Our non-Link-OS printers like the 105SL+ use the same published MIB as our printserver. You can find that document here Support for the ZebraNet 10/100 Print Server. Our current SNMP MIB for our Link-OS printers will be available online soon. The last zebra.com website update broke the link. I'll reply back when it gets posted. To know if your printer is Link-OS or not, check out the product page on Zebra.com. The printserver MIB should be compatible across most of out products, but Link-OS adds several hundred more oid's.
