Powershell-Automated printing to pdf of a webpage

I am trying to automate the printing of a webpage using Powershell. Everything is running perfectly except for the naming of the pdf. I am trying to make it save the file as the current date, but for some reason it won't. If someone could help me, it will help my business a lot.

P.S. I would like the date to be in this format Month, Day, Year; and if the date or month are single digits, put a zero in front of them

Here is my code

##############################################################################

# provide the location where the PDF file will be created     #
$OUTPUT_FOLDER="C:\Users\Programming\Desktop\pdf"
 

#used to press enter to save file

$wshell = New-Object -ComObject wscript.shell;
$wshell.AppActivate('splwow64')
Sleep 1

#making auto save date
$b = Get-Date
$ye = $b.year
$mo = $b.month
$da = $b.day
$a = "$mo $da $ye"
$c = Get-Date -format MM-dd-yyyy
 
write-host ($a)
write-host ($c)

   
# a name for the PDF file without the extension             
# without a name the file name is the current timestamp    
$OUTPUT_FILENAME= $c
 # comment following line to add a timestamp to each file gets created
if($OUTPUT_FILENAME.length -eq 0) {$OUTPUT_FILENAME=(Get-Date).tostring()}

#website url
$website=" "
