Question: Put the size by default of plot 2d inside maple.ini

I am sure that this question must be answered. But when I do a search in the "Search" box, I always receive a page where it  is mentioned that there is an error of generating the page.  So this has been the case for more than a month, or maybe more. I don't know why this is happening.  So that is the reason why I ask a question here.

I would like to put an entry in the file maple.ini so that each time I do the command "plot", the size of the plot in the document will be a size=[300,300] in pixels.  That is supposed to give a plot of 8 cm by 8 cm.  So when I print the document, which will be the size of the plot on the printed page.  I want to do that because if I do not modify the size of the plot by default in the document, it takes up too much space in the page.  I want to do it in maple.ini so I don't have to do it manually each time I plot a function.

Thank you in advance for your help.
