Springy Dock Tricks

If you drag a file and hover over Dock icons, various useful things happen which are similar to Finder springing. If it's a window, the window un-minimizes from the Dock. If it's a stack, the corresponding folder in the Finder opens. If it's the Finder, it brings the Finder to the foreground and opens a window if one doesn't exist already. But the coolest (and most hidden) springing trick is if you hover over an application and press the Space bar, the application comes to the foreground. This is great for things like grabbing a file from somewhere to drop into a Mail composition window that's otherwise hidden. Grab the file you want, hover over the Mail icon, press the Space bar, and Mail comes to the front for you to drop the file into the compose window. Be sure that Spring-Loaded Folders and Windows is enabled in the Finder Preferences window.

Double-sided Printing

Send Article to a Friend

Double-sided Printing -- Several people wrote to warn against printing on the back of already-printed sheets of paper, as recommended in TidBITS #175. Joe Gurman relayed information from a repair person who claimed that some high-speed printers (the one in question was an older Ricoh engine used in the Talaris 1590 printstation) were more likely to jam when using reused paper because of changes in the paper when it was exposed to the high heat in the laser engine the first time through.

Another reader claimed that some laser printers contaminate the paper with small quantities of fuser oil, and reusing printed paper can cause this contaminant to migrate to places it doesn't belong, such as the rollers that grab the paper. If anyone knows for sure about this issue (in other words, if you're a printer repair person or printer engineer, not just relaying a possible computer legend) please let us know and we'll try to settle this issue once and for all. In the meantime, if you wish to play it safe, check with your printer manufacturer.
