Configure to print directly to printer

as long as you have access rights to use the printer, you can print to it. it also depend on your network setup, if you are working in a workgroup or domain environment, as long as proper access rights has been setup, you are fine.
remember, the owner of the printer can share the printer and assign users to that printer.

If the printer has an IP address you can print directly to it.

Double-click Add Printer, and then click Next.

Click Next to run the Add Standard TCP/IP Printer Port wizard. If it asks for more information for the NIC choose jetdirect
