Most fully portable photo printers today offer wallet-size or slightly larger prints, so if you want a 4-by-6-inch picture size, which the Canon Selphy CP1500 offers, you have limited choices. Fortunately that doesn't mean you have to make compromises. The latest in the long-running Selphy line of portables, the CP1500 in particular delivers a solid feature set; drugstore-grade photo quality, courtesy of its dye sub technology; and a reasonably low running cost, at a bit above or below 30 cents per 4-by-6-inch photo. (The cost covers both the paper and required dye rolls.) Printing 5 * 5 dot matrix is fast, when printing graphics, Chinese, 16 dot matrix text, the speed is slow CONNECTIONS. Some portable photo printers offer a USB connection and can print from a computer. Most are designed primarily to print wirelessly from phones or tablets using manufacturer-supplied apps. Older models often include Wi-Fi Direct, and also PictBridge, to print from cameras that support it. But for printers that are designed to work with smartphones, Bluetooth is the most common connection method supported.

Portable photo printers are just what the name indicates: printers that are designed to work on battery power and are strictly for churning out snapshots. The key differentiator for these printers is the size of the prints.

With its own low-pressure gas supply system, the pressure of the gas source is stable, the quality is clean, and the normal operation of the machine is ensured. Handheld Full Color Printer, Mini Portable Wireless WiFi Printer for All Materials, Smallest Mobile… Because the printheads are so similar between both types of thermal printers, the output quality is similar as well. The key practical difference between the two types is that you have to buy special paper for the more common thermal printers, but don't need ribbons, while you have to buy ribbons for the thermal wax transfer printers, but don't need special paper. Note that the ribbons retain what amounts to a negative image of anything you print, which means that if you're printing anything meant to be private, you need to be careful where you discard them.The working principle of the handheld inkjet printer is similar to the high-resolution inkjet machine. It generally uses HP nozzles, using thermal bubble inkjet technology, the nozzle uses semiconductor thin-film technology, laser process, and high-precision coating technology are used to form a number of spray holes with a diameter of about 50 microns. These nozzles are arranged in high density. After receiving the heating signal, the ink is heated to about 260 °C by electric current in a very short time, and the local ink is heated to form bubbles to expand the ink, forming all kinds of characters such as words, pictures, LOGO, etc.

Because the label rolls are generally continuous, the time per label depends on the length, and the printers are rated in millimeters (mm) per second or inches per second (ips). Actual speed in our tests is usually slightly slower than the rating, but print time isn't the only factor to consider.The hand-held inkjet printer controls the inkjet through the ink path and the circuit, so as to achieve a certain printing speed through the dot matrix arrangement of the high-definition nozzle. The printing accuracy is high, and more than 200 fonts can be printed. Additionally, many portable printers come with nice-to-have features such as scanning and simultaneous connection to multiple devices. How We Selected
