPL coordinates land at different physical sizes depending on which unit you got — check that before you blame the emulation for a layout that came out wrong.
The Brother claims here rest on the vendor's user manual. Source type is part of the evidence: a manual ships and is versioned with the product, while a support article can change without notice.
Brother does not stop at one: the same records document emulation for 3 printer languages in total. The others are DPL, ZPL.
EPL is documented as a native language on printers from Zebra. If the hardware is still your choice, that removes the emulation question entirely.
Will my existing EPL labels print unchanged on a Brother printer?
Not necessarily. Brother's mode covers the subset of EPL that Brother chose, so fonts, barcode types and graphics are the usual places where output differs. Send one real label to the device and compare before you migrate a fleet.
