Hi Michael

The following is description for "printer-uri-supported" in RFC2911.

4.4.1 printer-uri-supported (1setOf uri)
This REQUIRED Printer attribute contains at least one URI for the
Printer object. It OPTIONALLY contains more than one URI for the
Printer object.
An administrator determines a Printer object's
URI(s) and configures this attribute to contain those URIs by some
means outside the scope of this IPP/1.1 document. The precise format
of this URI is implementation dependent and depends on the protocol.
See the next two sections for a description of the "uri-security-
supported" and "uri-authentication-supported" attributes, both of
which are the REQUIRED companion attributes to this "printer-uri-
supported" attribute. See section 2.4 on Printer object identity and
section 8.2 on security and URIs for more information.

I return the following values for the attribute.

IPP:     ATTRIBUTE: printer-uri-supported
IPP:       VALUE: Syntax=URI, Data=ipp://DEV334142.local/ipp/print
IPP:       VALUE: Syntax=URI, Data=ipp://DEV334142.local/ipp/faxout

But APVT 1.4 complain:

_Check printer-uri-supported._FAIL

"/ipp/faxout" MUST NOT be listed in printer-uri-supported for printer 
but found URI(s) of which path portion(s) are "/ipp/faxout".

Found 2 different resource partitions in printer-uri-supported. 
printer-uri-supported MUST NOT list special URIs. (

"/ipp/print",

"/ipp/faxout"

)


{

Name = "Check printer-uri-supported.";

Operation = "Get-Printer-Attributes";

RequestAttributes = (

{

"attributes-charset" = "utf-8";

"attributes-natural-language" = en;

"printer-uri" = "ipp://DEV334142.local.:631/ipp/print";

"requested-attributes" = "printer-uri-supported";

}

);

RequestId = 66447;

ResponseAttributes = (

{

"attributes-charset" = "utf-8";

"attributes-natural-language" = en;

},

{

"printer-uri-supported" = (

"ipp://DEV334142.local/ipp/print",

"ipp://DEV334142.local/ipp/faxout"

);

}

);

StatusCode = "successful-ok";

Successful = 1;

Version = "2.0";

}


It seems I should only return "ipp://DEV334142.local/ipp/print " for 
"printer-uri-supported" for printer, and return 
"ipp://DEV334142.local/ipp/faxout" for
"printer-uri-supported" for faxout ?

Which rule in IPP specification does the APVT 1.4 obey ?

Regards

Walter
