I have a Desktop computer (main comp) connected to a router. This is a DHCP server. I also have a laptop with built-in wireless NIC card.

I installed my HP Officejet 6300 to my main computer but I want to share it so my laptop can print. *i have no problem going out to the internet*
*also it's on the same workgroup, not sure if it has to do anything with sharing*

Problems:

can't ping my main computer
can't view printer share on a network

my main computer's ip address is 192.168.x.x
with a 24 bit subnet mask

so for my laptop i put in as 192.168.x.x
but still wasn't able to ping my main comp

I checked the windows firewall for allowing echo request but still nothing

What am i doing wrong? I've tried everything I know. If anyone has any solution to this problem, please post.

Thank you
