You should not be doing that.
It isn't very nice to mess with a user's windows settings.

You should ask in vcl.components.using
They could also explain to you how to use the VCL to switch printers
so you don't have to make your customers mad at you.

you must assume the person has specific reasons for doing this - and nobody 
ever said anything about having customers ....

The first time the global VCL Printer object is referenced it will point to 
the system default printer.  If you change the system default printer then 
the printer object must be changed manually.  If you have control over the 
application then you can do something like the following:

  TPrinter* printer = Printer();
  int printerIndex = printer->Printers->IndexOf(theNewName);
  printer->PrinterIndex = printerIndex;

The exact way to get the new printerIndex might vary depending on the actual 
name you have.  But in any case you need to get the index some how.

As Bob mentioned, borland.public.cppbuilder.vcl.components.using would have 
been a better newsgroup to post this question.

Part of the job of a responder in a newsgroup is to comment on an action 
that is typically problematic or demonstrates a lack of understanding of the 
issue.  It is never an assumption to believe that a "person has specific 
reasons" unless you explicitly mention that in the post (or a previous 
post).  Since you are the one asking for help it is up to you to provide the 
proper perception ... or you'll just have to deal with a perfectly valid 
response such as Bob's.

Tell that to your other program running at the time and the one which will 
be run tomorrow, both which will now print on the wrong printer.

However, given that at the time you thought this might have been an OS issue 
this was a valid group as well.
