. What software version of Abobe Acrobat Reader should be used for an HP PhotoSmart Plus printer? I currently have Adobe version 9.3 installed. I receive pop-up notices to install new Adobe Acrobat Reader software upgrades. I have installed the software upgrades and then my HP PhotoSmart Plus printer was unoperational. I deleted the Adobe software upgrades and my HP PhotoSmart Plus printer began to operate. I contacted HP technical support and was told there is no compatibility issues between Adobe Acrobat Reader and HP All-in-One Products. It might be a problem with the specific Adobe software upgrades. HP requested that I contact Adobe support for problem resolution. Has this problem ever happened to you? Any problem resolutions would be appreciated.
