Now while editing the same GPO, go to Computer Configuration > Policies > Admin Templates > System > Group Policy and then enable the 'Configure user Group Policy loopback processing mode' and from the drop down choose 'Merge'. Tick the box to 'Set this printer as the default printer' and optionally 'only if a local printer is not present' if that's what you want. This is more of a pain to get it to become the default printer, there are some ways using a combination of group policy and applying additional registry settings but I would say the simplest way is this: Go to group policy management on DC, create your new GPO and edit it, User Configuration > Preferences > Control Panel Settings > Printers, right click in the main window and choose New > Shared Printer, leave the action at Update, put in the shared printer path (\\ServerName\Shared Printer Name', you can browse for it with the button). You didn't say if this was a shared printer installed on a print server or just a stand alone network printer with an IP address assigned.
