Print in draft mode
You can use Draft Mode Printing to print contact sheets and quick drafts of a photo. In this mode, Lightroom uses cached photo previews when printing. If you select photos that haven't been fully cached and print them using Draft Mode Printing, Lightroom sends their thumbnail data to the printer, and the print quality of those photos might not be what you expect. Sharpening and color management controls aren't available using Draft Mode Printing.
In the Print Job panel of the Print module, select Draft Mode Printing.
