Hi Ian,
Answers to your good questions:
1) If you do a zoom extents on the drawing, does it show a lot of blank space?
A1]No it does not. And there are no 'extra' entities beyond the drawing. I have trouble shooted the problem with a very simple drawing composed of a rectangle (representing the paper size) that is used to define the drawing size sent to the printer, and a couple of objects inside of the rectangle.
2) With it zoomed out, if you select all the drawing (Ctrl+A), and you have grips turned on, do you see a grip out near the edges of the screen?
A2] No
3) Seeing as you have it set as Landscape, if you tried setting it as Portrait, what would happen?
A3] Note, I have tried two approaches to printing the 24wide x 18 high drawing. The first is directly through Autocad. The drawing itself is laid out on the screen with the 24" width visually along the 'x' axis. If I print this in Autocad, using Arch-C paper settings, in Landscape mode it prints the 24" width along the lenght of the paper roll, while the 18" drawing height is along with 24" width of the paper. So this is not desired. If f I print this in Autocad, using Arch-C paper settings, in Portrait mode it prints the 24" width along the width of the paper roll, while the 18" drawing height is along the length of the paper rolll. This orientation is as desired, however the output (along the 24" width of the drawing) is cropped, as if the 24" drawing width is too large for the 24" paper roll width. I can even make the drawing be 20 wide x 18high and output it in Portrait mode and even this 20" drawing width gets cropped against the 24" paper width. One can create a custom page 18Wx24H or 24Wx18H, so that one would have to print landscape or portrait to get the 24"wide drawing image against the 24" wide paper roll, but in both cases you still get image cropping when the 24" drawing width is printed against the 24" paper width. The other approach was to first generate a PDF in Autocad. And then open the PDF in Adobe Acrobat Pro and print from there. for this case the pdf is without a doubt 24wide x 18high (you can measure it in Adobe Pro). But I still have the same above problems. YET, as posted last, I found success using the Apple 'Finder" viewer to open and print to the T520. I can also print a 24x18 image succesfully from Adobe Photoshop and from Powerpoint. So the problem seems to be in how my Apple2016LT autocad (and I had the problem with the 2015 LT as well) and how my Adobe PDF interacts with the printer. I don't have the problem with other apps.
4) How does the plot preview look?
In my earlier post, there was a screen grab of the "print' screen.... it shows how part of the drawing is greyed out, indicating that cropping will occur- and it does occur. I don't use any other sort of plot preview.
5) Have you tried creating a fresh PC3 file?
I don't think that I use PC3 files? When printing in Autocad, I just type 'plot' and proceed ... changing the setting in the Print window each time. Because I created custom paper sizes (eg, the 24wide x 18 high), I can select them, when I want, when pick the appropriate paper size.

Have you tried setting limits and printing to limits?
