Never use "Fit to Page" when printing model sheets. It doesn't make sense as the data you are printing is different in size from page to page, so fitting to page will of course alter the data. Always use the default printing, do not use "borderless", that does not work good good on Epson, of many other printers, for the reason I stated above. Set your printer back to "Default" settings. The parts you have printed so far may fit, I think probably not.....
