Setting another printer problem

rbuser

Hi all,

have such question: we use ReportBuilder, and we use several printers in our
application. Depending on whatprinter is associated with report we set it.
in such way:

Report.PrinterSetup.PrinterName := ' e.g. Leo\\HP 1200';

but this causes problem when running this line first time for another
printer - it takes many time. from 5 to 30 seconds (we have different
results in different networks and printers). printing report next time
without leaving program takes about 20 msec on this line.

any suggestions?

Thank you,
Eug

When the printer name is assigned, the entire print driver is loaded.
Sometimes this takes times, especially on network printers. However, once
the driver is loaded, settings for the printer are saved within the
application, so that subsequent printing to that printer will be faster. If
it takes a long time to retrieve the DC, then there's not much that can be
done for the speed, since the DC must be retrieved for each individual run
of a report. Usually though, it's the initial load of the print driver that
takes time.

Of course, once you shut-down the application, all RB caches are freed. I
don't think there's going to be a way to make it faster between runs of the
application.

To make it faster within a given application instance, you could dedicate a
report to the printer it is assigned to. Then use LoadFromFile or
LoadFromDatabase to load the definition you want for the given printer.
With this technique you would store a list of reports, one for each printer
needed.
