Fill a Used Print Cartridge with Invisible Ink

9:30AM Kevin Purdy | If you’ve got a spare printer ink cartridge and a document you only want one person to see—or just some free time and a cloak-and-dagger kick—one helpful Metacafe post has a project for you. The tutorial requires a utility knife, some invisible ink pens and a syringe, and an empty ink cartridge, with black seeming to be an easier solution that the yellow-only solution the creator recommends. It’s a fun way to cover up sensitive documents, and a guaranteed friend impresser as well. How Make Invisible Printer Ink [Metacafe via Instructables] More »

Print Your Own Ruled Paper

Recycle Your Old Computer Into a Print Server

1:00AM Wendy Boswell | Save some system resources and share multiple printers between more than one machine by recycling that old “junk” system sitting in your garage into a dedicated print server. eHow has a step by step tutorial that takes you through exactly what you need to do to accomplish this; the process is a bit lengthy, but well worth it if you share printer resources. FYI, this also frees up counter space since your printer can be wherever you want it with this setup—and it will work even more efficiently if you network your printers.

Change the Default Message on HP Printers

8:00PM Gina Trapani | Flummox your coworkers with an “Insert Coin” message on the office printer using the HP Printer Job Language (HPPJL) command set. The Hackszine blog describes how to customise the Ready prompt on HP printers’ LED display with a few simple commands: I haven’t been able to test yet (no HP printer here), but if I’m reading the code right, you can actually do this right from the command line using telnet. Just telnet to port 9100 and type in the following: \e%-12345X\@PJL JOB \@PJL RDYMSG DISPLAY="MESSAGE HERE" \@PJL EOJ \e%-12345X Sadly, I don’t have an HP printer here to test this out either, but I’d love to see someone pull this off. If you do, let us know how it goes in the comments. (Oh yeah, and here’s how to undo it when the boss hunts you down.) Change the message on HP printers [Hackszine] More »
