Powershell: Add registry value based on current user

Question

I would like to automate a network printer install that uses secure print. I can push the actual install out through group policy, but I need script that will assign each persons unique ID number to the printer settings. 
Get current user name
Check that user name against a spreadsheet or .txt file list. This list would have hundreds of unique user names in column A, and a unique ID number in column B.
Example:
Column A (username)               Column B (ID Number)
User 1 
      123456
User 2
      789101
Write the ID number in column B to a specific registry value.
Any idea's??

You would use New-ItemProperty or Set-ItemProperty to write a registry value. New-* will allow you to set the value type (you can use -Force if it already exists). Here's an example of using Set-*:
# Set a value named 'ValueName' in the key stored in $RegPath to 'ValueGoesHere'
Set-ItemProperty -Path $RegPath -Name ValueName -Value ValueGoesHere
If you need to get a value, you can use Get-ItemProperty:
# Get all values for the Windows Update service's key:
Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\services\wuauserv
# Just get the start value (returned as an object with start and extra PS properties):
Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\services\wuauserv -Name Start
# Just get the start value (just the value):
Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\services\wuauserv | select -exp Start
(Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\services\wuauserv).Start
