I am unable to give prints with USB it is asking to enable POST SCRIPT.
Error: Job Deleted
MSG:The job was not printed because the postscript option is not enable. contact your system administrator to enable postscript on this devise
You can't print pdf from USB without the Postscript kit installed in the device (purchasable option)
So if this is not listed as installed you can't do pdf.
And in that case I think your only option is jpg or Tiff files
Tech installs it, it isn't free and it isn't just a software, it requires hardware installation, you get it through your sales rep
