Refactor printing logic across multiple scripts to use method chaining for improved readability and consistency

- Updated Printer and PrinterPos instantiation to use method chaining with addParam instead of add_param.
- Refactored print functions in various modules including opname.js, pos.js, tukar.js, ppobtx.js, prabayar.js, and multiple report scripts.
- Enhanced code clarity and maintainability by standardizing parameter addition for print jobs.
