Second you have to install the WPCONFIG application onto the machine, this is found on the disks that were shipped with the product. Once this has been done you can run the WPCONFIG and you select the print server to which you wish to configure in the main menu. You then configure the logical printers; the menu below shows the available logical printers for an IOPRINT+ Jr.

In logical printer 1, I have asked the printer to stream '0A0C21' prior to the print being sent to the printer. Any Hexadecimal characters can be entered into this string. You then Save to Device and confirm the changes to the device by clicking on OK. This is now set active.
