Margin option support for printer api

[kailniris]

Can we have margin option support for printer api please?
I created an invoice printer app and everything works flawlessly with the printing api expect that I can't change margin options. I found out in the app Preferences file there is 2 options regarding to this.
"marginsType":3 // 0 is for default margin, 1 is for no margin 2, is for minimal margin, 3 is for custom margin
'customMargins': { 'top': 12, 'right': 12, 'bottom': 12, 'left': 12 }

Can you please upgrade the print api with margin option support?

Tested the new build, everything works fine except the 'marginsType': 2 (Minimum) it works same as the 'marginsType': 1 (no margin).
