[IPP] pwg-5100.13 section 5.6.39 printer-supply encoding

["Rizzo, Christopher via ipp" <[e-mail]>]

Table 9 has optional printer-supply (1setOf octetString(MAX)) keywords.

Some supplies have colorants, others have colorantIndex = 0 ("this supply does not depend on a single specified colorant").

Must each entry in the set of octetStrings contain the same SNMP Supply Objects (matching cardinality), or can colorant objects be present in an octetString for those supplies that have a colorant, but not present in an octetString for those supplies that do not have a colorant?

For example, must we do this:


// Black toner.

printer-supply[1] =

type=toner;maxcapacity=100;level=75;index=1;markerindex=1;

class=supplyThatIsConsumed;unit=percent;

colorantindex=1;colorantrole=process;colorantname=black;

coloranttonality=256;



// Fuser does not have concept of colorant.

printer-supply[2] =

type=fuser;maxcapacity=100;level=96;index=2;markerindex=1;

class=supplyThatIsConsumed;unit=percent;

colorantindex=0;colorantrole=???;colorantname=???;

coloranttonality=???;

Or should we do this (is it legal to have colorant entries for some supplies, but not have colorant entries for others in the set (non-matching cardinality)?):


// Black toner.

printer-supply[1] =

type=toner;maxcapacity=100;level=75;index=1;markerindex=1;

class=supplyThatIsConsumed;unit=percent;

colorantindex=1;colorantrole=process;colorantname=black;

coloranttonality=256;



// Fuser does not have concept of colorant.

printer-supply[2] =

type=fuser;maxcapacity=100;level=96;index=2;markerindex=1;

class=supplyThatIsConsumed;unit=percent;colorantname=unknown;



And since colorantname is REQUIRED, what value should it have for a supply that is not associated with any colorant (unknown or other appear to be the only available values in RFC3805)?

Thanks,
Chris
