Trouble printing report as Text with richtext

rbuser

Hi,

I'm using the reportbuilder to make my reports.
I never had any problem with it. But now, I'm not happing

codes are print together the text.
This just happen wen I try print it as text direct to printer,
if I using grafic mode, that's ok

Can anybody help me, please

Thanks,

If you want to print text to the dot matrix printer, then print the report
to a text file and then send that to the printer. You can read the
PlainText property on the rich text control to feed the text into a memo
which is sized the same as the rich text control. Then you can print the
memo to the report emulation text file. I've attached a couple of articles
which describe this in more detail.

Tech Tip: Send TextFile to Printer
-----------------------------------------------

I designed a application that exports the report to a .txt
file using ReportTextFile device.

How can I Send the text file to the printer?

The following procedure will send the .txt file to
the printer using Delphi's TPrinter object.



uses
Printers;


procedure SendTextFileToPrinter(aFileName: String);
var
lsLines: TStringList;
lOutputFile: TextFile;
liIndex: Integer;
begin

lsLines := TStringList.Create;

try
lsLines.LoadFromFile(aFileName);

AssignPrn(lOutputFile);
Rewrite(lOutputFile);

for liIndex := 0 to lsLines.Count-1 do
Writeln(lOutputFile, lsLines[liIndex]);

CloseFile(lOutputFile);

finally
lsLines.Free;
end;


end;

Article: Printing to Dot Matrix Printers
-----------------------------------------------

Dot matrix printers are natively line and character based. Most dot matrix
printers can emulate graphical (i.e. pixel based) printing, but there is
additional overhead which degrades printing speed.

Some options for maximizing performance:

1. Use native printer fonts.

Each dot matrix printer normally has some built-in fonts. You can choose
these fonts when using the ReportBuilder Report Designer. Choose File |
PageSetup and select the dot matrix printer (or optionally use the object
inspector to set Report.Printersetup.PrinterName). The fonts displayed in
Report Designer's font drop down list located on the format toolbar will
display the printer native fonts (indicated by a special printer icon next
to the font name).

2. Vertically position and size objects in 1/6 inch increments.

A standard dot matrix printer can print 66 lines per 11 inch portrait page.
This translates to a line height of 1/6 inch. Therefore the height of each
band should be a multiple of 1/6 as should the size of the margins, the
vertical position of each object etc.

3. Keep the layout simple, avoid using graphics of any kind.

Alternatives to using the dot matrix printer driver:

1. Use the generic text printer driver.

When using the generic text printer you will need to use the courier or
courier new font and apply the layout techniques described above.

2. Use ReportBuilder's ReportTextFile device output format.

This ReportTextFile device can exports the report to a .txt file which you
can then send to the printer. Demo dm0107.pas in the main reports demo app
shows an example of printing a report to a .txt file and previewing the
results.
