Is it easy to smear? When will HP have a >non-soluble ink? I tried out the DeskWriter at the dealer, and one of the big things on my mind was the soluability of the ink. The salesperson claimed that the DW was using standard laserprinter paper, although I'm not sure I trust him (he also claimed that the CS Palacio font [Palatino] wasn't installed, and that the magnificent 72-point text I was seeing was a scaled screen font.... :-)) First, a note on the way the DW prints: The printout comes out sliding along on top of a pair of rails above the output bin. When the page is finished printing, the rails move aside and the page drops onto the stack in the bin. I assume that this is in order for the ink on the page below to dry before another sheet is dropped on top. With this assumption in mind, I tried the _second-from top_ sheet on the output stack with a dry finger. No problem. Nothing. Then I dampened a finger and ran it over text. Very slight smear. Then, a dampened finger over a solid rectangle. Larger smear (very noticeable). Then a _really_ dampened finger and lots of pressure on text. BIG smear. Okay, so I took the printouts home. On the subway, that took about an hour. Then, I tried it all again. This time, for text, it took a significant amount of both moisture and pressure to induce text to smear, and much more than before to make the rectangle smear. Read: it dries more over time, and becomes difficult to smear. NOW, the fix: There are two, actually. You can spray each sheet with a fixative (from an art-supply store). I haven't tried this, since I don't own one of the printers. It would be worth a shot, though... Second: In MacWeek's review of the DW, they say that HP is working on a non-soluable ink for the printer, though they don't give any estimated dates. The conjecture from folks that I've talked to is that it should be a _real_ easy conversion, since both the inkwell _and_ the printhead are replaced with each ink cartridge. Therefore, any changes that need to be made to the printhead won't be something you have to take the printer to the dealer for. It will be automatic when you change ink. :-) --Mike Disclaimer: I hate disclaimers. I think they're a sad statement about our society.
