Using the Printers Unit in Delphi

I want to access the Printers Unit in Delphi XE7. I am not able to do this, because „the Printers Unit cannot be resolved“ as shown on this image:

As a beginner in Delphi, I don’t know what to do. Don’t judge me. Is there a way of adding a reference or something? Thank you.

Solution

  • In Delphi XE2, RTL/VCL/FMX unit names were updated with Unit Scope Names. So you have to either:

    1. use fully qualified unit names in your uses clause, like Vcl.Printers.

    2. go to Project Options -> Delphi Compiler -> Unit scope names and make sure Vcl is listed, then you can use just Printers in your uses clause.

    A new Vcl project has the following default Unit Scope Names:

    Winapi;System.Win;Data.Win;Datasnap.Win;Web.Win;Soap.Win;Xml.Win;Bde;System;Xml;Data;Datasnap;Web;Soap;Vcl;Vcl.Imaging;Vcl.Touch;Vcl.Samples;Vcl.Shell`
