How can I print encrypted PDFs from my iPhone?

Hi all,

Long story short, I got a staff member who is trying to print a PDF from his iPhone to the building printer. If he tries to print it or saves it and tries to print it, he gets this error and it says "Password is either missing or incorrect".

However if he sends me the file, I can open and print it from a web browser or save it and print it from my machine to the same printer. Both using either MacBook or Windows.

Thoughts?

Thanks,

Your post’s title suggests the password is associated with the PDF file. However, nothing in your post’s body confirms that.

Ignoring your post’s title, one scenario that accounts for the behavior described in your post’s body would be the staff member not properly using the Wi-Fi network associated with the printer and/or storage device, while you are.

The issue is encrypted pdf files. He uses AirPrint. I looked deeper into the details of the file. It is password protected, however the protection is from modifying it. Opening and printing are allowed. I'm just trying to figure out if maybe it's an issue with AirPrint and encrypted PDF files. I have checked so many resources online, still stumped.

The only time I had to enter a security code, is when he shared the document to me via my email. After entering the code I opened and printed the document just fine. From his phone he is opening the document fine, it's just the printing part.

Its issues with all PDF files I believe. he just recently started printing from his phone after I set his phone up to wifi in the building. I requested to have the sender send a new copy of the PDF to make sure it wasn't some type of corruption. As far as I know AirPrint is the only protocol to send a print job from an iPhone?

Looks like my latest post never saved. The staff member is having issue with all PDFs I believe. He just started printing from his phone to the building printer as I just recently connected it to wifi. Also is AirPrint the only protocol to print from on iPhone?

Though all the staff devices are to be connected to the staff network, I did check to verify that his phone is connected to the staff network. The printer itself is connected by ethernet.

Can the staff member print other items, just not this one PDF file?

What method is used to print? Is it AirPrint? Presumably you and the staff member use the same method.
