Handheld printer is to miniaturize and portable printers commonly used in offices. It is mainly aimed at business people who often travel or go out, so that they can print various office documents in non-fixed office places such as hotels, cafes and other places with portable computers. Due to technical limitations, at present (up to early 2010) only ink jet and heat sensitive technologies are applied to office portable printers. Due to the complicated structure, the volume of laser printers commonly used in offices cannot be reduced to a portable level. However, even though the volume of ink jet and thermal portable printers is small enough for the technologist, it is still too large and heavy for the user. It is hard to imagine that many people will bring portable computers and portable printers at the same time when traveling on business. The widespread use of office portable printers also depends on the improvement of technology and design. Printing technologies used include ink jet and heat sensitivity. Ink-jet consumables are plain paper, generally a6 size; Heat-sensitive consumables are heat-sensitive paper with smaller size: battery powered, much smaller than ordinary printers, and heat-sensitive ones are smaller. Disadvantages of portability: the size is still too large, although it can be carried, it is quite inconvenient. Ink-jet consumables are also a bit too expensive to cooperate with the host computer: desktop/notebook portable photo printers are mainly used to print photos when traveling, and of course they can also be used at home. It mainly adopts thermal sublimation technology and ink-jet technology, and uses consumables as special photo printing paper.
Now let us talk about how to protect the screen during we use the touch screen Handheld printer. First, If the display resolution or display mode of the touch screen is changed again when the capacitive touch screen is operated in the middle, or the refresh frequency of the touch screen controller is adjusted by itself, and it is felt that the cursor cannot correspond to the touch point, the touch screen system must be calibrated again. Second, In order to ensure the normal operation of the touch screen system, in addition to ensuring the correct installation of system software, it is also necessary to remember not to install two or more kinds of touch screen drivers on a host computer, which will easily lead to conflicts during system operation, thus making the touch screen system unable to be used normally. Third, Don't let water drops or other soft things stick to the surface of the touch screen, otherwise the touch screen is easily mistaken for the surface acoustic wave screen caused by hand touch. In addition, when cleaning dirt on the touch screen surface, you can carefully wipe it outward from the center of the screen with a soft dry cloth or detergent, or dip a dry soft cloth in industrial alcohol or glass cleaning solution to clean the touch screen surface.
