You might experience that a print-job is getting "Error", but documents afterwards can still be printed.
Some documents will be sent directly to "Error", and the reason for this is really hard to find, because there is so many problems that can occur.
Normally sensitive documents can trigger the error status because they are encrypted. Specially of you try to send directly from your email.
The best solution, is to download the document onto a PC, and from there try to print from Adobe Reader.
