But ... same comment. If either Preview or Chrome are opening a PDF, modifying it, then saving the modified version without a customer acceptance, then that company is violating all digital protocol. You never save a document without a customer's current acceptance or (as in the case of MS Officer and similar products) saving backup's, but not overwriting the original. And, if an app modifies a file in order to make a working copy of it (to print, to display, to attach to an email) as is the digital industry standard, that company would find itself in deep trouble. I can't think of a product I have worked with that opens the original and modifies it in place, so that a single computer glitch would destroy the original file. When, copying, moving or editing a file, SOP is make a working copy, use it, while (usually) the original is locked, then save it as the user desires (in a new location, with a new name, or overwriting the original). Both Apple Preview and Chrome have been in the industry a long time; and I have a hard time believing either of them would violate standard safety protocols. This sounds like some of those fear-mongring news items that requires a Snopes investigation before one becomes overcome with anxiety. What can happen, however, is if the printing is done by the product interface, then any special process to affect outcome (such as printing a line, then doubling back to print over it) would probably be lost; and the user would not get the effect they wanted. However, in this case, where the user accesses the printer interface to "throw switches" (double-space or not; header page or not), then returns to the Acrobat interface to do the actual printer, the product should be printed as expected. But, even if you don't believe in the above scenario, I am sure you can agree with the point I and numerous others are making: include those switch-throwing options in the Adobe/Acrobat interface so we don't have to be filled with doubt or anxiety by leaving the product and then returning to it. That's what one would expect from a once established powerhouse such as Acrobat (or any other Adobe product). Yes?
