printUnformatted
printUnformatted(text: String): Integer updating;
The printUnformatted method of the Printer class takes unformatted print text and passes it to the printer, bypassing the Windows Printers Control. This method enables you to output text to a dot matrix printer; for example, using your specified page depth.
Use the text parameter to specify the unformatted text that is to be printed.
You must embed all control commands that you require in your parameter string; for example, top-of-page, carriage return, line feed, and so on.
Unpredictable results will occur if you mix print and printUnformatted method calls within the same print task.
This method is compatible only with dot matrix, daisy wheel, or a printer that is capable of printing a single line or single line feed. It does not work with LaserJet printers, which must print a page at a time. An exception is raised if the method fails.
The following example shows the use of the printUnformatted method.
vars
text : String;
loop : Integer;
printer : String;
begin
// Set the printer to the IBM Proprinter
printer := 'IBM Proprinter XL';
app.printer.setPrinter(printer);
// Set page depth to 3 inches - don't bother setting up the documentType
text := #'1b 43 00 03';
app.printer.printUnformatted(text);
// Print 4 * 4 labels
loop := 1;
while loop < 50 do
loop := loop + 1;
text := CrLf & CrLf & CrLf;
app.printer.printUnformatted(text);
text := ' 100831.7 100831.8
100831.7 100831.8 ' & CrLf & CrLf;
app.printer.printUnformatted(text);
text := 'Sockburn Sockburn
Sockburn Sockburn' & CrLf & CrLf;
app.printer.printUnformatted(text);
text := '123456 123457
1234568 1234569 ' & CrLf & CrLf;
app.printer.printUnformatted(text);
// Skip to top of page ( 3inch page );
text := #"0C";
app.printer.printUnformatted(text);
endwhile;
app.printer.close;
end;
