Hi. I hope i posted in the right place. I installed the printer Officejet pro 7520 (then tryed also with a officejet 7510) on a PC with Windows XP Pro 32bit. Downloaded the originel driver from HP. It will install without problems, but the printer doesn't print. Even the test page. When i send a file the print queue show the file for just a few seconds and the disappear like the file is succesfully delivered. But the printer doesnt react. Then i controlled in the print properties and i discovered that was selected the print processor of MS_XPS (???). I changed it in "winprint -> RAW", and now, every file i send (also the test page) come out a lot of paper and every page has just a line of text. - Tryed the configuration it in USB and wireless - Tryed with hp doctor to reinstall all the software and every possible instruction. - Removed every old HP software (like the one of the old HP printer that was perfectly working until his last day officejet 7500) - Tryed sfc /scannow Every time i reinstall both printers, is selected the wrong print processor by default and changing it wont help I wanted to try the method five to do a clean full uninstall displayed in this page: [URL]https://support.hp.com/us-en/document/c01704046[/URL] but the file "gr.uninst.exe" is no longer available. The printer and PC are from a customer of mine and he need windows xp to run an old software, so he can't change the PC. There is someone that can help me?? Thankyou
