Do you get the same result when you print to a plain paper printer as a test? (That will help us know if the issue is specific to the thermal printer or not.)
Thank you for your post.
It is printer independant. It is right there in Browse mode, Preview mode, the PDF AND when printed.
Changing the printer makes no difference to the Browse Mode, Preview Mode or PDF except that if i set it to A4, I still get the grey block, but not all the way across the page. Only as far as what the (whatever it is called) layout active area is.
I FOUND THE PROBLEM !!!! It's the darn THEME and not the STYLE of the parts.
It is as if, when going to Preview, Print or PDF, Filemaker Pro Advanced 12's NONE FILL (ALL STYLE REMOVED) is in fact light grey and NOT nothing.
I changed theme to Basic and now all the empty space is white again and the printer senses the correct cut !
This raises a new question .... how to create or edit themes ?? Some research ... or a different post.
Phew ! Too many hours were wasted on this.... I hope this post saves someone else the time !
Are you using FileMaker 12.03, if you have 12.02 or 12.01, download the free updater and see if that makes any difference.
Also see if clearing the Delineate option in Layout Setup... makes any difference.
Note that changing thems produces a small, but irreversable increase in your file size, so don't experiment with a lot of themes in your developmente copy, use a copy for testing that you then discard.
