Choose fronted printer.

eyal_alsheikh — Tue, 03 May 2005 06:28:28 GMT

Hi,

I need to print several word documents one after another, but not to the default printer. Todo that, I open each document, print it and closing it.

I use the Interface I_OI_DOCUMENT_PROXY methods:

- OPEN_DOCUMENT_FROM_TABLE

- PRINT_DOCUMENT

- CLOSE_DOCUMENT

The problem is that I only succeeded to print my documents to the fronted (user windows) default printer.

Is there a way to change the windows default printer for my application before printing?

I looked for a method in class CL_GUI_FRONTEND_SERVICES

but didn't find one.

Thanks from your time,

Eyal.

Hi Eyal,

Go to the menu option System~~>User Profile~~>Own Data. On the screen that follows, go to the Defaults tab and specify the Output Device to the value that you like.

Is that what you're looking for ?

If the printer is defined in the SAP system you can get the same from table

TSP03

and then you can direct your prints to that particular printer.

also check out this FM

RSPO_FRONTEND_PRINTERS_FOR_DEV

Hi,

Thanks but I required that the user will select the printer at runtime,

before the documents send to the printer.

Because I open a Word document and print it the selected printer is taken from the Windows printer definition, like when I open my Word application from the desktop, regardless the printer defined in the SAP system (in my opinion).

can you explain the process bit more clearly.

my understanding is that you thru an abap program you open documents and print it right?

Where does the user interaction comes here?

or do you want the ability for the user to choose a front end printer before they run the abap (as selection value)

Hi Eyal,

Like Raja, even I'm a bit not clear with your description of the requirement. But as far as I know, you will not be (and should not be) able to change the default printer for Windows for any user. Don't you think that is going a bit too far ?

But if the user wants to be able to select the printer which has to print the word document, then instead of using the print button on the toolbar in the word document, the user will have to choose the menu option File-->Print from his word document. That will give him a pop-up which has got the printers defined in Windows. He can choose any printer from there. The toolbar button for print in Ms-Word does not give this pop-up, it automatically prints at the default printer.

Anand Mandalika.

Eyal,

Are you trying to print to the Windows default printer ?

If this is what you want to do, you can specify the output device as LOCL. This will print it on which ever printer is set as the default printer for that user.

PS: Remember 2 Reward the answer that helped u solve your problem.

Thanks,

The process is should be as follow:

- The user gives a range of documents number in the select option and has a parameter to choose a printer to print them.

- For each document I:

- fill an Internal table in 'RTF' format ( the document content ).

- Open the document from the internal table,

- Set the printer in the user fronted ( like in the printer dialog ) - This my problem,

- Print the document,

- Close the document.

- Next document.

Because I am Opening and Closing the document in the screen PBO the user doesn't see the documents on screen so he can't choose the printer himself in the print dialog.

Hope it is better now,

Eyal.

did you try setting the prompt_user parameter of PRINT_DOCUMENT method?

to get the list of front end printers installed you can use the following code.

 CALL FUNCTION 'RSPO_LIST_FRONTEND_PRINTERS'
        destination 'LOCAL_PRINT'
          TABLES
            list    = list
          exceptions
            others  = 1.

Thanks Raja,

Unfortunately it does not work. The prompt_user

parameter opens the dialog printing before the document is sending to the printer.

It does not good for me because the user need to choose the printer once at the selection screen and not for each document.

Please paste the code here.
