=={{header|Commodore BASIC}}==

Most Commodore printer peripherals operate off the IEC bus commonly as device 4 or 5. It is also possible that some printers may be connected through the RS-232 serial port (typically device 2). This example assumes a device on the IEC bus with a default setting of device 4. This example does not utilize any printer control codes to change font, pitch, quality, graphics, etc., as those can vary between brands and models of printer.

EchoLisp supports a virtual printer which is not stdout. It is actually an extensible division of the HTML document, with printer pages as subdivisions. Printer and pages may be hidden/shown at convenience.

=={{header|EDSAC order code}}==

This program uses self-modifying code to loop through an array of characters. Since the EDSAC character set does not include lower-case letters or exclamation marks, we actually print <tt>HELLO WORLD</tt> followed by a carriage return and a line feed. Strings cannot be null-terminated, because 0 happens to be the character code for <tt>P</tt>; instead, we mark the final character by including a 1 (which has no printable effect) in the least significant bit.

===========

&D [ Line feed + 1 ]

==={{header|Alternative}}===

The EDSAC PC simulator allows .F for null and *F for letter shift, but it seems from WWG that on the original EDSAC these had to be input as K4096F and K2048F respectively.

=={{header|Forth}}==

Forth systems currently run on everything from bare metal to modern multi-user operating systems and printers are handled differently on each. This demonstration shows a common way that text output is re-directed to printers and/or other devices by vectoring the action of the Forth word EMIT. Emit takes one character off the stack and outputs it to a device. By defining all I/O with the primitive operation EMIT, we can vector the output anywhere we choose, even on hardware with no O/S. Here we show a very basic printer device driver for an embedded system that adds I/O re-direction to the system's Forth language.

defer emit \ deferred words in Forth are a place holder for an

\ vector control words

: >console ['] console-emit is EMIT ; \ assign the execution token of console-emit to EMIT

Usage Examples:

Since for a new job, output would commence with the lineprinter already at the top of a new page, an overprint (no carriage advance) thus means writing to the very first line. If however, top-of-page placement was not assured at your installation, then "1HELLO WORLD!" would do.

We can use printer like a page printer

Printer {

\\ just change the current layer to Print Page

Print "Hello World!"

}

Or we can use ANSI output using a file for export in Lpt1

Try ok {

Open "Lpt1" For OutPut As N '' prints to Lpt1 if exist a printer

}

If Not Ok Then Print "Can't Print"

If we have a file in current dir we can use a Dos command:

Dos "Print /d:lpt1 file " +quote$(dir$+"this.txt");

Using ; at the end of DOS command we have no open terminal

You can associate the variable "print" with lpt1 (the default local printer port) using the output() function:
