Sharing printers

Hi, I have just installed exe linux with the Trinity desktop (exe is basically debian 7) and I am trying to share a local USB printer (HP Deskjet 1000). I checked the "Shared" box in CUPS but it still can't be found by other networked computers. I installed system-config-printer and it opened showing that the printer is shared. Any ideas? Also, I was going to include the version of Trinity in the first line, but I don't know how to find that. I usually open synaptic to find what versions are installed, but it's not listed under the name Trinity. Thanks, Don
