printing

问题 I'm trying to print a pdf file from Python with module win32print but the only way I can print success is a text. hPrinter = win32print.OpenPrinter("\\\\Server\Printer") filename = "test.pdf" try: hJob = win32print.StartDocPrinter(hPrinter, 1, ('PrintJobName', None, 'RAW')) try: win32api.ShellExecute(0, "print", filename, None, ".", 0) win32print.StartPagePrinter(hPrinter) win32print.WritePrinter(hPrinter, "test") # Instead of raw text is there a way to print PDF File ? win32print

问题 I have implemented print preview functionality within my application using a custom DocumentViewer (shown below). I call PrintDialog.ShowDialog() before showing the preview so as to correctly create the document based on paper orientation. The DocumentViewer print button however calls the PrintDialog.ShowDialog() prompting the user to chose printer and options once again (which they already did prior to the preview window opening). Is there a way to have the DocumentViewer print button simply

问题 I have a page with a structure similar to this: <main> <section> <article></article> <aside></aside> </section> </main> In the CSS, I include the following: main { display: flex; flex-direction: row; } The article is often many pages long. When I print or print preview, I find that it only gives me the first page or so. After some experimenting, I have got this solution: @media print { aside { display: none; } main { display: block; } } That is, by using display: block I can get all of the

问题 Say I take an integer assigned to $a0, how do I go about and print the integer in its Hexadecimal form? 回答1: Use syscall 34. MARS syscalls If you are using a simulator which does not have that syscall, or you want to see only the necessary bytes, you will need to do it manually. The easiest approach would be iterative. Get a string of 10 bytes (8 hex values and leading 0x). 1) Bitwise and $a0 with constant 15. 2) Convert result to equivalent hex value in ASCII. A lookup table would be clean

问题 I have code in a C program with hex data which I want to iterate over, for example to print out each of the hex bytes: char input[] = "\x31\xd2\xb2\x30"; for (int i = 0; i < strlen(input); i++) { printf("%02X\n", input[i]); } However, the output is not what I expect, for example the above prints: 31 FFFFFFD2 FFFFFFB2 30 I also tried to cast the output as an (unsigned int) , however I receive the same output. Can somebody point out the issue with this simple script? 回答1: The arguments passed

问题 I have a printf statement after sleep for 1 second. Since the printf statement takes longer than 1 second , the refresh rate is more than 2 seconds. Here is an example i am talking about : while(1){ printf("%s",buf);//Takes more than one second to print a table. Only few //values are updated sleep(1); } How can i have a printf to be non blocking. Is there a way in a standard linux machine ? -Sanatan 回答1: If you only care about what shows on the screen, that is one of the problems that curses

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
