Error when printing in Windows using a PIN, Face ID, or fingerprint (Windows Hello)

Atualizado/Updated: 2026-05-15

Target Audience: Iscte Employees

Probable Cause:

If you are using Windows Hello (PIN, facial recognition, or fingerprint) and an error occurs when printing, this behavior is usually associated with a Windows authentication issue.

There is a known limitation where Windows Hello may not correctly provide the credentials required for printing, causing failures when sending the job to the printer.

Answer/Solution:

Follow the procedure described in Printing Error – Windows Hello

If the Problem Persists:

If you are still unable to print, please contact IT Support and provide the following information:

- Device used (laptop, desktop)
- Printer name (iscte on printers.iul.intra)
- Location and type of device (printer or multifunction device)
- Authentication method (PIN, face, fingerprint)
  Description of the error observed
- Screenshot of the error message displayed (if available)

The job was submitted but isn’t printing. What happened?

PT

Target Audience: Iscte Employees

Probable Cause:

If you sent a print job but it is not printed automatically, this is due to the normal operation of Iscte’s printing system, which is based on follow-me printing.

In this system, print jobs are not printed immediately after being sent—they remain on hold until released by the user.

Answer/Solution:

To try to fix the problem, follow the steps below.

Go to a printer or multifunction device
- - You can use any printer or multifunction device on campus
  - Submitted jobs are not assigned to a specific printer
Log in to the device
- - Swipe your Iscte card on the reader
  - Wait for authentication
Select the job
- - On the MFP screen:
    - Check the list of pending jobs
    - Select the document(s) you want to print
Confirm printing
- - After selecting:
    - Confirm printing on the control panel
    - The document will then be printed immediately
If you cannot find the job on the printer
- - Verify that:
    - The submission was completed successfully
    - You selected the correct printer when sending
  - Wait a few seconds and refresh the list
  - Check to see if the job is stuck in the computer’s queue
Try resending the document
Try another printer/multifunction device

If the Problem Persists:

If the job does not appear or does not print, please contact IT Support and provide the following information:

- Printer name (iscte on printers.iul.intra)
- Location and type of device (printer or multifunction device)
- Description of the error observed

I can’t find the printer on my computer. What should I do?

Atualizado/Updated: 2026-05-15

PT

Target Audience: Iscte Employees

Probable Cause:

If you cannot find the Iscte printer on your computer, the problem is usually related to the network connection, installation, or authentication.

Common scenarios:

- You are off campus without an active VPN
- The installation was interrupted or incomplete
- Incorrect credentials were used
- The printer was added but did not become active

Answer/Solution:

To try to resolve the issue, follow the steps below.

Check your network connection
- - Confirm that you are connected to the Iscte network:
    - On campus: eduroam Wi-Fi or wired connection
    - Off campus: connection via VPN
  - Without access to the internal network, you will not be able to send jobs to print.
Confirm printer installation
- - If the printer on printers.iul.intra does not appear in the list:
    - It may not be installed or may be misconfigured
  - In that case
    - Reinstall the printer
  - Incorrect drivers may prevent printing or cause errors.
Use the correct credentials
- - During installation, you must authenticate using the format:
    - IUL\username
  - If you use incorrect credentials:
    - Installation may fail
    - The printer may not appear in the system
Use another computer to troubleshoot the problem

If the Problem Persists:

If you are unable to resolve the issue, please contact IT Support and provide the following information:

- Operating system (Windows/Mac/Linux)
- Connection type (on-campus or VPN)
- Steps you have already taken

What is the “follow-me printing” system?

Atualizado/Updated: 2026-05-15

PT

Target Audience: Iscte Employees

Answer/Solution:

Follow-me printing is the printing system used at Iscte that allows you to send documents to a centralized print queue instead of a specific printer.

Submitted print jobs are placed on hold and are only printed when the user logs in to a printer or multifunction device on campus using their Iscte card.

When printing, select the iscte on printers.iul.intra.
The job is stored in the system for a limited time.
- - It is associated with the user who sent it.
  - It is not visible to other users.
Go to any available printer or multifunction device on campus.
Authenticate with your Iscte card.
Select the document(s) and confirm printing.

Advantages of the System:

- Security: Prevents documents from being left exposed in trays
- Flexibility: You can print on any printer on campus
- Waste reduction: You only print when necessary, and if not retrieved, documents can be automatically deleted after a certain period
- Mobility: Does not depend on a specific location

If You Encounter Difficulties:

You should contact IT Support, providing the following information:

- Printer name (iscte on printers.iul.intra)
- Location and type of equipment (printer or multifunction device)
- Document name (if possible)
- Description of the error observed
- Screenshot of the error message (if available)
