In the barcode scanning industry, handheld devices such as PDAs, scanners, and smart POS machines are often used as core devices for data collection. The scanning dock integrated in these devices, that is, the QR code embedded scanning head or the 2D barcode scanning module, can quickly complete the collection of barcode data. These devices usually scan barcodes and translate black and white stripes of different widths into corresponding codes for computer recognition and management.

When using handheld devices for data collection, importing screen parameter data is an important step. This step is mainly to ensure the accuracy and consistency of the scan results. By importing screen parameter data, the scanning parameters of the device can be adjusted to match the resolution, color and other characteristics of the display screen, thereby ensuring that the scanned barcode information is consistent with the content on the display screen.

Specifically, importing screen parameter data usually includes the following steps:

Get screen parameters: Get the resolution, color depth, screen size and other information of the display screen.

Adjust scanning parameters: Adjust the scanning parameters of the device according to the screen parameters, such as scanning accuracy, scanning range, etc.

Testing and calibration: Ensure the accuracy of scanning parameters by comparing test scan results with actual display content.

Application settings: Apply the calibrated parameters to actual data collection work to ensure that the collected data is consistent with the display content.

The general steps for importing screen parameter data into the price checking machine are as follows:

Open the setting interface of the price check machine and enter the communication and screen parameter settings.

Make sure the USB flash drive is connected to the computer and select parameter settings.

Adjust the scanning parameters of the price checker according to the screen parameters of the device, such as resolution, color depth, etc.

Test and calibrate scan results to ensure they match actual display content.

After completing the settings, save the parameters and close the setting interface.

It should be noted that the specific operation steps may vary depending on different brands and models of price checking machines. Therefore, it is recommended to refer to the price check machine user manual or contact the manufacturer's technical support to ensure the correctness and accuracy of the operation.
