When changing the paper size in the print dialog box form Letter to Tabloid, the output does not automatically resize or maximize. You are forced to hit the maximize button - if that step is missed, the output is not sized properly for the paper. How do you make this happen automatically.
There is a Printing Preference option which allows for auto-maximizing when you change from one paper size to the other. It is located in the Print Menu under “Settings>Preferences”. Check the box named “Maximize on new plot area”. This value is unchecked (or turned OFF by default).
There is also a variable which controls this. It is Undefined by default:
If MS_PLT_MAX_ON_NEW_AREA is set to '1', the print size is automatically maximized when the print area is changed. This includes when a view number is selected or a fence is placed. By default, the current print scale is preserved.
You also have to uncheck: Enable Scale Preservation it is ON by default: MS_PLT_ENABLE_PRESERVE_SCALE
