Printer doesn't print hatch in transparency

[Anonymous]

So I have this problem. I have hatched my drawings with solids and have set them up at different transparency. When I print it off from my printer and my boss's printer, they print perfectly alright with transparency. 

But when my client and my co worker printed on their printers, no transparency was printed. Instead it was just black everywhere.  Please help me understand what is going on. 

Attached the picture that shows what's happening.

And... which printer and printer driver are you using?
Which printer and printer driver are they using?
What have you all tried together on the phone/emails before coming here?

Looks to me like they are using a MONOCHROME setting and not a "color" or "grayscale" setting, there is nothing you can control from your office, you need to be over there changing their driver settings most likely.

What if you tried something else like PLOT to a PDF from inside AutoCAD, then from the PDF to the printer that does not work?

In my gut I felt like it was a problem with the printer settings. It prints off okay if they do black and white on their printer settings. But I really want to know if there could be a solution from my end so that I don't have to send out instructions to everyone on how to print.

There are two places they need to look and fix (nope, you can't do it for them from your end in your PDFs):
1) their printer driver must NOT be set to MONOCHROME or B/W printing.
2) Their PDF viewer's print pop-up must NOT be set to MONOCHROME or B/W printing.

Or you could just print to paper and have it delivered: go old-school, it never fails.

Hmmm, the red box tells me, that "monochrome" wasn't used.

To print with transparancy, this checkbox has to be marked.

...still nothing you can do, if THEY print it.

EDIT:

Or you could change the hatches to non-transparent and the colour to the grey, that they supposed to have on paper. Now only the "momochrome"-setting could mess it up.
