ADDITIONAL SYSTEM INFORMATION :
NetBeans 8.0.2 / JDK 1.08 / JFX 8.03. I made test projects with JFX13, 12, and 11 linked and they all have the problem. Cannot print forms with 3/4 inch margins! I am running Apache 12.0 building "Simple JFX Maven" projects. Im running on MacOS 10 but your dropdown only shows Windows??!!!??

A DESCRIPTION OF THE PROBLEM :
I have a program that prints forms and works correctly on NetBeans 8.0.2 / JDK 1.08 / JFX 8.03. It reports a page size of 8.33" x 10.83", Lmargin=0.16,Rmargin=0, Tmargin=0.16,Bmargin=0. It prints Avery label forms correctly. I installed ApacheNetbeans (whew!!) and ported (copied) the files to a new JFX project and it runs great but printing is off. Investigation shows I cannot set margins smaller than 0.75" and this is a bug on this printer. The App sets margins to .5" all around and this JFX cannot do it.



REGRESSION : Last worked in version 8u251

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Make a simple app that makes a pagelayout layout with margins < .75" and print that layout parameters to see the discrepancy. You can set margins > 1" but that's not enough??
I checked the bugdatabase and apparently JFX 8 had a similar problem with this method (JDK-809580 and others)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Whatever margin you set that's legal, meaning it is GREATER than the HARDWARE_MAXIMUM limits given by the printer.
ACTUAL -
Cannot set margins < .75". My printer almost prints to the paper's edge so this is wrong. Besides , it works with the old JFX 8!!

CUSTOMER SUBMITTED WORKAROUND :
Unfortunately NONE. For now, use old development tools that work correctly.
