3dfe78b3 | 27 | * The system management functions cover disk and power management which |
1deb86fd | 28 | * are primarily used for portable computers. |
09ec0018 | 29 | * |
3dfe78b3 MS |
30 | * Disk management involves delaying the write of certain configuration |
31 | * and state files to minimize the number of times the disk has to spin | |
1deb86fd | 32 | * up or flash to be written to. |
3dfe78b3 | 33 | * |
8072030b | 34 | * Power management support is currently only implemented on macOS, but |
3dfe78b3 | 35 | * essentially we use four functions to let the OS know when it is OK to |
10d09e33 | 36 | * put the system to sleep, typically when we are not in the middle of |
8072030b | 37 | * printing a job. And on macOS we can also "sleep print" - basically the |
1deb86fd MS |
38 | * system only wakes up long enough to service network requests and process |
39 | * print jobs. | |
