Re: lpr: order of print requests

[Lorenzo Iania]

I don't know if I make any strange mistake, but I have done the following simple thing.     File p.c :   #include <stdio.h>   FILE    *fp             ;   main() { register int    i       ;   for (i=0;i<1000;i++)         {         fp=popen("lpr -Plp","w");         fprintf(fp,"Richiesta N. %d\n",i);         pclose(fp);         } } then   cc -o p p.c   ./p   the result of lpq after this is:   waiting for lp to become ready (offline?) Rank   Owner      Job  Files                                 Total Size 1st    root       33   (standard input)                      15 bytes 2nd    root       30   (standard input)                      15 bytes 3rd    root       35   (standard input)                      15 bytes 4th    root       36   (standard input)                      15 bytes 5th    root       29   (standard input)                      15 bytes 6th    root       31   (standard input)                      15 bytes 7th    root       37   (standard input)                      15 bytes 8th    root       38   (standard input)                      15 bytes 9th    root       39   (standard input)                      16 bytes 10th   root       40   (standard input)                      16 bytes 11th   root       41   (standard input)                      16 bytes 12th   root       42   (standard input)                      16 bytes 13th   root       32   (standard input)                      15 bytes 14th   root       34   (standard input)                      15 bytes 15th   root       56   (standard input)                      16 bytes 16th   root       57   (standard input)                      16 bytes 17th   root       43   (standard input)                      16 bytes ....etc   As you can see, the first on the queue is Job 33, while the second is 30 and so on .... The sizes are irrilevant because they are the same. For this reason, and for similar problems, it is desiderable that the order of the requests is the same. I think that must be a chance to respect the order of the requests to avoid situations like this.   Thanks.
