Error in printing a file

surwassu · 06-07-2011, 06:13 AM

Hi Guys,
I am new to cups n trying to learn it by executing simple programs.I am trying to print a ps file through code using cupsPrintFile..The code is as follows:

Code:

#include <cups/cups.h>
#include<stdio.h>
int main()
{
int num_dests;
cups_dest_t *dests, *default_dest;
int job_id;
num_dests = cupsGetDests(&dests);
default_dest = cupsGetDest(NULL, NULL, num_dests, dests);
job_id = cupsPrintFile(default_dest->name, "/data/print.ps","my title",default_dest->num_options,default_dest->options);
//printf("\n\n\\t%d",job_id);
return 0;
}

Programs execute properly but didn't print the file .I checked error log file which is showing me following error.
[error]

Hi Sumit,
Try restarting your daemon.

Code:

service cups restart

Are you otherwise able to print files ?

Try these

Code:

# lpr filename (This will give you the default printer)
# lpr -P printer filename   (Now replace the printer name from the above command)

You might find this link useful.

hi,

The error was about connection problem with printer .I have solved it .Thanks for providing link but I want tot print the file through program not through command.

Do you have any idea about how to configure printer through cups API..?
Thanks

Isn't that just the code that Snark1994 gave you IN THIS POST on one of your other threads on this same subject?

Not to knitpick or anything, But I think if you where to post on that thread about how the code didn't properly work, You would get a more detailed reference as to why it isn't working.

I think that keeping one thread going on the same subject will yield better results, all errors can be seen and everyone will be able to assist you better, It's just more organized and you won't have to go through 4 threads all with multiple suggestions. starting a new thread for every step is just going to lead to confusion for you and confusion for others.

Of course that is just my opinion and I may be way off base mentioning it. Hope you get it figured out, Good luck.

Hi buddy,
I have wanted to clear few things.
I have checked about snark's post but u can check the date when I have posted this error in printing file post.It is posted on 07-06-2011,then I created new post on 08-06-2011 for my new problem saying reading contents from pdf file .This post has nothing to do with my previous post but u can find sneak gives me same code for that problem as a solution. That code,which any one can find on WWW.cups.org.I haven't done this intentionally ,on next time on words I will take care of that it won't happen .
Thanks & regards,
Sumit
