printing

问题 I want to print an NSOutlineView. The view is a subview of a window on screen. I noticed the NSView api call printView. So I tried it in a simple minded fashion. In my AppDelegate I have a call: @IBAction func doPrint(_ sender: Any?) { globalOutlineCntrl?.outlineView.printView(self) } So with the window containing the outline on-screen, I issued the doPrint call. The outline on screen looks like this: The doPrint call seems to work, but prints this: Is there anyway to make this work? If not

问题 I have this code on windows which is working with A4 printers. But i have a very small printer, when i print something it does not print anything but only push the ticket out. TRY0: import win32ui X=0; Y=0 input_string = "Print 1234 test" multi_line_string = input_string.split() hDC = win32ui.CreateDC () hDC.CreatePrinterDC ('Dymo label printer') hDC.StartDoc ('FILE NAME FILE NAME') hDC.StartPage () for line in multi_line_string: hDC.TextOut(X,Y,line) #Y += 100 hDC.EndPage () hDC.EndDoc ()

问题 I have made a view that pretty much fits A4 page. Now I want to print it. Note that I am not using drawRect or anything like that, just a normal view with subviews and text labels. My problem is that I have a few views on that view which I use layers to put background colors and rounded rects around the items. The subviews don't print, but all text labels print. The _printReport is just a plain window with a view and bunch of text labels. What am I doing wrong and how could I do this better ?

问题 This question already has answers here : In Python interpreter, return without “ ' ” (2 answers) Closed last year . In the Python interactive prompt, if you return a string, it will be displayed with quotes around it. But if you just print the string, it will not be shown with quotes. Why? >>> a='world' >>> a 'world' >>> print(a) world 回答1: Simply put: The quotes allow python to treat whatever is inside of them as a 'string literal'; that way, if we wanted to write a string like 'print([0, 1,

问题 When I work with Python, I am used to work in a notebook environment (either Jupyter Notebook locally or Google Colab, where my examples below are tested). I am sometimes omitting the print() command when I am interested in a variable. Example: for each in ['a','b','c']: print(each) This prints a b c as expected. However, for each in ['a','b','c']: each doesn't print anything. If later I type in a new cell each , the notebook prints 'c' , as expected. If I write print(each) , I get c as

问题 I need to print an entire Z3 problem to debug it, but when I print it the output is truncated. from z3 import * s = Solver() ... Add many assertions to s ... print(s) How do I display everything? 回答1: Try: set_option(max_args=10000000, max_lines=1000000, max_depth=10000000, max_visited=1000000) You might want to play with actual values to come up with something that suits your needs. 来源： https://stackoverflow.com/questions/62008181/turning-off-z3py-print-truncation

问题 I have had a problem with printing a certificate with a background image and overlay text. My solution after much research is to convert a view to an image and print that and it works UNLESS the print dialogue is canceled then get a crash. I have tried many versions of the code, even a test app that only does the print function and always get the crash on canceling print. If the certificate is printed no apparent issues. following in one of many versions of the code I have tried, all with the

问题 I'm trying to set the paper feed in a NSPrintInfo object By now, I'm obtaining the paper feed options (from now on trays) from an IPP call ipp_t *request; request = ippNewRequest(IPP_GET_PRINTER_ATTRIBUTES); ippAddString(request, IPP_TAG_OPERATION, IPP_TAG_URI, "printer-uri", NULL, printer_uri); respose = cupsDoRequest(http, request, "/"); ... string trays = ippGetString(ippFindAttribute(response, "media-source-supported", IPP_TAG_KEYWORD), 0, NULL); This returns me a comma-separated string
