I have had this problem for many years with JMP. Basically, it will not allow me to adjust text in any meaningful way when I print . Everything wants to print out on 8-1/2 x 11" paper. Even when I output to a printer that has 36" roll paper, I can't get meaningful scaling, have no control over pagination, etc. The only workaround that I have found is to copy the output as a jpg and dump it in Excel. Use Excel to adjust pagination and run the printer drivers from there. Is there a reason that the printer dialog box in JMP doesn't give me normal options for scaling and adjusting paper size similar to every other program I run on my Mac? Even when I go to the page layout dialog, it doesn't work.
I am using JMP 11.2.1 on a Mac Air but this has been a perennial problem for many years for me on either PC or Mac environments.
