Hi,

We are having difficulty printing the drawings on our HP DesignJet T120 plotter printer, we have tried different configurations, but in none of them the software prints, I
would like to know if there is any limitation of Intelicad in this regard.

There's no limitation in CMS IntelliCAD because CMS IntelliCAD uses the Windows printer driver for HP Designjet T120 printer.
You need to contact HP so that they provide you an updated driver or a fix for that.
