Characters are Printed Incorrectly
If characters in your document are printed out incorrectly, for example with the # character substituted for special characters, check these possible sources of error:
You can reset the character set buffer used by the spool system by entering transaction SP12 (Temporary Sequential Objects Administration). Then choose Character sets ® CS conversion buffer CCC ® Invalidate CCC.
You can check the SAP character set definition in transaction SPAD (Spool Administration). Check that the character set specified in the printer device type matches the printer character set as documented in the printer handbook. (The printer character set is usually specified in the Printer initialization action in Device initialization, transaction SPAD. Use the DINA4 or INCH12 Device initializations for the printer type in question as your guide).
