Python打印文件 Python调用Windows命令打印文件
人气:01、Python调用Windows命令打印文件
Windows命令行打印文件使用print 命令,具体用法可使用help print查看。下面是使用Python调用print指令执行打印文件功能的代码:
import os def printer(filename): printername = r"/D:\\A340\hpLaser" cmd = "print " + printername + " " + filename print "print cmd:", cmd if not os.system(cmd): print "printing..." else: print "some error occurs." if __name__ == "__main__": filename = raw_input("Please input your filename:\n") printer(filename)
这里的打印机用的是共享打印机,所以需要指定域名和打印机名称,而且"/D:"表示的是打印设备的意思。
2、windows下如何用python控制打印机打印
首先下载python需要的库
pip install pypiwin32
简单例子
import tempfile import win32api import win32print filename = tempfile.mktemp (".txt") open (filename, "w").write ("This is a test") win32api.ShellExecute ( 0, "print", filename, # # If this is None, the default printer will # be used anyway. # '/d:"%s"' % win32print.GetDefaultPrinter (), ".", 0 )
import win32print import win32ui import win32con def print2Printer(): INCH = 1440 hDC = win32ui.CreateDC () hDC.CreatePrinterDC (win32print.GetDefaultPrinter ()) hDC.StartDoc ("Test doc") hDC.StartPage () hDC.SetMapMode (win32con.MM_TWIPS) hDC.DrawText ("TEST HELLO WORLD! CORSS FIREWALL, WE TOUCH THE WORLD!", (0, INCH * -1, INCH * 8, INCH * -2), win32con.DT_CENTER) hDC.EndPage () hDC.EndDoc () print2Printer()
若在hDC.DrawText()中传的是空字符串,则可以实现空走纸。
但实际上这只是打印自己制定的字符串, 并且打印出来会显示txt的文件名。所以我更倾向于使用windows的cmd指令打印指定文件。
3、Python利用win32连接打印机自动打印
import win32print import win32ui from PIL import Image, ImageWin #物理宽度、高度 PHYSICALWIDTH = 110 PHYSICALHEIGHT = 111 #物理偏移位置 PHYSICALOFFSETX = 112 PHYSICALOFFSETY = 113 printer_name = win32print.GetDefaultPrinter () #选择图片路径 file_name = “biaoqian.png” hDC = win32ui.CreateDC () hDC.CreatePrinterDC (printer_name) printer_size = hDC.GetDeviceCaps (PHYSICALWIDTH), hDC.GetDeviceCaps (PHYSICALHEIGHT) #printer_margins = hDC.GetDeviceCaps (PHYSICALOFFSETX), hDC.GetDeviceCaps (PHYSICALOFFSETY) #打开图片 bmp = Image.open (file_name) print(bmp.size) ratios = [1.0 * 1754 / bmp.size[0], 1.0 * 1240 / bmp.size[1]] scale = min (ratios) print(ratios) print(scale) hDC.StartDoc (file_name) hDC.StartPage () dib = ImageWin.Dib (bmp) scaled_width, scaled_height = [int (scale * i) for i in bmp.size] print(scaled_width,scaled_height) x1 = int ((printer_size[0] - scaled_width) / 2) y1 = int ((printer_size[1] - scaled_height) / 2) #横向位置坐标 x1 = 1580 #竖向位置坐标 y1 = 30 #4倍为自适应图片实际尺寸打印 x2 = x1 + bmp.size[0]*4 y2 = y1 + bmp.size[1]*4 dib.draw (hDC.GetHandleOutput (), (x1, y1, x2, y2)) hDC.EndPage () hDC.EndDoc () hDC.DeleteDC ()
4、python chrome调用打印的样例
python selenium 控制chrome 调用打印的时候会找不到元素,控制不到的情况
# 点击打印 wait.until(ec.presence_of_element_located((By.LINK_TEXT, "打印"))).click() # 父窗口 类名: Chrome_WidgetWin_1 标题: 中行网银(香港) - Google Chrome father = win32gui.FindWindow(None, '中行网银(香港) - Google Chrome') # 子窗口 类名: Chrome_RenderWidgetHostHWND 标题: Chrome Legacy Window son = win32gui.FindWindowEx(father, None, "Chrome_RenderWidgetHostHWND", 'Chrome Legacy Window') # 设置为最前窗口 win32gui.SetForegroundWindow(son) time.sleep(1) # ctrl+P win32api.keybd_event(17, 0, 0, 0) win32api.keybd_event(80, 0, 0, 0) win32api.keybd_event(17, 0, win32con.KEYEVENTF_KEYUP, 0) win32api.keybd_event(80, 0, win32con.KEYEVENTF_KEYUP, 0) time.sleep(1) # ctrl+shift+P win32api.keybd_event(17, 0, 0, 0) win32api.keybd_event(16, 0, 0, 0) win32api.keybd_event(80, 0, 0, 0) win32api.keybd_event(17, 0, win32con.KEYEVENTF_KEYUP, 0) win32api.keybd_event(16, 0, win32con.KEYEVENTF_KEYUP, 0) win32api.keybd_event(80, 0, win32con.KEYEVENTF_KEYUP, 0) time.sleep(1) # 发送回车-确认打印 win32api.keybd_event(13, 0, 0, 0) win32api.keybd_event(13, 0, win32con.KEYEVENTF_KEYUP, 0) time.sleep(1) # 关闭子窗口 windows = browser.window_handles browser.switch_to.window(windows[1]) wait.until(ec.presence_of_element_located((By.NAME, "close"))).click() # 切回父窗口 browser.switch_to.window(windows[0]) print(browser.page_source) # 点击返回 wait.until(ec.presence_of_element_located((By.LINK_TEXT, "返回"))).click() print("print end")
另一种方法,调用pdf打印,代码如下:
import win32api import os import json #PRINTER_NAME = '\\\\cnsz02vw00397\\CM_Printer_1' #PRINTER_NAME = 'Xerox Phaser 3435 PCL 6' def print_pdf(pdf_file_name): with open(os.getcwd() + "\\config_generate.json", "r", encoding="utf-8") as f: json_data = json.load(f) PRINTER_MACHINE = json_data["print_machine"] f.close() PRINTER_NAME = PRINTER_MACHINE """ 静默打印pdf :param pdf_file_name: :return: """ GHOSTSCRIPT_PATH = os.getcwd() + '\\GHOSTSCRIPT\\bin\\gswin32c' print(GHOSTSCRIPT_PATH) #currentprinter = config.printerName currentprinter = PRINTER_NAME # currentprinter = win32print.GetDefaultPrinter() arg = '-dPrinted ' \ '-dBATCH ' \ '-dNOPAUSE ' \ '-dNOSAFER ' \ '-dFitPage ' \ '-dNORANGEPAGESIZE ' \ '-q ' \ '-dNumCopies=1 ' \ '-sDEVICE=mswinpr2 ' \ '-sOutputFile="\\\\spool\\' \ + currentprinter +"\""+ " " + \ pdf_file_name #log.info(arg) win32api.ShellExecute( 0, \ 'open', \ GHOSTSCRIPT_PATH, \ arg, \ ".", 0 ) if __name__ == '__main__': aaa = 'D:\\tempFile\\2019-09-12\\pay\\print.pdf' print_pdf(aaa)
这里就差不多了
