print "Hello, World!"

Question

Yes, really. Print it with a hardware printer 🖨 to create a hard copy.

Send the necessary commands/data to your printer such that the following text is printed on a piece of paper:

Hello, World!

You may use any local- or network-connected printer that is available to you.

If your printer allows, you should use 8pt or greater text in black ink on white paper.

The text should appear on its own line. It may be left or right positioned as you wish.

Digital photographic/video/GIF evidence of submissions will be helpful.

If your hardware cannot do paper, but allows other exotic hardcopy production such as 3D printing, CNC machining, or printing at the atomic level, then I will happy to accept such interesting submissions.

To clarify, the question asks "Send the necessary commands/data to your printer". The implication of this is that no further user input should be required. Opening a print dialog is not sufficient. Existing answers that do this as of 10:48am PST 31st Dec 2016 will be grandfathered (but not upvoted by me).

Please supply address to which we can send submissions for verification. — steenbergh, Commented Dec 30, 2016 at 21:38
@steenbergh Yep - good point - Digital photographic/video/GIF evidence of submissions should be good enough. — Digital Trauma, Commented Dec 30, 2016 at 21:41
It's worth noting that many older printers use custom command sets. Most of these print ASCII characters literally, so if you have access to one of the printers in question (or can just claim that you do), sending Hello, World! to the printer port should be enough. — user62131, Commented Dec 30, 2016 at 22:30
I could swear that I tried print("Hello, World!") in the Firefox console once and it opened the print dialogue (useless because I wasn't connected to a printer in any way), but now it just returns the string... — ETHproductions, Commented Dec 31, 2016 at 1:54
@ETHproductions in chrome doing <script>print("Hello, World!")</script> does open the print dialog, but without the actual text on it. — FlipTack, Commented Dec 31, 2016 at 10:23

           In this case, "LPRINT" and a space

\$\begingroup\$ @eis Yes, I made QBIC. The link is a Google Drive folder with all the code in it - I suck at GitHub... It's an interpreter atop of QBasic (QBIC stands for Quick Basic's Interpreter for Codegolf) and it runs in DosBox.

\$\begingroup\$ The OP used a capital "W" to avoid builtin "hello world" (see also).: building your own builtin command for the job is not code golfing, or you could make it "0 bytes" with a builtin default behavior for that. \$\endgroup\$

\$\begingroup\$ @Cœur: that hardly works nowadays, most newer golfing languages use the capital W precisely because it's standard on PPCG, and it's highly likely that the command was added with no knowledge of this particular challenge (just a guess that more "Hello, World!" challenges would be submitted in the future) \$\endgroup\$

Batch, 22 bytes

echo Hello, World!>prn

This redirects the output of the echo command to the device file PRN, meaning that it's sent directly to the default printer (usually LPT1).

I neither have a DOS machine nor a printer, so I'm afraid I can't test this right now, but I'm fairly certain I've done this back in the day. It doesn't work on Windows XP or later.

MATLAB, 40 37 36 bytes

Printing text is not something you'd normally do in Matlab, but it can be done.

title 'Hello, World!'
axis off;print

I saved 3 bytes thanks to Tom Carpenter (use title instead of text(0,0,. I saved an additional 2 bytes by substiting title('Hello, World!') with title 'Hello, World!' followed by a newline instead of a semicolon.

title adds a title to a figure. If a figure is not yet open, it will be created.

axis off is used to get rid of the frame and axes, so that the text appears alone.

print prints the current figure to the default printer if no input arguments are given.

I printed this (successfully according to the dialog box) on my default printer at the office. I can retrieve it there and prove it but you'll have to wait two weeks. After changing the default to a pdf-printer, this is the output:

      }
      return i > NO_SUCH_PAGE ? 1 : PAGE_EXISTS;
    }
  });
  job.print();
}

Java is not a great golfing language, and certain does an exceptionally poor job golfing anything hardware-related, printing included.

While testing this program, I set my PDF printer as the default. It worked, but also sent a print job to my laser printer containing 87,792 pages of "Hello, World!" I pulled the paper tray and canceled the job, then retested. It did not happen again. Thanks, Windows 10.

\$\begingroup\$ If you're using multiple languages, you also need to count the glue that connects them together as part of your byte count. I'd count this as 15 for the Batch program, plus 0 due to the need for a 0-byte external file. \$\endgroup\$

APL (Dyalog), 50 bytes

Of course we could shell out and use a Batch/Bash solution, but let us instead create a real print job:

{'X.'⎕WC'Text' 'Hello, World!'⍵⊣'X'⎕WC'Printer'}⍳2

⎕WC is Windows Create object

First we create a printer object (a print job) called 'X', then (⊣) in that ('X.') we create a text object at ⍵ the argument of the anonymous function {…}. The argument is ⍳2, which gives the first two integers (1 2) and means 1% from the top and 2% from the left. When the anonymous function terminates, all its local variables (X) are destroyed, which signals to Windows that the print job is ready to be printed:

I used the win32api library to do this.

import win32api;open('h.txt', 'w').write('Hello, World!');win32api.ShellExecute(0, 'print', 'h.txt', None, '.', 0)

HP‑41C series, 44 Bytes

Because this program uses accumulated printer output (ACA), the printer’s print mode must be set to man (manual). In trace or norm (normal) mode the print buffer is printed prematuraly, thus not producing the desired result. This preparation cannot be programmed.

01♦LBL⸆P           5 Bytes    global label requires 4 + n Bytes
02 ⸆H              2 Bytes    set alpha register to the string "H"
03 ACA             2 Bytes    accumulate alpha register contents
04 ⸆ELLO,          6 Bytes    overwrite alpha register again
05 SF 13           2 Bytes    sets lower case flag
06 ACA             2 Bytes    accumulate α‑register and translate to lowercase
07 ⸆ W             3 Bytes
08 CF 13           2 Bytes    disable lowercase translation
09 ACA             2 Bytes
10 ⸆ORLD           5 Bytes    exclamation point cannot be entered via keyboard
11 33              2 Bytes    put character code for `!` into `X` register
12 XTOA            2 Bytes    append character identified by `X` to α‑register
13 SF 13           2 Bytes
14 ACA             2 Bytes
15 PRBUF           2 Bytes    print contents of printer buffer and clear it
16 END             3 Bytes

−1 B: You can use the command ADV (1 Byte) instead of PRBUF (2 Bytes). The print buffer procedure starts printing from the left‑hand margin. The advance procedure prints the buffer right justified.

−2 B: The END command allows inspecting the program’s size via catalog 1 and forms a barrier for local label search. A RTN (1 Byte) does not have said characteristics.

Let’s see the program in action: Note, the video actually shows a program with a couple ADV inserted before the END.
_{PS: Yeehaw! This is my 100^th (programming challenge answer) post!}

\$\begingroup\$ Is there a reason the tag has to be <svg> specifically, or would any tag work? (Many tags have shorter names.) \$\endgroup\$

\$\begingroup\$ afaik, only svg, img (with a valid src), iframe and body have an onload event triggered when the page is loaded. img without src triggers an onerror event. all in all, the shortest we've found is svg onload=... \$\endgroup\$

\$\begingroup\$ The challenge asks for upper case W (not that it changes your byte count). \$\endgroup\$
