Have 2 pcs of E-studio 550. One of them prints PDF quickly and another is very slow. GL-1020 Configuration Page shows different print driver versions on them. Print Emulation on quick one is <Postscript Level 3> and on slow one there's <Auto>. How can I make slow one to be quick without cloning HDD of quick one and swapping HDDs ? I have a GL-1020 recovery CD but when I recovered I saw that it's the slow PCL version. How to upgrade to Postscript version ? Thanks..
