ricoh 3110dn print modes and substrate mode

[paul 44]

Hi folks,

Quickie, is it beneficial to keep my ricoh on photo quality (as it is in powerdriver settings) or is there a noticeable difference if the print quality is reduced to say graphics mode via the powerdriver?

Also, the substrate is set to unisub products on the powerdriver software, is there a noticeable difference if this setting is changed to ceramic/glass when printing mugs, I have never changed this setting so it has always been on unisub products setting when i've printed mugs, not ceramics/glass.

Thanks
