We have purchased several Zebra QL420 PLUS (wireless) hip printers to print barcode labels from an application that runs on our Redhat 5.2 server. We've tried setting up the printer using the Zebra driver that comes with Cups v1.2 and as a "raw" printer. As a raw printer the all we get is a form feed when we attempt to print to it. No text at all. As a "Zebra" printer we get control codes with the embedded text. I guess I need any pointers on how to fix this. Is there a way to create a ZPLII file that can be piped directly to the printer? I'd like to isolate that the application is or is not the problem.
