PowerShell script for exporting Print Server info to Oracle

The example below covers how a PowerShell script can connect to a Windows Print Server, how it can query printers information, and how it can connect to an Oracle database to perform a query.

# Start configuring parameters
Param (
	[string]$Printservers = "printserver1",
	[string]$OracleServer = "orcl",
	[string]$OracleUser = "scott",
	[string]$OraclePassword = "tiger"
	[string]$sql = "insert into printer_list (print_server, printer_name, printer_location, printer_comment, printer_ip, printer_driver_name, printer_driver_version, printer_driver, entry_dt) values(:print_server, :printer_name, :printer_location, :printer_comment, :printer_ip, :printer_driver_name, :printer_driver_version, :printer_driver, sysdate) "
)
# End configuring parameters

ForEach ($Printserver in $Printservers) { # Start looping through each print server
	$Printers = Get-WmiObject Win32_Printer -ComputerName $Printserver

	ForEach ($Printer in $Printers) { # Start looping through each printer
