ZPL on Printronix printers

Short answer: Printronix documents a ZPL emulation mode on 2 model(s) in our database, published under the name ZGL is Printronix's Zebra ZPL interpreter; the manual's own title is 'ZGL, a Zebra ZPL Printer Protocol Interpreter'. Not on by default (Active IGP Emul is set to ZGL), a compatibility mode is selected (ZPL-I / ZPL-II, factory ZPL-II) and coverage is not one-to-one: the manual lists behaviour differences and per-command 'Ignore' settings. That name is what you will find in the manual and what support will ask you about — not "ZPL support".
This is emulation, not native support. Printronix decides how much of ZPL its mode covers, and Labelixa has not physically tested it. What that means in practice

These are Industrial units from the T6000e family, printing at 203/300/600 dpi with a 104/166.4 mm print width, reachable over Ethernet, RS232, USB. 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.

Printronix ships these at 203/300/600 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 Printronix claims here rest on the vendor's programming 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.

Or use a printer that runs it natively

ZPL is documented as a native language on printers from Zebra. If the hardware is still your choice, that removes the emulation question entirely.

Questions

Will my existing ZPL labels print unchanged on a Printronix printer?
Not necessarily. Printronix's mode covers the subset of ZPL that Printronix 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.
