Printing: print prepared binary stream with SAPWIN

Hi .

We have a lot of different documents(MS Word, MS Excel, TIFF, PDF etc.) stored in DMS.

Now we need to print them from SAP applications using SAP printers.

For that we have an external conversion server, that could convert files to any print stream data (PCL, PLC2, PCL5, Postscript, even simple PDF).

If I use printer with simple device type (e.g. Sapscript driver is HP LaserJet PCL4/PCL5) , I just convert necessary docs into the PCL output, create programmatically a new Spool request with format G_RAW and BIN content and add PCL output to it. And this way works good. But not with SAPWIN device type.

Does anybody know, if it's possible to print prepared binary stream (PCL, Postscript or other format) using printer with SAPWIN device type? And if yes, how should I create Spool request?

Thanks in advance.
