Unsupported format 'application/vnd.cups-banner'!

[Silas Silva]

Hi all.

I just installed cups 1.4.6 from pkgsrc (www.pkgsrc.org) in my NetBSD 5.1 system.

Printers are found and installed fine, but when I try to print a test from the web interface, this error shows up:

Unsupported format 'application/vnd.cups-banner'!

After enabling debugging in cupsd.conf, I could get the following information:

(...)

D [19/May/2011:16:29:38 -0300] PID 12564 (/usr/pkg/libexec/cups/cgi-bin/printers.cgi) exited with no errors.

Both mime.types and mime.convs have an entry for application/vnd.cups-banner:

$ grep banner *
mime.convs:application/vnd.cups-banner  application/postscript          33      bannertops
mime.types:application/vnd.cups-banner  string(0,'#CUPS-BANNER')

And bannertops exist.

What could be happening? Is there any more I can do to get more information?

Thanks in advance.
