I have a MacBookPro with OSX 10.6.8 and a Toshiba laptop with Windows 7 to which is connected by USB a Canon MP250 printer. I have been able to network the two computers, meaning I am able to create a file on the Mac and save it on the Toshiba and vice-versa. But I am unable to print a document from the Mac on the Canon printer which is connected to the Windows laptop. I think I correctly followed instructions here and at http://macosx.com/forums/howto-faqs/...d-printer.html
. The Canon printer does appear on the Mac in the list at System Prefs>Print & Fax. There, at Options & Supplies>Location, it reads smb://TLC1@(the Toshiba's IP is here)/CanonMP250Toshiba. At >Driver, I clicked on the down arrow, then "Select printer software …", then "Canon MP250 series". TLC1 is my username on the Toshiba. It is not clear what username should be in the address at Options & Supplies>Location. I have tried my MBP username and my Toshiba username and the name of the Toshiba itself, and all render the same error, which is, in TextEdit, if I click on File>Print, select that printer, it says "Printer Ready", but when I click on print, I get "Connection failed: NT_STATUS_CONNECTION_REFUSED". Norton Internet Security is running on the Toshiba, but when attempting to print, I have turned off "Smart Firewall". Any help will be GREATLY appreciated! Thanks.
