Visual Basic adalah salah satu bahasa pemrograman berbasis desktop yang dikeluarkan oleh perusahaan perangkat lunak komputer terbesar, yaitu Microsoft. Visual basic merupakan salah satu bahasa pemrograman paling laris dan sukses di dunia. Dimana tercatat sampai tahun 2005 visual basic merupakan bahasa pemrograman yang paling banyak dipakai oleh para programmer. Menjadi pilihan berbagai kalangan, tentunya Visual Basic memiliki berbagai hal yang patut dijadikan alasan, selain bahasa pemrograman yang sangat mudah dipelajari oleh berbagai kalangan baik pemula maupun ahli, visual basic didukung penuh oleh produsennya (Microsoft) selalu dikembangkan dan disesuaikan dengan kebutuhan zaman seperti penyesuaian model pemrograman modern yang berbasis OOP (Object Oriented Programming) Berikut link untuk mendownload offline installer Visual Basic. Thank you very much, David. But your code has the same problem, it reports the status of the queue, not the physical printer. For example, after I cleared the print queue and emptied the paper box of the printer, I expect to recieve a 'Out of paper' status when running this function. However, either win32 api or.net framework just returns 'ok' status, which is actually the status of the queue. I'd been looking all around for a solution until i found the following artical in msdn: In this article, MS says: 1. NOTE: You cannot communicate directly with the physical printer. ![]() You should not have to do this because the operating system must arbitrate access to the hardware. NOTE: The system only checks the status when the system has a job to spool. Otherwise, the queue is considered 'ready' because the queue can accept jobs, even if the hardware is in an error state. For example, if the last job that was printed used the last piece of paper, the operating system does not know this until the system tries to print again. So I'm now wandering if there is no way to know under a windows system the actual status of a physical printer, not the queue, the spooler or anything else. 39.1 Printing using the Printer object In previous lessons, we have only written programs that send output to the screen and not the printer. In this lesson, we will learn how to send an output to the printer and get it printed. Sending output to the printer is a simple task in Visual Basic, it involves the use of the Printer object and the Print method. The standard code of sending an output to the printer and get it printed out is as follows: Private Sub Form_Load() Printer.Print'Welcome to Visual Basic' End Sub However, the code above only send the output to the printer without actually printing it. It will only print the output when you terminate the application.To solve this issue, we need to add the newpage or EndDoc method, as follows: Private Sub Form_Load() Printer.Print'Welcome to Visual Basic' Printer.EndDoc End Sub Beside printing messages in string form, you can actually print out other variables including numeric values. Below is an example: Private Sub Command1_Click() Dim x, y As String, z As Variant x = InputBox('Enter the first Number') y = InputBox('Enter the second Number') z = Val(x) + Val(y) Printer.Print 'The answer is' & z Printer.EndDoc End Sub If x=3 and y=4, the printing output is 'The answer is 7' You can also use loops to send output to the printer. In the follow example, I used the For.Next loop to print out the multiplication table. Private Sub Command1_Click() Dim i, j As Integer For i = 2 To 9 For j = 2 To 9 Printer.Print i & 'x' & j &' ='& i * j Next j Printer.Print Chr(13) Next i Printer.EndDoc End Sub The command Printer.Print Chr(13) is equivalent to pressing the Enter key and print the output on the next line. The output is as follows. 2x2=4 2x3=6 2x4=8 2x5=10 2x6=12 2x7=14 2x8=16 2x9=18 3x2=6 3x3=9 3x4=12 3x5=15 3x6=18 3x7=21 3x8=24 3x9=27 4x2=8 4x3=12 4x4=16 4x5=20 4x6=24 4x7=28 4x8=32 4x9=36 5x2=10 5x3=15 5x4=20 5x5=25 5x6=30 5x7=35 5x8=40 5x9=45 6x2=12 6x3=18 6x4=24 6x5=30 6x6=36 6x7=42 6x8=48 6x9=54 7x2=14 7x3=21 7x4=28 7x5=35 7x6=42 7x7=49 7x8=56 7x9=63 8x2=16 8x3=24 8x4=32 8x5=40 8x6=48 8x7=56 8x8=64 8x9=72 9x2=18 9x3=27 9x4=36 9x5=45 9x6=54 9x7=63 9x8=72 9x9=81 Now you might want to know whether is it possible to print the content of text file created in Visual Basic?
