You say the first account works. That first account likely has a NAME. Let's call it the first user. On the server that serves up the printer there should be an account for "first" to give them permission to use the printer.
Now you add a new user to the machine. Let's call that the "second" user. Did you get an account setup fro "second" on the server?
Many forget this basic item.
I have XP Media Center Edition.
I added another user, but the new user does not have access to the printers that are defined to the main account. No printers are defined under the new user account.
I hesitate to define the printer under the new account, because then *two* printers would be defined (even though they are *one* physical printer), and there could be lockouts from conflicts. I assume that network printer sharing is not the appropriate appoach for users on the same computer.
What to you suggest?
