How to send a PrintSystemJobInfo with printer required credentials?

Hello all, im in the process of finalizing a C# project for my school, this is connected to a printer by network which then (the printer itself) will ask for Login ID and Login Password in a popup window, the login details are not windows accounts, they are probably stored inside the printer itself, my main issue with this is that the window get spammed everytime i send a jobinfo to it, which is very annoying and unprofessional, is there a way for me to send the login and password info and avoiding that login credential request window?

Excuse me if its something very obvious, ive tried my way around the internet, granted i didnt search everyday but so far i havent found anything even close to my question xD
Any information will do, if its possible, if its not and how can i do it if its possible.
Thanks in advance!

No replies yet, hmm is this thing simply not possible? or is it too hard to achieve? if so could someone tell me if it is? it would mean alot to me any information about these printer credentials, im using a printqueue and a printserver to print a xps file, all i know is how can or if i can avoid the printer username and password request by providing them automatically.

Thanks again guys.
