      Personally, I think the best source of photo printing is at a photo lab. If a photo is worth printing out, do it properly, so it gets printed with inks that wont fade with time. And certainly in my case, it's still cheaper. Home photo printers are a costly gimick.
      • While I completely agree with you for mass printing, there are cases where photo printer is so much more convenient that it outweight all the drawbacks (quality and price).

        Not mentionning that modern inks (at least EPSON ones) don't fade with time as much as they used to. They are actually pretty good in that regard.

        But when you're in a rush, doing tests, or just printing the one picture of the day, photo printers are the right tool for the job.

        Just for the record, a lab print isn't ink-based, at least at the shop I go to - they use one of these suckers [cymbolic.com] (maybe not that exact brand/model, but you get the point) to "paint" the image onto genuine light-sensitive color photo paper that's processed the old-fashioned way with chemicals. $1.99 for an 8x10, $2.99 for an 11x14. They look a hell of a lot better than any photo print I've ever seen, including dyesubs, and they last and last. When I do a print for my small photography side business, I do it this way...the client is almost always amazed with the result, and asks me what kind of printer I use, they just have to get one for themselves. I tell them "trade secret" :)

        If you just have to use your printer, I'd suggest Ilford GALERIE Classic [ilford.com] paper; it has an encapsulation system that soaks up the ink and mostly protects it from fading, It's pricey (enough so that there's NO economic advantage over a lab print) and takes a full day to dry out, but it is as close to perfect as you're gonna get from an inkjet. When I do prints for my own consumption, I ususally go this route for the convenience.
      • I agree that you can't beat a decent lab for print price and quality. I am sure I saw something recently on /. that suggested that the price per print you could get from a typical lab was such that there was no economic advantage of printing at home.

          This is certainly true for typical consumer labs. However, if you can find a (reasonably priced!) pro-oriented lab that provides you with an ICC profile for the printer and paper they use, and you have a full colour-managed workflow with a properly profiled monitor, excellent results should be possible. There's a good guide to this approach here:

      When you're out shopping, the higher the resolution, the smaller the dots...

      No, higher resolution does not necessarily mean smaller drops. Smaller drop size means smaller drops.

      The best way to gauge any printer's photo capabilities is looking at sample prints at the store

      Except that these are often highly tweaked images and are sometimes even printed from a demo application that doesn't even use the usual printer driver.

      or on printer company websites.

      Huh? Am I supposed to judge from an image on the website, or should I download a sample and print it out? (It reminds me of a TV ad trying to demonstrate how much better the colours are on their TV...)

      Another important specification for inkjet printers is ink drop size, typically measured in picoliters. The smaller the number, the more ink per square inch can be placed on the paper.

    The HP printers have three things going for them: First, they're cheap. Second, the printhead is on the cartridge, so a clog means a lost cartridge, not a lost printer or making a flush kit to force Windex through your print head. Third, the HP printers still look great in draft/high-speed mode. Some inkjets look like old color dot matrix printers in high-speed mode.

    The big downside is drivers. UGH, HP drivers! They crash at random, require you to be an administrator to run the scanning software, add 20-30 seconds to your login time, and do weird things when other HP software is installed. (For example, installing my HP DVD burner software caused my HP printer driver's launcher to launch an explorer window pointing to the directory with the printer software install every single login. This, on a fresh install with nothing but the HP DVD software installed after XP.)

    On the Mac side, people with Tiger and HP printer-scanner-copiers are -still- waiting for a promised update to enable HP-supported scanning, or are giving up and using ports of open source scanning software.

    The HP PSCs are comparatively painless with Linux and *BSD, but check out some of the other options if you'll be using Windows or Mac OS on the same machine.

      You obviously have never expeienced the hell that is the Epson Status Monitor which must run in order to use a consumer epson photo printer. If anything should go wrong, the system will hang (print system, not the OS). And if you've ever had to reinstall a driver due to a bug...oh, you're in for some fun. You see, the uninstall doesn't actually uninstall everything, and a full removal requires both manual tracking down of all the epson driver bits (search for E_ in the entire system directory), and editing the registry.

      In addition it makes them almost impossible to use with a network print server. Any fault - paper out, ink low, etc - causes the job to hang, and fixing the problem results in the first burst of data getting printed, while the print server stays locked up tight as a drum. To get the system working again generally requires either a reboot or manually killing the entire print spooler service and manually restarting it. Even worse, if you clear the error and do not power down the printserver and the printer, the first burst of information will make it through to the printer, and then the printer will hang. No big deal? Well, since the first few lines of ink get put down, it effectively ruins whatever media you're using. For something on bond it's merely annoying. For an 8x10 glossy print or a printable CD or DVD, you've just thrown away $.25 to $2.00 (or more for a DL DVD) in media. Of course, as a bonus, your required power cycle results in wasting a slug of $$$ ink to the startup cycle.

