The He/O2 printer cable connects your label printer's RS-232 interface to the auxiliary attachment connector on

the He/O2 analyzer. If your Zebra printer doesn't have an RS-232 interface, don't worry—Zebra printers are

modular, and you can install an RS-232 interface yourself without any tools.

For ZD421 models, you'll need module P1112640-016

For older models, search for "Zebra serial module."

Do you want to know when the cable is available? Please set up a notification using the "Watch availability" button. And if you're technically inclined, the cable design is straightforward enough to

DIY—schematics are available on our website.
