Q: Update HT3669 bugs
On 9/11/16 update HT3669 was loaded on my Mac OS X El Capitan 10.11.6 and I haven't been able to print since. How do I undo this update? Also my Time machine is off and I can't turn it on.

To remove an OS or update, you must boot into Recovery and restore from the backup you made prior to installing.

In this case, you can just try resetting the printing system. OS X El Capitan: Reset the printing system
