Frontend printing using SAPsprint

Currently we are using frontend printing using SAPlpd. This method is not recommended anymore and we have issues with it. So we would like to use SAPsprint instead.

Here is a typical scenario:

1- Web AS running on a UNIX box in location A

2- SAP GUI on Windows XP in location B

3- Print server running Windows 2003 server in location B

My question is: where should we install SAPsprint? What needs to be changed on Web AS? Do we still need SAPlpd on Windows XP workstations?

Cheers,
