Need Assistance Using the Printing All PDF FIles Script

So i am building my first powershell script and ran into a hurdle.  In short, when i print the pdf files in the script below, it is printing out two files that i opened in the past instead of the files that I specify in the script.  

This is the script i borrowed (which is excellent to find.. hopefully just needs a tweak :) )

and here is my script.  I want to log the files in a location, print them, and then move them to another location.  

#Set Path

$path='c:\_print'

# Set date variables

$year=get-date -format yyyy

$month=get-date -format MM

$day=get-date -format dd

$date=get-date -Format MM-d-yyyy

$monthDay=get-date -format MM-dd

# Test if folder for the year exists and create it if it doesnt.

if(test-path $path\$year) {"there"} else {New-Item $path\$year\ -type directory}

#create the folder for the day

new-item $path\$year\$monthday\ -type directory 

#write the files in the folder to a log file in the folder

Get-ChildItem $path\*.pdf | out-file $path\$year\$monthday\log.txt

# print the files  

$printing=start-job{Get-ChildItem $path -filter *.pdf | Foreach-Object { Start-Process -filePath $_.FullName –Verb Print }}

wait-job $printing

receive-job $printing

#move the pdf's to a dated directory

move-item $path\*.pdf $path\$year\$monthday\
