Well: Maybe CUPS http interface uses "CUPS-Get-Printer" operation, with
'all' for requested-attributes. CUPS-Get-Printer is not yet supported
by php::print::ipp (I think it didn't exists as I wrote CUPS front-end).

What you describe ("mixed response") is "media-supported" attribute 
response to Get-Printer-Attributes operation, which is the standard
IPP response.

Howether, you can try this to collect a complete (but standard) response:
//$requested_attributes = array('job-sheets-supported','media-supported');
$requested_attributes = array('all');
$ipp->setAttribute('requested-attributes',$requested_attributes);
$ipp->getPrinterAttributes();
var_dump($ipp->printer_attributes);

I think it is not in my documentation :(

Currently, there is a lot CUPS specific operations not handled by CUPS
php::print::ipp frontend, and I have no time to implement them, at least
before october.

I will thanks anyone who will take a look to
http://www.cups.org/documentation.php/spec-ipp.html
then implement missings in php::print::ipp (and there is not only CUPS
specific stuff!). There are also some operations already coded but
nether tested because CUPS was not ready...

I recall the cvs:
cvs -z3 -d:pserver:address@hidden:/sources/phpprintipp co phpprintipp

Patches could be sent in this ML.

Try the piece of code I wrote above, but there is no warranty...

Again, it depends on CUPS's response to standard IPP's Get-Printer-Attributes
query.
