In the Print window, the option to "Print Selection Only" is not working all of a sudden.
Starting yesterday, I can no longer print selected text that I have highlighted from various websites. This issue is present with both my browsers (Firefox and Safari) and both my printers. It does not matter what webpage I'm on, the problem is affecting all webpages. It's as though the computer is suddenly unable to recognize that there is highlighted text on the webpage, so the option to print the selected text only is not available no matter which browser I use or which printer I use. (The option to Print Selection Only is grayed out in Firefox. In Safari, the print window thumbnails show the entire document is about to be printed.)
Note: When printing selected text from Word documents, I am able to print just the highlighted text, so the issue is limited to printing selected text from websites only.
In trying to resolve the matter I ran Disk Utility from my normal login and from safe boot, cleared the system and user caches, reset the PRAM and the SMC, but the issue remained. So I trashed the printer preference in ~/Library/Preferences/com.apple.print.PrintingPrefs.plist, restarted the computer, turned off/on both my printers, but I am still unable to print just the selected text. I do not understand what has caused this issue to trigger all of a sudden. Any assistance or suggestions you can provide me is very appreciated. Thank you.
