Purpose

Here is a Java Bean from Casey Bowden to get back print features lost in Oracle Reports  converting to web environment.

Direct Print

I. Problem One:

Point Of Sale (POS) clients is slow to print.

 

After converting reports from client/server to the web environment, OraRRP utility was used to print reports directly to client’s default printer, without being prompted with a print dialog. Even though OraRRP works as advertised, it does not meet the speed required for a POS terminal.

 

Solution:

In my experience with DirectPrint JavaBean, the time to print a receipt reduced from 12 – 14 seconds to 2 - 3 seconds. Also, DirectPrint JavaBean is downloaded and cached to the client machine when client accessed form that calls for DirectPrint JavaBean.

 

II. Problem Two:

OraRRP utility does not allow printing to named client printer.

 

Because of architectural change from client/server to web, knowledge of the client printers was lost since Report Server resides on the middle tier where knowledge of printers is loaded.

 

Solution:

With DirectPrint JavaBean, programmers can send PDF report output to named client printer. This feature can also be used to send a single report to multiple client printers that are either local or on the network. The exact printer name is required.

 

Conclusion:

DirectPrint JavaBean can be used to restore some print features lost when converting reports from a client/server to web environment.
