I understand different printers supports different print format.<br>
<br>
May I suggest to change the wording in the "print self-test page" from "You are using the wrong driver" to "Printer Self-Test Page"?<br>
The string I believe is located in commandtops filter.<br>

<br>
Well, the content can't be made that neutral because printers don't support a standard set of file formats (yet).<br>
<br>
However, CUPS 1.4 and later *do* use a new (simple) CUPS banner format for the test page instead, using a filter to generate the necessary content for the printer. It sounds like either Ubuntu's CUPS is broken or the correct driver was not chosen for the printer.<br>
