Sometimes, Citrix modifies users' default printer, They may have a printer set as the default and certain users may change it to the default printer on the servers. Previous steps: Logically, we have had to configure the Citrix policies in which it is indicated that the default printer is the client and not the server. Have the client printer drivers installed on the Citrix server in case the drivers provided by the user are not compatible.

We have to take into account that the user with the problem must be logged into a Citrix server, we will log in to that Citrix server as an Administrator and we will perform the following tasks:

First to guess the user's SID, we must download a tool called "PsGetSid" that we can download for free on Microsoft's website: https://docs.microsoft.com/en-us/sysinternals/downloads/psgetsid

Unzip the tool, for example in M:pstools and access from an MSDOS console to the directory. Simply by running the: “psgetsid DOMAINuser“, We will know what SID the user has.

We must open the registry and enter the:
HKEY_USERS > User SID > Printers; there will be a registry key that we must delete called "DeviceOld".

In: HKEY_USERS > User SID > Software > Microsoft > Windows NT > CurrentVersion > Devices. We have the list of printers to which the user has access. We must copy the name of the key followed by a comma and its data. For example: porte2epsonaccess2,winspool,Ne04:

And we're going to : HKEY_USERS > User SID > Software > Microsoft > Windows NT > CurrentVersion > Windows and we modify the value of "Device". So that the default printer is not the one that comes there, in my case a PDFCreator,Winspool,Ne00:

We paste the new printer into the "Device" value, The data we copied before, in this example we would put Device with porte2epsonacceso2,winspool,Ne04:

We close registration, after the user's session and when the changes are logged in again, they will take effect.
