I am having a KXP-1121 Dox Matrix printer on my network. It is shared with everyone. Now I am having a problem with fixing the paper size. Each time when I try to print it change the size to something else. I want here to set a custom paper size and lock the settings. I tried doing that manually but it did not worked. It looks like the printer is taking different settings from each pc due to which I am facing the problem. Anything I can do here.
