Pdf crack issue

[simplyslow]

I pull down a pdf file from a public site that allows one to view the pdf but not print without a paid password. I save the file and run pdftohashcat.py and get: $pdf$2*3*128*-8*1*16*9ce0<redacted>a204. I run oclhashcat and it cracks instantly with this output:$pdf$2*3*128*-8*1*16*9ce0<redacted>aa204:

Which I read as, "blank, no entry"

I attempt to enter this when the password is requested when I attempt to print the file but it is rejected. What am I not getting? Thanks.
