LG PD233 Pocket Photo LG's pink or silver wireless printer (HK$1,099, electrictung.com ) uses short-range radio tech called NFC to link to Android smartphones and tablets. A "tap" sends the information over Bluetooth for printing. The slick LG Pocket Photo App lets you edit images before printing, as well as add text and share on social media. Great quality 313 DPI 50mm x 76mm colour photos are printed in less than 45 seconds on heat-activated 50 x 76mm Zink paper, which is costly at HK$90 for 30 sheets. Highly portable, the PD233 measures 72mm x 24mm x 121mm and weighs 212 grams. Fujifilm Instax Share SP-1 Just as pocketable as the LG at 102mm x 42mm x 122mm and weighing in at 253grams, the Instax Share SP-1 (HK$1,290, yohohongkong.com ) uses Wi-Fi Direct and the free Instax Share app to transfer photos from a phone. Its 254 DPI, 62 x 46mm photos are more personal, with the date, place, weather, temperature and humidity printed on the frame. It's also possible to create a social media print that includes the number of likes. However, the paper costs about HK$60 for just 10 prints. Canon SELPHY CP910 At 178mm x 127mm x 605mm and 810 grams, the SELPHY (HK$1,280, foresoon.com.hk ) is much larger. It prints images at 300DPI in 47 seconds. As well as larger postcard-sized photos, it can print credit card-sized stickers and various other sizes. The paper costs HK$88 for 36 prints. Wi-Fi Direct (a direct wireless link, which cuts out the need for a home network and router passwords) transfers images using the Canon Easy-PhotoPrint app. It also accepts SD cards and USB sticks with Apple's AirPrint.
