sorry, but i can see the screenshot now... it was not visble at first...
thats indeed strange, but since its an fiery driver and not a xerox driver, i think you will have better chance of support on the fiery/efi forums located here : http://fieryforums.efi.com/
in the printing prefereces, in the advanced tab, there is a setting for : download as softfont, that way yoo send the font you are using to the machine instead of using machine fonts , have you tried that ?
Having a problem with Xerox print drivers on a customers machine, this issue affects a number of different Xerox printers, but only on the one machine.
Fonts in the print options screen are changed to Fixedsys, this increases the size required and pushes some of the controls off the window.
Anyone got any suggestions?
