force a 'pause' or 'sleep' between print jobs

Hi All,

I am involved in a project where we need to have cretin print jobs sent

to specific trays. If these print jobs are sent individually they print

to the correct trays. if they are sent together, that is in quick

succession, they print to the wrong trays. we have found that if we send

these jobs together and pause the print queue and pause each individual

print job the release each print job separately from the print queue

they print fine.

Is there a way to setup an automatic 'pause' or 'sleep' between print jobs?

Windows Server 2003 R2

multiple printer type but all HP's

Thanks in Advance
