问题 a = input() b = input() print(a+b) This can be written as print(input()+input()) and it works. How does it work? Where are the inputs are stored temporarily? 回答1: Premise: input() is just a normal function that blocks until the user types something in. Once that is done, the data is evaluated and returned. With that set aside, your statement is composed of several parts: print(...) is a function call that prints the result of the expression that is between its parentheses. The expression then

问题 I need to automatically print a PDF file to a file (need to have printer driver set all the print options like stapling, duplexing, etc) on a network folder so other employees can print the .prn file from networked printers.

I could

问题 I want to print a page (or some pages) from an iPad app I'm developing.

问题 I'm writing a simple app in Android to print through a ESC/POS thermal printer. I've just a problem. The app generate a QR Code (with zxing library), convert it in a bitmap and send it to the printer. The printer print it, but I'm not able to center it. Instead with text I have no positioning issue. This is the code to print the text and the QR. byte[] INIT = {27, 64}; byte[] FEED_LINE = {10}; byte[] SELECT_FONT_A = {27, 33, 0}; byte[] FONT_B = {0x1B, 0x4D, 0x01}; byte[] ALLINEA_SX = {0x1B,

问题 I'm using css to only print a section of a page: body { visibility:hidden; } .print { visibility:visible; background-color: white; margin: 0; } The section above the element I want to print gets properly hidden in the print output, however it still takes up the area of space. I tested this by making a long vertical list of words. In the print output the same area of white space occurs without the words and then the element output occurs. This problem occurs on chrome and mozilla only. I've
