My full class looks like this: class CSTSummaryViewController: UIViewController { @IBOutlet weak var summaryReport: UITextView! @IBAction func Print(sender: AnyObject) { let printController =

问题 I actually want to print the content of the dx register with nasm. Thereby the content is a 16 bit hex digit such as 0x12AB. Therefore I've first implemented a function which is able to print a string: print_string: pusha mov ah, 0xe print_character: mov al, [bx] inc bx or al, al jz print_done int 0x10 jmp print_character print_done: popa ret You can use this function in this way: mov bx, MSG call print_string MSG: db 'Test',0 Now i want to have a function, which converts the hex to a string,

问题 I am using a plugin jsPDF which generates PDF and saves it to local file system. Now in jsPDF.js, there is some piece of code which generates pdf data in blob format as:- var blob = new Blob([array], {type: "application/pdf"}); and further saves the blob data to local file system. Now instead of saving I need to print the PDF using plugin node-printer. Here is some sample code to do so var fs = require('fs'), var dataToPrinter; fs.readFile('/home/ubuntu/test.pdf', function(err, data){
