Printing to 2 printers at same time problem.

rbuser

I have implemented the code found in an example posted in this newsgroup.
Everything works great, except for one printer. We have 4 HP 2200d's that
are all configured the same. The problem is that one of them always kicks a
blank page at the end when I use the multiple printer code. If I just print
to the same printer all by itself without using the multiple print code,
then it doesn't kick the extra page. Here is the code I am using. Anyone
ever seen this behavior.


if PrintTwoCopies then
begin
FirstPrinterDevice := TppPrinterDevice.Create(Self);
FirstPrinterDevice.Printer.PrinterName :=
PrinterToReportBuilder(Ini.ReportPrinter);
FirstPrinterDevice.Publisher :=
frmPickTicketRpt.repPickTicket.Publisher;

SecondPrinterDevice := TppPrinterDevice.Create(Self);
SecondPrinterDevice.Printer.PrinterName :=
PrinterToReportBuilder(Ini.BackupPrinter);
SecondPrinterDevice.Publisher :=
frmPickTicketRpt.repPickTicket.Publisher;

try
FirstPrinterDevice.StartJob;
SecondPrinterDevice.StartJob;
frmPickTicketRpt.repPickTicket.PrintToDevices;
finally
FirstPrinterDevice.EndJob;
SecondPrinterDevice.EndJob;
FirstPrinterDevice.Free;
SecondPrinterDevice.Free;
end;
end
else
begin
frmPickTicketRpt.repPickTicket.PrinterSetup.PrinterName :=
PrinterToReportBuilder (Ini.ReportPrinter);
frmPickTicketRpt.repPickTicket.Print;
end;

Thanks in advance,

Also, needed to add that I look at the spool files and they are 2 different
sizes, even though they are both using the same printer drivers... Odd.

Hi Rick,

The code you have seems to be ok, and I have never seen this behavior
before. As an alternative, take a look at demo 122 (dm0122.pas) located in
the RBuilder\Demos\1. Reports\... directory. This is a slightly different
approach to take to print to multiple printers at once, but is proven to
work so it may be worth a try.

Thanks for the response. I found it to be somewhat of a driver setting
issue. Some printers were setup to use Soft Fonts and others to use
hardware fonts. The Use Device Setting seemed to work great and the Soft
Font printed the extra blank page. I changed them all to Device Setting and
all is well.

Thanks
