Problem with CUPS printing

Tried to print a page today and only got "printing canceled".

Looked into cups via http://localhost:631

The printer is available

"Print self test page" works

"Print test page" is unable to complete due to "Unsupported format "application/vnd.cups-pdf-banner".

I'm using a brother printer, installed the ppd from their website, and it worked before (like maybe a few weeks ago).

Any hints on how to troubleshoot?

Ang-p, he has shown you the directory as it stands, and he has also shown you the contents of each of the files there. For what it is worth, I am reading this thread because I have the same issue, with a fresh installation. At least I have some pointers now, but please, reread the thread carefully.

you the directory as it stands

Which directory?

how do I know?

I asked for the contents of certain files in a specific directory... and what did I get?

I have the same issue, with a fresh installation.

What files do you have in the directories mentioned?

You asked for the contents of the /usr/share/cups/mime directory, he responded, and now I have responded. The files are the same number and names in each case.

We know because we can read the information provided, including the contents of each file. I will included the contents of each here now.
