printing

问题 Ok, so I'm pretty sure this isn't even possible, but I have a friend whose client is basically begging him for an answer on this so I told him I'd get some input from the friendly folks here at SO. His client is ULTRA-PICKY about pixel precise user interface design across all browsers (IE7+, FF, Chrome and Safari). They have TEAMS of people in other countries who do nothing but sit there and measure to make sure everything matches their UX style guide down to the pixel in all browsers

问题 We have an old Print driver which takes a document and sends PCL to the spooler. The client then processes this PCL and displays everything as TIFF. Our users have been complaining that the TIFF is fuzzy and the image is not sharp. I am given this stupid task of solving the mystery Is the PCL itself bad. I don't have enough knowledge about a PCL and if it has resolution. How do I trap the output of a driver that's being sent to the spooler? Or is it the client that is somehow not rendering

问题 i have an Epson-TMH6000III thermal printer and i want to print some bitmap with it by using ESC/POS commands. but before this i want to print a very simple single line with ESC/POS printing image commands. here's my attempt : namespace printingImageMode { class Program { static void Main(string[] args) { Bitmap bmp = new Bitmap(@"C:\Users\falamarzi\Desktop\Kyan Graphic Viewer\jTest.jpg"); int msb = (int)(bmp.Width & 0x0000ff00) >> 8; int lsb = (int)(bmp.Width & 0x000000ff); byte msbB =

问题 So far I've found two different ways to access what I believe are equivalent versions of the Printer DevMode from a wxPython User Interface: window = wx.GetTopLevelWindows()[0].GetHandle() name = self.itemMap['device'].GetValue() # returns a valid printer name. handle = win32print.OpenPrinter(name) dmin = None dmout = pywintypes.DEVMODEType() mode = DM_IN_BUFFER | DM_OUT_BUFFER | DM_IN_PROMPT res = win32print.DocumentProperties(window, handle, name, dmout, dmin, mode) if res == 1: print dmout

问题 This question already has answers here : Show DataFrame as table in iPython Notebook (7 answers) Closed 10 months ago . I've seen a lot of very helpful posts on using prettyprint and such; they have been very helpful -- thanks. What I'm wondering if there is anyway to print a dataframe from a function and have it output as "prettily" as Jupyter notebook does: My main reason is I would like to use pandas's styling functions to highlight/shade. I also want to print from a function and not a

问题 here there is my code: https://github.com/Franco7Scala/RestrictedAreaImageAdversarialAttack/tree/master/src You should see test_attack.py and l2_attack.py. Now we can go to the problem, in this place of l2_attack-py: mask = tf.ones((batch_size, image_size, image_size, num_channels), tf.float32) # Get input shapes modifier_shape = tf.shape(modifier) mask_shape = tf.shape(mask) # Make indices grid oo, ii, jj, kk = tf.meshgrid(tf.range(modifier_shape[0]), tf.range(modifier_shape[1]), tf.range

问题 First of all, I've searched SO and there is no working solution I have some long content, and I want to have footer only on last page. I tired: 1) .footer{ position: absolute; bottom: 0; } If puts footer at the end of first page only. 2) As old answers suggest @page :last But :last doesn't exist (as I see from old answer it existed). 3) Normal footer, sure it is shown on the end of all pages.
