21 | class JobPriority(Attribute): |
---|
22 | """4.2.1 job-priority (integer(1:100)) |
---|
23 | |
---|
24 | This attribute specifies a priority for scheduling the Job. A |
---|
25 | higher value specifies a higher priority. The value 1 indicates |
---|
26 | the lowest possible priority. The value 100 indicates the highest |
---|
27 | possible priority. Among those jobs that are ready to print, a |
---|
28 | Printer MUST print all jobs with a priority value of n before |
---|
29 | printing those with a priority value of n-1 for all n. |
---|
30 | |
---|
31 | If the Printer object supports this attribute, it MUST always |
---|
32 | support the full range from 1 to 100. No administrative |
---|
33 | restrictions are permitted. This way an end-user can always make |
---|
34 | full use of the entire range with any Printer object. If |
---|
35 | privileged jobs are implemented outside IPP/1.1, they MUST have |
---|
36 | priorities higher than 100, rather than restricting the range |
---|
37 | available to end-users. |
---|
38 | |
---|
39 | If the client does not supply this attribute and this attribute is |
---|
40 | supported by the Printer object, the Printer object MUST use the |
---|
41 | value of the Printer object's 'job-priority-default' at job |
---|
42 | submission time (unlike most Job Template attributes that are used |
---|
43 | if necessary at job processing time). |
---|
44 | |
---|
45 | The syntax for the 'job-priority-supported' is also |
---|
46 | integer(1:100). This single integer value indicates the number of |
---|
47 | priority levels supported. The Printer object MUST take the value |
---|
48 | supplied by the client and map it to the closest integer in a |
---|
49 | sequence of n integers values that are evenly distributed over the |
---|
50 | range from 1 to 100 using the formula: |
---|
51 | |
---|
52 | roundToNearestInt((100x+50)/n) |
---|
53 | |
---|
54 | where n is the value of 'job-priority-supported' and x ranges from |
---|
55 | 0 through n-1. |
---|
56 | |
---|
57 | For example, if n=1 the sequence of values is 50; if n=2, the |
---|
58 | sequence of values is: 25 and 75; if n = 3, the sequence of values |
---|
59 | is: 17, 50 and 83; if n = 10, the sequence of values is: 5, 15, |
---|
60 | 25, 35, 45, 55, 65, 75, 85, and 95; if n = 100, the sequence of |
---|
61 | values is: 1, 2, 3, ... 100. |
---|
62 | |
---|
63 | If the value of the Printer object's 'job-priority-supported' is |
---|
64 | 10 and the client supplies values in the range 1 to 10, the |
---|
65 | Printer object maps them to 5, in the range 11 to 20, the Printer |
---|
66 | object maps them to 15, etc. |
