Changing the Print Processor

Hi. I have problems with my printing jobs. There are related at https://www.techrepublic.com.com/5208-6230-0.html?forumID=101&threadID=253517&messageID=2421650
I’m thinking about to change the print processor who actually is HPPRN05 and put in a WinPrint. Do I have to save any system information before? is there any danger to change the printer processor of a TCP/IP network printer connected with another one to the same HPJetDirect?. Thanks
