These are Industrial, Desktop units from the CLNX, CT4-LX, WS4 family, printing at 203/300/305/609 dpi with a 104/168 mm print width, reachable over Bluetooth, Ethernet, Parallel, 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.
SATO ships these at 203/300/305/609 dpi, so the same ZPL 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 SATO claims here rest on the vendor's product page (specification table), the vendor's spec sheet, a vendor support article. Source type is part of the evidence: a manual ships and is versioned with the product, while a support article can change without notice.
SATO does not stop at one: the same records document emulation for 5 printer languages in total. The others are DPL, EPL, IPL, TSPL.
ZPL 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 ZPL labels print unchanged on a SATO printer?
Not necessarily. SATO's mode covers the subset of ZPL that SATO 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.
