The main difference between the two sets of printer control characters might be the portability of ASA control characters versus the hardware dependency of machine control characters. The fact that the ASA controls were space before write , while the machine controls were space after write could require some data streams to be converted.
ASA control characters are simple printing command characters used to control the movement of paper through line printers. These commands are presented as special characters in the first column of each text line to be printed, and affect how the paper is advanced before the line is printed. The remainder of the line is printed starting in the ...
Printing control characters were first used to control the physical mechanism of printers, the earliest output device. An early example of this idea was the use of Figures (FIGS) and Letters (LTRS) in Baudot code to shift between two code pages. A later, but still early, example was the out-of-band ASA carriage control characters. Later ...
In 1973, ECMA-35 and ISO 2022 [18] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [19] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [21] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
Form feed is a page-breaking ASCII control character. It directs the printer to eject the current page and to continue printing at the top of another. Often, it will also cause a carriage return. The form feed character code is defined as 12 (0xC in hexadecimal), and may be represented as Ctrl+L or ^L.

Note that the printer itself is not necessary to be wireless. AirPrint is a feature in Apple Inc.'s macOS and iOS operating systems for printing via a wireless LAN (Wi-Fi), [5] [6] either directly to AirPrint-compatible printers, or to non-compatible shared printers by way of a computer running Microsoft Windows, Linux, [7] or macOS.
Unicode does not give names to control characters but has assigned it the alias "ALERT" and abbreviation "BEL." It can sometimes be typed as ctrl+G and displayed as ^G in caret notation. Unicode also includes characters for the visual representation of the character: U+2407 ␇ SYMBOL FOR BELL and U+237E ⍾ BELL SYMBOL.