      Sadly, I stick with Epson because the output is just so damned good, and I really like the CD/DVD printing feature. Sort of like having a beautiful but high maintenance girlfriend who's a tiger in the sack - you learn to walk on eggshells, but with every great performance you convice yourself it's worth it.
      • I've had Epsons in the past, none at current. Do they have a removable print mechanism yet? I was really happy with the output and the price, but the frequent clogs were horrible. Any time I didn't print for a few weeks, I had to flush it out to avoid stuck nozzles.

        I was no fan of their drivers, but thankfully either they or MS offered a version of the drivers wtihout the "helper" (ink salesman) apps.

        • No, they still clog if you let them sit for more than a few days to a week. I made up a small "rainbow" image in pshop (about 8"x1") and printed it to a file. I just copy that file to the printer on bond paper once every three or four days and it seems to keep things clear. I do the same with my 24" HP designjet plotter, as I don't use the color heads very often (the rainbow is 2" wide, and it prints on a 6" sheet, which is the smallest size for the roll-feed cutter). At one point I had them on the sched
          • Turn off your printer. I routinely go for weeks between prints, and I've only had the nozzles clog once -- I had neglected to turn the printer off. When you turn it off, the printer "parks" the heads in an air-tight "container." Since the ink doesn't dry out, no clogs.

            Actually, I did have the nozzles clog one other time -- I had used cartridges that weren't Epson brand, a mistake I've never made again.
            • I've tried it both ways - on and off. The ink dries out anyway in about 2 weeks and causes clogs. I had one I'd left off for about two months during a move, and when it powered back up, about 2/3 of the jets were clogged. After wasting a full set of ink (empty, replace, empty) there were still 3-4 that would not print. That's when I decided to switch to the keep-alive print. Besides, everytime you power up, it runs a bit of ink through the heads (I believe that the startup routine has not chaged in the late

          Canon is a good example of a company that actually takes the time to design it right, IMHO.

      I use Mpix.com for all my large printing needs. They are actually exposing the digital exposure to Kodak film paper which can be common among some people. Their price and service can't be beat either. 8x10s for $2.

      However if I need a 4x6, or a 8x10, a home printer is a decent deal. I recently picked up the Kodak 1400 [kodak.com] dye sub printer for just this reason. There was a $100 rebate so it's a $343 printer, and the paper size of 8x14 lets me print 4 4x6s, 2 5x7s, 2 6x8s, or one 8x10 or 8x12 per page. I won't be printing out a 'major event' like my son's 2nd birthday portrait or the disaster that was the attempt at my [fotki.com]daughters 4th birthday portrait [fotki.com] because I usually want a ton of wallets, a good amount of 4x6s, and 5x7s and 8x10s for the grandparents, my desk, what not.

      Fotki.com and the Kodak Easyshare Gallery have so far withstood that test rather well. However Kodak keeps making me sign a release form for every order for copyright reasons. Mpix does not, because there is no copyright displayed on my images. Apple has the same issue in iPhoto, but Kodak is their print engine. Fotki has been on the fridge for over a year now with no fading, next to a S9000 4x6 that is about as faded as it gets.

    A good tip I heard from a printer designer was to ignore the DPI figure, as long as it's more than about 600. It (usually) means how precisely the printer can place dots. It does not say much about the detail or grain you'll see in the print. For that, you need to know the dot size. Of course there's a trade off: smaller dots means (other factors being equal) longer print times, since you have to squirt more dots to get the same level of ink density.

    Higher end printers have several shades of grey ink as well as black. This can add a lot of the apparent smoothness of prints, especially if you are going to be printing any black and white photos.

    Metamerism is also very important. Print a black and white photo and look at it under tungsten and in daylight. It should stay looking black and white! You'll find some will look red in tungsten and greenish in daylight.

    Finally, look at color management. Does the driver let you use your own profiles, or is it more of a point and shoot thing?

      There is another issue, with so called photo printers. I don't know if this still holds true, so it would be good if someone could confirm this.

      With older technology printers, dots per inch is actually meaningful. It literally accounted for the number of non overlapping dots, each of which could be considered a pixel. However with these new bubble jet and ink jet type printers, they need to spit many very small ink dots into the area which makes up a printed pixel, so as to build up a single pixel of varying colour through the use of dithering.

      Fair enough right? Whatever needs to be done to make those images look great?

      Well unfortunately, these photo printer makers are using deceptive marketing. Because a "dot" in their definition of dpi DOES NOT equate in a meaningful manner to a pixel, instead their "dot" refers to each of the smaller dither dots.

      This is why for a long time, ink and bubble jets of 600dpi looked like crap against a 300dpi laser print out, where edge smoothness and text mattered.

      9600dpi, 2400dpi, whatever. Don't bother telling me because it is now a meaningless figure. You could make a printer with a real dpi of 150, but made up of 9600dpi dither dots and it is still going to look like a 150dpi print out. But the brochure says 9600dpi, not 150dpi. This is an exageration btw, to make the point. The best thing to do is look at actual print outs and decide on quality with your own eyes, because manufacturer quoted numbers in this regard are pretty much useless when the most important metric is undisclosed and remains so because it would hurt sales.
      • Yes, you're right. For inkjets ... it means pretty much zip. It's just a figure produced by marketing departments. Epson used to be very guilty of doing this, maybe they're better now.

