Q: unable to connect with network printer

maybe it is best I clarify the setup:

 

my ISP is my college. they provide me with a static external IP, which I will not disclose. I connect directly to our network, without any kind of router, so the settings are all made right on my Mac, including the subnetmask, which is set to 255.255.254.0. the printer also has a fixed external IP. furthermore, two DNS servers are specified in my IP settings.

 

even though networking etc. is not my strong suite, I do not see how this would affect me beeing able to print? Isn't the idea of IPP that I can (in theory) print on a printer in japan?

 

thanks for all the input

I was not suggesting you disclose your public IP. But are you sure you and everyone else going to that school has a public IP? That would be very risky for all students and faculty to have public IPs and the networking behind it would also be very complicated.

Whether you use or don't use a router does not mean your school doesn't for access to the internet.

Yes this has nothing to do with your specific problem. Actualy it is not your problem. Most everyone that uses a Mac and a networked printer has this problem. As stated before Apple says you might have to connect the printer to a USB port, WHAT!!!

Sorry I haven't been able to help.

Good Luck

Oh, that is different.

In that case, those addresses will be on the same subnet. I stand corrected.

decimal xxx.yyy.140.zzz becomes binary:

140: xxxxxxxx.yyyyyyyy.10001100.dddddddd

141: xxxxxxxx.yyyyyyyy.10001101.dddddddd

msk: 11111111.11111111.11111110.00000000

Rule: a One in the subnet mask requires the bits in the Addresses be the same, a Zero means differences do not matter.

Those WOULD be on the same subnet., as long as xxx and yyy fields are the same for each of the two IP addresses. False alarm, sorry.
