Under normal circumstances, the pos Printer generally needs to be connected with the POS system. If the PDF file is directly printed, the problem of incomplete printing will occur. Because the POS Printer is generally 2inch or 3inch, and the PDF document is generally A4 size, it will appear that the printing is completely organized.
If it is on an Android tablet, we need to install a pos printer service App (CPPrintService.apk)
Step 1: Install CPPrintservice.apk
Step 2: Connect to POS Printer
Step 3: Open the PDF document to be printed, select share---Share to CPPrintService
Step 4: Select Print
