I recently moved my printer from a Windows 7 computer, a Brother MFC-8640D, and connected Via USB to an Asus RTN66U router. It's setup a LPD/LPR resource. When using Mint Perta and trying to print from Firefox, the page that is produced from a print job send to the networked printer consistanly prints in large font: "ERROR NAME; COMMAND; pop OPERAND STACK;".
If I instead print the document to create a local PDF file in Firefox and then open the PDF using the default PDF reader, the PDF reader prints the document correctly most of the time. Occasionally I'll get the same error as I get printing through Firefox.
Any ideas of what to do to correct the printer error? I assume it must be some sort of configuration error. No special printer configuration was done by me and the printer configuration was done using Mint's standard printer configuration. The Mint computer is connected to the Asus router using a standard network cable.
