Powershell if else condition ignore warning keep to continue - powershell

Question

I would like to design a condition which is if the tcp connection result is return "true", will proceed install action and go next function. Otherwise, it will return a warning message, stop to proceed and pass to next function. I don't know how to implement keep to proceed next function if occurs any warning on current function.
Is there anybody can help to fix the issue?
Many Thanks.
function A(){
$printerIPAddress = "192.168.1.100"
$sharedPrinter = "\\SERVERNAME\A"
$checkPrinterExists = Get-Printer -Name $sharedPrinter -ErrorAction SilentlyContinue
if ((Test-NetConnection -ComputerName $printerIPAddress -WarningAction SilentlyContinue).PingSucceeded){
Write-Host "Succeed to connect - $printerIPAddress" -ForegroundColor Black -BackgroundColor Gray
Start-Sleep(2)
}
else {
Write-Warning "Failure to connect - $printerIPAddress"
}
if (-not $checkPrinterExists){
Write-Host "Installing a printer..."
Add-Printer -ConnectionName $sharedPrinter
Write-Host "Succeed to install - A Printer" -ForegroundColor Black -BackgroundColor Gray
}
else{
Write-Warning "Failure to install - A Printer already exist"
}
}
function B(){
$printerIPAddress = "192.168.1.101"
$sharedPrinter = "\\SERVERNAME\B"
$checkPrinterExists = Get-Printer -Name $sharedPrinter -ErrorAction SilentlyContinue
if ((Test-NetConnection -ComputerName $printerIPAddress -WarningAction SilentlyContinue).PingSucceeded){
Write-Host "Succeed to connect - $printerIPAddress" -ForegroundColor Black -BackgroundColor Gray
Start-Sleep(2)
}
else {
Write-Warning "Failure to connect - $printerIPAddress"
}
if (-not $checkPrinterExists){
Write-Host "Installing a printer..."
Add-Printer -ConnectionName $sharedPrinter
Write-Host "Succeed to install - B Printer" -ForegroundColor Black -BackgroundColor Gray

else{

Write-Host "Running...Please wait..."

I've attempted to simplify your code and also inherently handled the "stop to proceed if Test-NetConnection fails" scenario.
As your main objective is to install the printer, the function will error out if the parameter $sharedPrinter fails the defined ValidateScript criteria.
Function Install-Printer {
[CmdletBinding()]
Param(
[parameter(Mandatory=$true)]
[ValidateScript({$_ -match [IPAddress]$_ })]
[string]
$printerIPAddress,
[parameter(Mandatory=$true)]
[ValidateScript({(Test-Path $_) -and ($Printer = Get-Printer -Name $_)})]
[string]
$sharedPrinter
)
if ((Test-NetConnection -ComputerName $printerIPAddress -WarningAction SilentlyContinue).PingSucceeded) {
Write-Host "Succeed to connect - $printerIPAddress" -ForegroundColor Black -BackgroundColor Gray
Write-Host "Installing a printer..."
Add-Printer -ConnectionName $sharedPrinter
if($?){ # if previous command succeeded
Write-Host "Succeed to install - $($Printer.Name) Printer" -ForegroundColor Black -BackgroundColor Gray
}
else {
Write-Warning "Failure to install - $($Printer.Name) Printer already exist"
}
}
else {
Write-Error "Failure to connect - $printerIPAddress"
}
}
Write-Host "Running...Please wait..."
# Install Printer A
Install-Printer -printerIPAddress "192.168.1.100" -sharedPrinter "\\SERVERNAME\A"
# Install Printer B
Install-Printer -printerIPAddress "192.168.1.101" -sharedPrinter "\\SERVERNAME\B"
