regarding sales order bulk printing

dear sir,

1.here i have an issue which is i want to take printout of sales order.i go for va02 and giving output type,issue output to there it shows only the print preview of that salesorder and no print option is availabile(print option is there but it turns into grey).what changes i need to make so that the print option is configured to get the printout of salesorder.?

2.if i want to take the printout of salesorder in bulk is there any tcode for that(like vf31 for bulk invoices).if it is there what changes i need to maintain to get printout of salesorder in bulk?
