使用python pycups cups如何设置自定义页面大小的边距

Question

下面是使用 pycups 的脚本，我可以使用自定义页面尺寸进行打印，但我需要设置边距以及如何做到这一点。

import cups

def print_to_printer(printer_name, file_path, custom_width=720, custom_length=432):
    conn = cups.Connection()

    # Get the printer information
    printer_info = conn.getPrinterAttributes(printer_name)

    # Convert inches to points (1 inch = 72 points)
    custom_width_points = str(int(custom_width * 72))
    custom_length_points = str(int(custom_length * 72))

    # Create the page size string
    page_size_str = f"{custom_width_points}x{custom_length_points}"

    # Start the print job with custom page size
    print_options = {'PageSize': page_size_str}
    print_job_id = conn.printFile(printer_name, file_path, "Print Job", print_options)

    print(f"Print job {print_job_id} sent to {printer_name} with custom page size ({custom_width}x{custom_length} inches)")

# Example usage
printer_name = "TVS_MSP-250CH-TVS-original"  # Replace with your actual printer name
file_to_print = "/home/tk/Documents/bill.txt"  # Replace with the path to your file
custom_width = 10  # Replace with your desired width in inches
custom_length = 6  # Replace with your desired length in inches
print_to_printer(printer_name, file_to_print, custom_width, custom_length)

Answer 1

创建一个新的

cups.Page

对象。

设置打印页面的边距。 传递给

setMargins

的值以磅（1/72 英寸）为单位。 这里我们将所有四个边距（上、下、左、右）设置为 72 点，相当于 1 英寸。

page = cups.Page(...)

page.setMargins(72, 72, 72, 72)  

conn.printFile(printer_name, page, "My Print Job", {})

上面编写的代码片段创建一个新的页面对象并设置其边距，然后将打印作业发送到指定的打印机。
