python - 尝试使用 ZPL 到斑马打印机进行打印

Question

所以我尝试使用 ZPL 语言打印到斑马打印机，但是当我运行下面的代码时，我得到的只是空白标签，知道为什么它不读取 ZPL 变量“标签”。我已将代码放入标签中，它看起来是正确的，但我无法让它打印 ZPL，它只是空白标签。

    import os
from PIL import Image
import zpl
from zebra import Zebra

lines = []
with open(
        r'C:\Users\matthew.vandruff\Downloads\Hard Drives (version '
        r'1)-b0dd6970-7dfd-4bb7-b04d-fc9c3ff4bc8a-a54c9c76-f7e2-40b1-8ff4-6d7eec1c99bb.csv') as f:
    for line in f.readlines():
        l, name = line.strip().split(',')
        lines.append((l, name))

list = lines
x = 1
while x < len(list):
    HD_Serial, HD_Number = list[x]
    # print(HD_Serial, HD_Number)
    x += 1

l = zpl.Label(100, 60)
height = 0
height += 5
l.origin(30, height)
l.write_barcode(height=70, barcode_type='C', check_digit='Y')
l.write_text(f'{HD_Number}')
l.endorigin()

height += 0
image_width = 12
l.origin((l.width - image_width) / 3, height)
image_height = l.write_graphic(
    Image.open(os.path.join(os.path.dirname(zpl.__file__), 'MTC_Logo.png')),
    image_width)
l.endorigin()

height += image_height + 5
l.origin(15, height)
l.write_barcode(height=70, barcode_type='C', check_digit='Y')
l.write_text(f'{HD_Serial}')
l.endorigin()

print(l.dumpZPL())

z = Zebra()
Q = z.getqueues()
z.setqueue(Q[0])
z.setup()
z.autosense()
z.output(l)

所以我猜我的问题出在打印机的设置上，但这是我的最终工作代码，供任何前来查看的人使用，并且在尝试打印时只会出现空白。

import os
from PIL import Image
import zpl
from zebra import Zebra

lines = []
with open(
        r'C:\Users\matthew.vandruff\Downloads\Hard Drives (version '
        r'1)-b0dd6970-7dfd-4bb7-b04d-fc9c3ff4bc8a-a54c9c76-f7e2-40b1-8ff4-6d7eec1c99bb.csv') as f:
    for line in f.readlines():
        l, name = line.strip().split(',')
        lines.append((l, name))

list = lines
x = 1
while x < len(list):
    HD_Serial, HD_Number = list[x]
    # print(HD_Serial, HD_Number)
    x += 1



l = zpl.Label(100, 100)
height = 0
height += 15
l.origin(23, height)
l.write_barcode(height=80, barcode_type='C', check_digit='Y')
l.write_text(f'{HD_Number}')
l.endorigin()

height += 0
image_width = 12
l.origin((l.width - image_width) / 10, height)
image_height = l.write_graphic(
    Image.open(os.path.join(os.path.dirname(zpl.__file__), 'MTC_Logo.bmp')),
    image_width)
l.endorigin()

height += image_height + 5
l.origin(5, height)
l.write_barcode(height=80, barcode_type='C', check_digit='Y')
l.write_text(f'{HD_Serial}')
l.endorigin()

label = l.dumpZPL()
l.preview()

z = Zebra()
Q = z.getqueues()
z.setqueue(Q[0])
z.setup()
z.output(label)
