cups: update permissions for HP printers (load firmware) |
| 9 |
|
| 10 |
Update the cups module with some permissions needed to run HP |
| 11 |
printers (in particular to be able to load firmware on those |
| 12 |
printers that need it every time they are connected). |
| 13 |
|
| 14 |
The permission to execute shell scripts has been removed in |
| 15 |
this new version, as this is not required. |
| 16 |
|
| 17 |
Compared to previous versions, this new version creates a |
| 18 |
specific hplip pty (as suggested by Christopher PeBenito). |
| 19 |
|
| 20 |
Here is the list of printers that require firmware loading: |
