[Printing-architecture] Get all the job attributes

Hi

I want to get all the job attributes like Pagesize, PaperType, Paper source
for the job. I am using the following code to get that information.

static const char * const jattrs[] =  /* Job attributes we want */
  {
    "job-template",
    "job-description",
    "all"
  };
    httpAssembleURIf(HTTP_URI_CODING_ALL, uri, sizeof(uri), "ipp", NULL,
         "localhost", ippPort(), "/printers/%s", printer);
  /* Getting the resource */
  resource = uri + (strlen(uri) - strlen(printer) - 10);
  http = http_connect_local();
  request = ippNewRequest(IPP_OP_GET_JOB_ATTRIBUTES);
  ippAddString(request, IPP_TAG_OPERATION, IPP_TAG_URI, "printer-uri",
NULL,uri);
  ippAddInteger(request, IPP_TAG_OPERATION, IPP_TAG_INTEGER,
"job-id",job_id);
  ippAddString(request, IPP_TAG_OPERATION, IPP_TAG_NAME,
"requesting-user-name", NULL, cupsUser());
  ippAddStrings(request, IPP_TAG_OPERATION, IPP_TAG_KEYWORD,
"requested-attributes",
    (int)(sizeof(jattrs) / sizeof(jattrs[0])), NULL, jattrs);

  response = cupsDoRequest(http, request,resource);
  attr = ippFirstAttribute(response);


The output of the code is :
attributes-charset,utf-8
attributes-natural-language,en-in

1. The media-col attribute is not returned in the request. How I can change
the request to get media-col ?
2. The paper type is given as "MediaType Envelope", How I can get the
media-type from the response ? I tried:
           if ((attr = ippFindAttribute(response, "MediaType",
        IPP_TAG_KEYWORD)) != NULL && ippGetCount(attr)>0){


             if ((attr = ippFindAttribute(response, "media-type",
        IPP_TAG_KEYWORD)) != NULL && ippGetCount(attr)>0){

It will only be returned if it was sent in the original print request.  Currently we do not synthesize IPP attributes when the Job is created, just when it gets sent to an IPP printer.

If you'd like us to do so, please file a bug at:

Thanks!

MediaType (like all PPD options sent as attributes) will have the IPP_TAG_NAME syntax.

while "media-type" (the IPP attribute) can be IPP_TAG_NAME or IPP_TAG_KEYWORD, so here I'd usually look for IPP_TAG_ZERO and check for a NULL string value (which would indicate something that is not a name or keyword).

Sir Thanks for the reply. My problem is solved. But, I also want to see
