xojo plugin for to print in silent mode for Linux

Hi I bought the plugin class NSPrintInfoMBS of Xojo for Mac, there is a class for printing in silent mode for Linux? Or if someone can give me a class for a similar “NSPrintInfoMB”, so you can print in silent mode.

print silent?

Doesn’t OpenPrinter function not work without dialog?

no, it doesn’t, i tryed that function on linux without dialog, when i use the OpenPrinterDialog, the setupstring returns empty, so i can’t pass the data to the OpenPrinter, and make silent print
