When it comes to average specification mobile printers you can easily expect resolutions of around 4800 x 1200 dpi for the high quality photo print outs. These are indistinguishable from the high resolution four by six photographs which most people are used to. All of the printers for the last 5 years have had this resolution figure for color photo printing aside from the Canon PIXMA iP100 which has double that resolution, but the truth is whether it’s the figure I’ve just stated above that or double it you’re getting very high quality photographs.
One of the definite downsides however is in long it takes for these photographs to be printed out. The later models may have similar resolution figures but they’re almost all quite a lot faster. You can expect around 45-60 seconds for the latest wireless mobile photo printers – and around triple that for the older devices. What’s more is most inkjet devices are all capable of photo printing and this is in stark contrast to thermally based devices which can only print of medium to low quality color images.
Most of these devices also come with PictBridge which allows direct transfer of photograph data from the camera to the portable photo printer. This allows for very rapid printing because the files can sometimes be quite large and using usb 2.0 can be a slow process at times.
Regarding the wireless aspect of these devices you can expect to have to use either an external Bluetooth adapter or possibly mount this external adapter within the device in the case of only one of Canon’s latest wireless mobile inkjet photo printers. This may sound confusing but if you can imagine you’ll generally have either dongles or Compact Flash cards which are generally attached to external ports you will find that in some circumstances you’re able to mount these within the device. This has a number of advantages – the first being that it’s much less likely to be knocked out (especially in the case of a usb dongle) and it also looks far more aesthetically pleasing as opposed to a usb dongle sticking out horizontally.
One disappointing aspect about these types of wireless mobile printer devices is that they don’t come with their wireless capabilities already installed and can cost exorbitant prices. For example the Bluetooth adapters I just mentioned can easily cost around 40-70 dollars and the same is true of those which can connect to wireless access points such as those commonly found in airports or hotels. Another issue is that they don’t actually arrive portable because they don’t have batteries included within the price and these can cost a further 120 dollars.
One type of wireless connectivity which comes pretty much as standard now is infrared, although I don’t know how useful it’s going to be to everyone. The truth is it’s pretty outdate and although it did used to serve a function regarding data transfer from PDAs, those have been replaced with computer tablets that practically all utilize Bluetooth. All in all considering you don’t have to pay for it, it may come in use one day. Probably not though.
