Networking :: Vista Printer Will Not Print From Network

I'm using Slackware64 13.0 on a laptop. I've set up the network printer which lives on a Windows Vista machine (not my choice) in the family room. I am able to send print jobs to the printer. That part works fine, but the printer does not print. It simply stacks up print jobs with "error - printing" in the status of the first print job.I think I understand what's happening. I'm sending the print jobs to the print server as "Guest" and I have no guest account activated on the vista machine. I'm sitting here racking my brain (ie googling my goddamn fingers into stumps) trying to figure out how to send the jobs to the print server as indubitableness.

For the goddamn life of me I can't figure out what I need to do to send these print jobs as a specific user. I've tried adding "valid users = indubitableness" to smb.conf and I've tried using the -U flag when running lpadmin to add the printer to my system in the first place.The configuration wizard for windows doesn't appear to have any options to enable guest access or to add a specific remote location and/or user to the allow list.I'm at a loss and I'm losing my goddamn mind.
