In course context returns css which causes the body to be blank when media="print", |
|
if printout generation is unavailable for the current resource. |
|
|
|
This could be because: |
|
|
|
(a) printstartdate is in the future |
|
|
|
(b) printenddate is in the past |
|
|
|
(c) there is an active exam block with "printout" |
|
functionality blocked |
|
|
|
Users with pav, pfo or evb privileges are exempt. |
