Hi Arek,
I finally have time to do more testing and I am getting the same results as you.
POC has no color option and P2P ignores it when I set it also.....
But this may be because the IT department configures our printers and we install the drivers to the network share.... I don't have admin rights to make any changes to the printer settings so P2P changes will be ignored.
All I can suggest now is you have 2 printers defined on their PC's, one for Color and one for black and white and then select the appropriate one at runtime. Or save the report with the printer COL or BW, you can do that by opening the report in CR Designer and click the Print button. Make the changes and click Apply and then cancel. Then save the report, this saves the printer set up in the RPT file.

PS - I'll ask DEV if we can add a color property to POC and ask if P2P color property should work.
