Dears,

I am developing a  raster driver (filter) with same code on both macOS and Linux.
In the code I flush stdout every time with a page end. I wish CUPS will send the page data to printer, so when the driver handing the next page, the printer can print the current page.
The design is good on  Linux, but on macOS, CUPS didn’t send the data, until filter exit(Check on macOS 10.10.5).

So, I wonder, if there is a way for filter to force CUPS to send the data to printer on macOS, or it just a different behavior on different OS.
