Is there any way to hold the print job using CUPS API?

Question

Is there any way to hold the print job using CUPS API ? i have to code in c language and on ubuntu machine.An example could really help.

Answer 1

see the shell commands lprm and cancel

You can invoke shell commands from c using system() or sh -c (How do I execute a Shell built-in command with a C function?)

http://linux.die.net/man/1/lprm-cups https://www.cups.org/documentation.php/man-cancel.html

http://linux.die.net/man/3/system

Also see this http://www.g-loaded.eu/2005/11/10/using-a-cups-printer-from-command-line/ (commands can be used with system() or sh -c)

You can also use this, it is easier to use the shell commands: cupsCancelJob()

#include <cups/cups.h>

cups_dest_t *dest;
int job_id;

cupsCancelJob(dest->name, job_id);

If you want to delete the job (also stops printing) use cupsCancelJob2()

ipp_status_t cupsCancelJob2 (
    http_t *http,
    const char *name,
    int job_id,
    int purge
);

Parameters

http Connection to server or CUPS_HTTP_DEFAULT

name Name of printer or class

job_id Job ID, CUPS_JOBID_CURRENT for the current job, or CUPS_JOBID_ALL for all jobs

purge 1 to purge, 0 to cancel
