My default IP on my SMC was 192.168.2.1, I know other models are different.
What you do is go to your Control Panel > Printers > Add Printer
- Select Local Printer but uncheck the Autodetect Printer and Next
- Create a new port, type of port is Standard TCP/IP port
- Printer name or IP address, enter your router's IP address (i.e. 192.168.2.1) That's the same number from the Gateway field when you used the ipconfig command
- The box below should automatically be filled out for you, Next
- Choose a custom Device Type and go to Settings
- Choose LPR, under queue name, you need to read the manual to find out the exact name (i.e. lp, lpt1)
- You might have to check off LPR Byte Counting
- Just choose your printer drivers and you should be able to figure it out from there
