Guys i need a hand, I saw a product online a while back but i can't seem to find it.It's a device that can replace a computer in a cartridge print test process.You can simply take the usb cable from the computer and plug in into this device, press a button and presto it sends a test page to the printer.Sometimes my computer slows down operation by having to spool documents and with this device you can just plug and print.Has anyone seen this before?:/
