Getting an extra page (Blank sheet) out while printing from SAP

Hi Gurus,

Please help me in trouble shoorting this issue

We have an HPLJ 8000n series printer which is sending out an extra paper (blank sheet) at the end, after each print request from SAP.

Is there any setting where we can restrict this

We are on SAP Version 4.6c and OS - AIX

Thanks in advance
