Card printing technology
The so-called card printing is integrated on the printer, and the printer reads photos directly from the memory card and prints without PC. Today, there are too many types of memory cards in the market, and there are different specifications such as CF, CFII, SD, SM, MMC, XD, MS, etc., and there is a minimum of various specifications. This brings inconvenience to the configuration card reader. In the technical implementation of specific products, the manufacturer's approach is to support a part of the mainstream memory card format, such as CF, SD, MS, XD, etc., or simply all compatibility. Another puzzle of the card print is a preview of the photo. The black and white liquid crystal display clearly cannot complete this heavy, so many photo printers are also integrated with a color LCD display to preview photos, although the liquid crystal display increases, but it is convenient to bring consumers. Intuitive. Some card readers do not have a product that does not have a LCD screen. A photo printer without card printing features presents two-level differentiation, and the product is at both ends of the industrial chain.
Direct printing technology
The practice of direct-in printing technology is to connect digital cameras and photo printers to photos printed. Both digital cameras and printers have a USB interface, which makes direct printing on communication interfaces. In the early, different manufacturers have launched different direct-connected print protocols, and various protocols are incompatible, causing many digital cameras to print protocols of printers, and the market order is very confusing. In order to standardize direct-in printing technology, Direct Printing Technical Specifications for the whole industry - Pictbridge appears. Now Canon, Epson has joined the support of Pictbridge's standard in the new photo printer product, and digital camera manufacturers have also joined the support for this standard in new digital cameras, as long as they are in the product. The printers and digital cameras with this marker on the package can be directly connected.
There are also some CD drivers, Mo, ZIP drives such as foreign countries, and some specification standards make it connectable to the photo printer to achieve direct printing.
Wireless printing technology
The bondage of getting rid of the wired is the development direction of many IT products. Numerous wireless transport protocols have been developed and implanted into related products. The main one of these technologies is 802.11a / b / g WiFi, Bluetooth, and infrared. 802.11 As a standard for wireless local area networks, it has now been integrated into countless centrino laptops. For photo printers, a small number of products have built a module that supports 802.11 protocols, and for a photo printer that does not support 802.11 protocol, the wireless photo print is also very simple, and there is a lot of wireless print servers on the market, as long as Connections, you can easily implement WiFi-based wireless photos printing. For hand-held devices such as mobile phones and PDAs, they can basically have a Bluetooth or an infrared interface that can be used to perform data transmission, and some avant-garde photos printers are built-in or can load Bluetooth, infrared communication interfaces, and implement mobile handheld Photograph of the device prints.
