How can I make Safari print clearly the “gray” (lighter) text in some webpages, including Apple’s. I often need to print that information, particularly when I need to request purchasing software/hardware and provide a print out at work.
Allow me to take you to a place you’ve likely never visited. Find a web page you’d like to print and press Command-P. In the resulting sheet choose ColorSync from the pop-up menu that reads Copies & Pages. Two pop-up menus will appear—Color Conversion and Quartz Filer. Choose Add Filter from the Quartz Filter pop-up menu.
ColorSync Utility will launch and display a preview of the page you intend to print. From the Filter pop-up menu at the bottom of the window choose Lightness Decrease and notice that the grays on the page get darker (as does everything else on the page). Take a look at some of the other filters and see if they make the text darker (Black & White, for example, though it may cause the gray text to completely disappear).
If none of the filters please you, you can make one of your own. Click the area where you see the red, green, and blue ovals in the upper-left corner of the window to produce the Filters window. Click the Plus (+) button in the bottom-left corner of the Filters window to create a new filter. Give the filter a name such as Darker Gray.
Click the triangle symbol that appears next to the profile and choose Add Color Management Component -> Intermediate Transform. In the Intermediate Transform entry that appears choose Brightness from the Profile pop-up menu, Gray Data from the All Data pop-up menu, and Text from the All Objects pop-up menu. Adjust the three sliders that appear and see the effect they have on the page preview. When you find something you like close the Filters window.
When you return to the Print sheet to print your page, choose Color Sync from the Copies & Pages pop-up menu and then choose the filter you created from the Quartz Filter pop-up menu.
