POS printers need to understand the parameters of the _ before the choose and buy equipment problems

POS printer belongs to special printer, it also has a special role. Usually in a restaurant, supermarket, convenience stores and other places with the special office equipment used POS cash register, so at the time of purchase, to the use of different functions have different methods of choose and buy. POS printer mainly use three kinds of printing technology: pin type printing, thermal printing, thermal transfer printing.

to choose the parameters of the POS printers need to understand before

choose POS printer before, the user can understand several main technical parameters, and then according to the requirements of practical application, to choose the right equipment, for the label printer system, resolution of the correct detection read in one of the most narrow width of operator, selecting equipment, not equipment points braid rate is higher, the better.

but should be used according to specific application in paper density has a corresponding resolution to select reading devices, if the selected equipment in the use of high resolution, is a blot on operator, deinking effect of the system will be more serious, such as scanning depth of field is on the premise of ensuring reliable reading, scanning head allowed to leave the longest distance between the surface can be the difference between the closest point on the surface of the near distance.

scanning speed is refers to the unit time scanning beam on the trace of scanning frequency, a recognition rate represents the first scan read the tag number and scanned the ratio of the total, from the view of the practical application of paper printers use, certainly hope every scan can pass.

effective scope of work is the label printer, some label printer equipment in the technical indicators are not given the scanning depth indicator, but given the scanning distance, namely the scan head allowed to leave the shortest distance, on the surface of the bar code scanning width index is given on the scanning beam scanning distance can read the information of the physical length value.
