Hello, printing the PDF available at this link will result in various black areas, but only in color mode (see picture).
Printing in black and white has no issues. I printed from iPadOS 14, iOS 14, macOS 10.15.
Converting to TIFF the PDF and then printing the TIFF has no troubles.
Printing original PDF to PDF via macOS Preview, then printing the such obtained PDF, will have black areas.
Printer has last firmware available, just checked. Anyone can tell me what's wrong? Thanks in advance.
