illustrator not printing to scale

Hello @lanny47,

I hope Brad's suggestions helped resolve the problem. If not, kindly share screenshots of the print settings used in Illustrator and in the Epson driver settings, a public link to a sample file after uploading it to Dropbox/Google Drive/etc. and a photo of the output print so we can better assist you.

Looking forward to hearing from you.

Thanks,
Anubhav

That increase is 4% which is Epson's usual increase for borderless.

Can you show us a screen grab of the paper size you have selected in Page Setup. (You didn't say you created a Custom one).

Also, there are a couple more places you have to check for settings. Even if you areusing a Custom Page size with set margins, and even if you are printing at 100% in Illustrator's Print Dialog, the P700's driver has settings that may conflict with this: particularly:

@lanny47 were you able to figure this out yet?

I have an epson 7840, I sometimes will add trim marks to my files because I do create bleeds in some of my files. Not only that, it sound like my bounding box. Also check to see you are changing the scale or fit to page to print is on. 

Is there maybe a setting turned on in the printer driver that overrides Illustrator's settings?
