To provide a proper answer, we’d need to know what kind of Zebra printer it is, how it is connected to your network, how the spooled file is structured and possibly a number of other items. We don’t know yet if the specific printer is even capable of being controlled by anything but Windows.
You know the printer, the network and how the spooled file was created, which includes possible printer control data embedded in the data stream.
IBM supplies basic information for all types of printers that are known to be used for AS/400s. You should begin by a review of <a href=”https://www-304.ibm.com/support/docview.wss?uid=nas1ccf052269288d640862569c1006cd157″>Information on Printers from Zebra/Eltron</a>. You will probably have more specific questions after that.
