Anyone know if it is possible to control the printing in a browser? I'm just
pondering converting an internal utility to EWB, and it prints labels, so it needs
to be sort of precise. If it isn't even practical I won't start, but if it was...

This may not be practicle, but might be worth a look :

Thanks. I had considered generating PDF, but not sure how practical that is
for the user to print from either.

Hi Mathew

Not sure if you are aware that Fast Reports "Enterprise" has Components
for web-applications.

Version Matrix here ...

This looks hopeful, though you'll get the browser headers I guess. I can probably
fix that with a custom browser I suppose...

I use ReportBuilder Enterprise (Pro can do it too) to generate a PDF.

rptMain - it the Report component.

In this a snip it - it is MSSQL UniDac  (DevArt) backend with RealThinClient http server...


function TdmUniSQL.EWBPrintInvoice(Query: TRtcHttpValues): string;
var
 HD: TppPDFDevice;
 ST: TStringStream;
 i : integer;
 iWebTimeId : integer;
begin
//  Log('EWBPrintInvoice ', 'EWB');

 iWebTimeId := 0;    
 
 for i := 0 to Query.ItemCount - 1 do
 begin
   if Uppercase(Query.ItemName[i]) = 'WEBTIMEID' then
     iWebTimeId := StrToInt(Query.ItemValue[i]);
 end;

 tbTimeInv.Close;
 tbTimeInv.FilterSQL := 'WebTimeId=' + IntToStr(iwebTimeID);
 tbTimeInv.Filtered := True;
 tbTimeInv.Open;

 if qTimeOther.Active then
   qTimeOther.Close;
 qTimeOther.ParamByName('PID').AsInteger := tbTimeInv.FieldByName('PositionsID').AsInteger;
 qTimeOther.Open;
 
// ******* Here is the Report Builder part

 ST := TStringStream.Create('');
 HD := TppPDFDevice.Create(Self);
 HD.OutputStream := ST;
 HD.Publisher := rptMain.Publisher;
 rptMain.PrintToDevices;

 result := ST.DataString;    // Send Back PDF

 qTimeOther.Close;
 tbTimeInv.Close;
 
 FreeAndNil(st);
 FreeAndNil(hd);
end;


I have a provider routine that obtains the request ... this is specifically doing the response for the Inoivce

       Conn := FConnections.LockConnection;
       try

         // Setup PDF Response....

         Response.ContentType := 'application/pdf';
       
         Response.HeaderText :=
              Response.HeaderText +
                RtcString('Access-Control-Allow-Origin: *' + #13#10) +
                RtcString('Cache-Control: must-revalidate, post-check=0, pre-check=0' + #13#10) +
                RtcString('Cache-Control: public' + #13#10) +
                RtcString('Content-Description: File Transfer' + #13#10) +
                RtcString('Content-Disposition: attachment; filename=Report.pdf' + #13#10);
         
         Write(RtcString(Conn.EWBPrintInvoice(Request.Query)));    // ****** Calling the EWBPrintInvoice
       finally
         FConnections.UnlockConnection(Conn);
       end;
     end;

Nice thing about Report Builder - just change the device (  HD: TppPDFDevice; ) to the Excel, or Word or HTML device and you can send your report back anyway you probably need to.
