I don't know what "better" in specific you mean, but in the few cases I need to print over many sheets for simulating a bigger format as my small printer can handle, I just use Acrobat ... even the free reader. Just have a look at the printing dialog.

Yes there is.

The decades old Unix commandline program, available for Windows and OS X too.

https://www.imagemagick.org/script/index.php

And some tutorials.
http://www.imagemagick.org/Usage/crop/

You can with that even generate a script that does wanted crops just by dropping a file on it and then output all to pre-defined directory etc.

That I used decades ago to edit a gigapixel files with a 233Mhz Pentium with a 64MB, then 128MB and finally 256MB RAM.

All you needed to do was to slice the original image file to tiny pieces that you can edit.
Then edit each of the file as you want by retouching etc. And then finally you made copy of the original with small rescale for color adjustment and print previews, and then you applied that adjustment as batch process to all pieces and finally you stitched all the sliced parts back to original one.

In Photoshop you can place guides (dragging them from the ruler bar) to denote the slices of the full-sized image.  Then select the Slice tool (it is in the same palette as the Crop tool) and select "Slices from Guides" in the toolbar.  Use the Save For Web (Legacy) export option and configure the image format and slice options.  You will get a folder with the slices in it.

If you plan on printing each slice to a certain size, you would want to upres the original file to the proper size and resolution (in PPI) so that each slice conforms to the desired output size.  For example, let's say you will want 3 slices wide and 2 slices tall and each slice will be a portrait-oriented 8"x10" and you want 300 PPI prints.  Then the total dimensions of the unsliced file should be 24"x20" - if you want to print at 300 PPI, then the resolution of the upres-ed image must also be at 300 PPI before you slice it, i.e., the original image needs to be 7200 pixels wide [24 inches x 300 PPI] by 6000 pixels tall.  Otherwise you will have to upres each slice individually.

Hi,

Qimage offers a Poster output mode that splits a single image over multiple output pages. It's simpler to do that I can explain here, but you just specify the required output size and if it's larger than the available paper size it will automatically offer to use as many pages as needed. The excellent resampling quality and output sharpening will get the most out of the source image, with minimal effort (no need to slice before printing).

Cheers,
Bart
