Subject: [printing-spool] PAPI v1.0 final functionality
I am proposing that we add content to cover the following areas prior to
finalizing v1.0 of the spec.
Creation of a Document object
Administrative operations
Add/Remove destination (printer/queue)
(modify is already in the spec. but may need a
more complete description.)
Enable/Disable destination (printer/queue)
Enable/Disable job creation on a
particular destination.
Promote Job
make a job the next one to process.
If there is anything else that others would like to add, please bring
it up now. I would like to finalize the content of PAPI v1.0 in the
next few weeks so that there is some small chance that it can be
completed this fall.
-Norm
More detail on document object interfaces will follow next week (I
hope), but I propose that the additions for new administrative
operations be as follows.
papi_status_t papiPrinterAdd(papi_service_t handle, char *printer_name,
papi_attribute_t **attributes, papi_printer_t *printer);
INPUTS
handle - Handle to the print service on which to create the
printer object.
name - Name or URI of the printer to be created
attrs - Attributes to associate with the printer object
being created.
OUTPUTS
printer - The printer object created on the print service.
RETURNS
If successful, a value of PAPI_OK is returned. Otherwise an
appropriate failure value is returned.
EXAMPLE
papi_status_t status;
papi_service_t svc = NULL;
papi_attribute_t **attrs = NULL;
papi_printer_t printer = NULL;
...
papiAttributeListAddString(&attrs, PAPI_EXCL,
"device-uri", "socket://printer:9100");
papiAttributeListAddString(&attrs, PAPI_ATTR_APPEND,
"document-format-supported", "application/ps");
papiAttributeListAddString(&attrs, PAPI_ATTR_APPEND,
"document-format-supported", "text/plain");
papiAttributeListAddInteger(&attrs, PAPI_EXCL,
"copies-default", 3);
...
status = papiPrinterAdd(svc, "ipp://server/printers/triplicate",
attrs, &result);
papiAttributeListFree(attrs);
if (status != PAPI_OK) {
/* report a failure */
}
if (result != NULL) {
/* dump the printer info */
papiPrinterFree(result);
}
...
papiServiceDestroy(svc);
papi_status_t papiPrinterRemove(papi_service_t handle, char
*printer_name);
INPUTS
handle - Handle to the print service from which to remove the
printer object.
name - Name or URI of the printer to be removed.
RETURNS
If successful, a value of PAPI_OK is returned. Otherwise an
appropriate failure value is returned.
EXAMPLE
papi_status_t status;
papi_service_t svc = NULL;
...
status = papiPrinterRemove(svc, "ipp://server/printers/triplicate");
if (status != PAPI_OK) {
/* report a failure */
}
...
papiServiceDestroy(svc);
papi_status_t papiPrinterEnable(papi_service_t handle, char
*printer_name);
INPUTS
handle - Handle to the print service on which to enable job
creation for the printer object.
name - Name or URI of the printer to be enabled
RETURNS
If successful, a value of PAPI_OK is returned. Otherwise an
appropriate failure value is returned.
EXAMPLE
papi_status_t status;
papi_service_t svc = NULL;
...
status = papiPrinterEnable(svc, "ipp://server/printers/triplicate");
if (status != PAPI_OK) {
/* report a failure */
}
Dis.
papiServiceDestroy(svc);
papi_status_t papiPrinterDisable(papi_service_t handle, char
*printer_name,
char *message);
INPUTS
handle - Handle to the print service on which to disable job
creation for the printer object.
name - Name or URI of the printer to be disabled
message - an optional reason for disabling the print queue.
RETURNS
If successful, a value of PAPI_OK is returned. Otherwise an
appropriate failure value is returned.
EXAMPLE
papi_status_t status;
papi_service_t svc = NULL;
...
status = papiPrinterDisable(svc, "ipp://server/printers/triplicate",
"because it's Tuesday");
if (status != PAPI_OK) {
/* report a failure */
}
...
papiServiceDestroy(svc);
papi_status_t papiJobPromote(papi_service_t handle, char *printer_name,
int32_t job_id);
INPUTS
handle - Handle to the print service on which the job resides.
name - Name or URI of the printer associated with the job.
job_id - Id number of the job to promote.
RETURNS
If successful, a value of PAPI_OK is returned. Otherwise an
appropriate failure value is returned.
EXAMPLE
papi_status_t status;
papi_service_t svc = NULL;
...
status = papiJobPromote(svc, "ipp://server/printers/triplicate",
12);
if (status != PAPI_OK) {
/* report a failure */
}
...
papiServiceDestroy(svc);
