When printing, I can't seem to find the scheduler in the print dialog box. How do I enable print scheduling in 10.9? I remember in at least 10.5 it being one of the options in the print dialog.
Print Job scheduling was removed in OS X 10.7 Lion. As a workaround, you can pause the printer, print what you want then continue the printer.
You can provide feedback to Apple regarding this on the following page:
There is a application called handyPrint.
I recommend it since it will also activate the AirPrint mode for almost any printer, which is very handy feature.
