If you are certain that you have downloaded and installed the Link Removed - Invalid URL for Windows 7 for that printer on the laptop machine. You may want to try adjusting the driver properties, try disabling bi-direction support if there, or disabling enale advanced printer features, under the advanced tab of printer properties, under the sharing tab make sure you check the box that says Render print jobs on client computers.
Additionally if you used the network printer wizard to intall the printer on the Win7 machine, you may try deleteing it and re-installing as a local printer and see if that helps.
Try this
Open Devices and Printers
Select add printer near the top menu bar
