how to cut a large image in pieces in photoshop cc without exporting to web

thanks, but this is not the issue!
I want to save multiple images from one original image - maintaining high quality resolution

I know it is exist some plugin or program to do that,..unfortunately not remember where ,   let you know if I find something.
Meanwhile I will use a rectangle selection in combination reverse selection,...you shouldn't  loose no pixels.
Our printer doing that automatically, by "nesting " large images. It is Durst Thea, printing on photographic paper.

thanks, I have been looking for a plugin: but none working..
Actually I do need to save the images individually

If you select it and do from menu Image/crop, save it , then undo, reverse selection .....should work

Just do it manually using guides, selections and copy/paste. Also, most printers will auto-tile a print if it's too large for the paper...

In PS Save As> Photoshop PDF. Open the PDF with Adobe Reader and follow the below instructions if printing to a locally attached printer:

thanks, but it's not a print issue. Am looking for a way around to use the slice tool and save individualy with original resolution - not export for web

Use can simply use the guide layout manager, then copy/paste the sections of your image...

it doesn't allow for complex cuts as the slice tool...

not sure what you mean... the slice tool only creates rectangles?