        Another tip a printer designer told me :) don't think of DPI, think of PPPI, or Pixels Per Printed Inch. Try sending a photo to the printer at higher and higher resolution. At what point do you stop seeing a quality improvement?

        As a former product manager at an imaging OEM I can confirm that everyone should completely ignore "DPI" specs.

        What they also fail to mention is the paper requirements in order to produce a photo-quality image. It's got to hold a heck of a lot of ink, so there's very few papers capable of holding/controlling that much ink.

        A better predictor of "photo quality" is the number of inks.

        The other thing to watch out on is what the borderless performance really is. I work with a Canon that won't do borderless on plain paper, so if I have a document with tiny margins, it generally screws it up.

        At this point, I don't see a reason why it's really necessary when most photo processors do it arguably better, but on real photo paper that is much less resistant to fading.

      • > 9600dpi, 2400dpi, whatever.

        It's a good thing, then, that the FCC has limited the maximum DPI to 56600. (53000 in some areas.)

      • Reminds me of the time when they started inflating CDROM speeds, and you could no longer rely on the number behind the X. "36X CDROM??? Well we have 100X hahahahah!!!!!"
    • Yes, the DPI number is technically meaningless (some might say mostly harmless). What people really want is not DOTS per inch, but PIXELS per inch. Unfortunatly, that's not a number that is usually advertised, instead they give the deceptive dots per inch.

      First, let's look at the pixels... A standard consumer P/S and low end professional DSLR camera would take images at around 6MP (Nikon D70), a high end professional would be closer to 12MP (Nikon D2X)

      The 12MP D2X can take images at 4288 x 2848. Scaled land

    From TFA:
    No matter if you choose inkjet or "dye sub" printers, crisp detail and smooth color gradation are the keys to good prints. When you get your photos back from the lab, they're shiny and smooth (without lines or dots). Getting this quality at home depends on several factors including printer resolution, i.e., how many dots per inch (DPI) of ink the printer lays on the paper as well as paper quality......


    But I would never use inkjet, well anywhere. On photos because it would always smear and generally give out crappy results (you can see the intermittent lines). Plus it looks god-awful on regular paper and that ink cartridge dries out if you don't tend to regularly use it every few weeks.

    Except for the cheap paper bit, dye-sub doesn't have these problems and even a lower resolution looks better because it' more blended in. My dye-sub puts on a clear coat too so it has that professional look from the photo lab, not the cheapo inkjet look. And I can only print on photo paper with my dye-sub so the quality is kinda always forced on me:) but I don't mind. The cartridges aren't with ink so it can't dry out (the color layers are on a plastic and heat transferred to the paper).

    I use a Hiti printer (Hi-touch Imaging) which only focuses on these printers but they are good. I don't know if it supports linux but it's stand-alone anyway. Plus I find the price of consumables reasonable - fifty 4x6s and a dyesub cartridge bundled together for under 20 bucks.

    But whatever company somebody goes with, avoid inkjet! Plus my photos have a life of 99 years - I don't think the same can be said for inkjet (imagine that stored in someplace moderately humid).
    • Well, I think Epson would probably disagree with you on the longevity. I probably would, too, as I've had high end dye sub output look like the poster in the window of a beach popsicle stand in just a year or two (you know - all cyan with a touch of yellow here and there...not a hint of magenta to be found). The longevity figures are all artifically created, and DS mfrs are no more trustworthy than inkjet companies. Epson claims 108 (color) to 200 (b&w) years with their new pigment based inks. No, I do

    This is completely backwards. Smaller drops means more accurate placement, and the size of each drop likely has no effect on total ink dispensed since that's completely up to the controller that's spitting them out.

    I have two inkjet printers: a real cheap Epson Stylus 43SX and an Epson Stylus Photo R310. I use the 43SX for cheap color prints on ordinary paper and the R310 for photos.

    I have succeeded in installing the 43SX under Linux and and currently in the process of installing the R310 so it will run under Linux too. I have used the Epson R310 under Win2000 and the results are satisfactory.

    When printing to glossy paper the R310 prints look better than the prints I get from professional photo labs. Perhaps because I tend to tweak the colors and levels from my digicam using photoshop.

    According to my experience:

    • Print out a sample print from your digital camera and then adjust your monitor gamma so it will match the printer output. Now you can tweak the colors and levels ever so slightly and what you see on your monitor will be very close to the actual printer output.
    • If your camera has manual exposure controls, underexpose your shots slightly. You can always adjust the levels later with Gimp or Photoshop.
    • If you are going to visit the Philippines, there is a shop along Quirino Avenue where they modify your printer so it will accept a bulk inkflow system. They will remove the original Epson cartridges and attach ink cartridges that are connected to bottles containing printer ink. While your friends back in the states are complaining about the high cost of printer ink, you will giggle with delight as you pour ink into your bulk inflow system at a cost of only 20 dollars per liter per color!
