    Sometime last year, MS changed a character set and updated a lot of fonts to support some new Kazakstan currency thing, and I know that caused no-print issues with Crystal Reports. Other than that, I've not heard of any such errors from our users.

    Interesting. I guess we were saved by still running Windows 7 Enterprise.

    Lars Fosdal​ this affects windows 7 too. Make sure to skip KB3177725 for now. Windows 10 has a different KB number, I think it's mentioned in the forum post.

    I have same problem some days ago.. In my case, I resolve by forcing re-create TPrinter global object inside Vcl.Printers:

    ..Vcl.Printers.Printer.BeginDoc;
    ..try
    ....//ommited code
    ....Vcl.Printers.Printer.EndDoc;
    ..finally
    ....Vcl.Printers.SetPrinter(nil).Free;
    ..end;

    Apparently there's a bug in Vcl.Printers that makes something become "stuck" in memory

    it is due to caching the printer DC more here
    https://quality.embarcadero.com/browse/RSP-15648

    1) this is driver specific
    2) I guess doing a Printer.Refresh; BEFORE Printer.BeginDoc will also work, basically anything that will re-create the DC. The bug report above also has a WA.
    3) the update that broke this was because of security fixes for kernel objects
    4) there is a link to the MS "forums" in the above bug report that discusses problem.
