Remember that Linux receives instructions on which applications to open file types with / etc / mailcap . In addition, any type of printable file must be "displayed" or "compiled" by an application that can do this, so thereโs a link to / etc / mailcap . An email application cannot โrenderโ an Excel file, and Photoshop cannot open HTML files :)
According to him, you do not have an entry in / etc / mailcap for the application for processing Excel, Word or HTML files, so the original content is printed, not a "visualized" page (if you print from Linux).
Are you printing from Linux or from Windows ?. If you print from Windows (via the cup server in your Linux box) and it prints normally, then you know that the problem is not with the printer, but with Linux / etc / mailcap .
