Too Many Devices attached - Can add but how to remove?

rbuser

We have a custom viewer, and also print the same report
one page or all pages - when we go through the process we
assign the publisher
FPrinterDevice.Publisher := FMedicalReport.Publisher;
FMedicalReport.PrintToDevices;

but if we do it several times it winds up with say 4 devices
in the devices array in the RB source code. This I believe
then causes the RB not to print. It is complicated too follow.
The bottom line is it will print at first but not after a while.
When I say print I mean it appears to pour the report into
the printer but it nver comes out...

Because we wind up with 4 devices attached
to the printer device I assume its getting confused
and would like to remiove all the attached devices - but
I can find no command to do this

help -

D5 RB 6.03

There should only be one FPrinterDevice object, do you create one everytime
but not free it? Make a call after PrintToDevices:

FPrinterDevice.Publisher := FMedicalReport.Publisher;
FMedicalReport.PrintToDevices;
FPrinterDevice.Publisher := nil;

This way everytime you assign a report to print, you can print it and then
disconnect the device.
