Question: What foundation does the inventor of the first laser printer available to the mass market run?

Context paragraphs:
Tektronix Phaser 740: The Tektronix Phaser 740 was a series of color laser printers sold by Tektronix's printer division, now a part of Xerox.  The Phaser 740 is notable for being the industry's first true 1200×1200 dpi color laser printer.  The printer was available in several different configurations, from the 740L ($1499 MSRP, only black toner included) to the fully tricked out 740 Extended (128 MiB RAM, duplexing, hard drive, etc.).  The "plus" feature set was required for 1200×1200 color printing.  Standard features included 10baseT Ethernet, LPT connectivity, SCSI connectivity, an expansion port for other networking options, 133 MHz PowerPC CPU, and PostScript.  Network protocols included Telnet, FTP, AppSocket, IPP, HTTP, and AppleTalk.  One upgraded the lowest model to the Extended functionality by adding components.  A notable feature of this printer is its ability to accept PDF files directly, through FTP or Telnet.  The onboard computer would then process the PDF to PS and print it.  Phaser 740 series printers required little maintenance compared to other printers of the time.  The only consumables were toner, fuser, imaging drum, and transfer roller.

LaserWriter: The LaserWriter is a laser printer with built-in PostScript interpreter introduced by Apple Computer in 1985.  It was one of the first laser printers available to the mass market.  In combination with WYSIWYG publishing software like PageMaker, that operated on top of the graphical user interface of Macintosh computers, the LaserWriter was a key component at the beginning of the desktop publishing revolution.

Gas laser: A gas laser is a laser in which an electric current is discharged through a gas to produce coherent light.  The gas laser was the first continuous-light laser and the first laser to operate on the principle of converting electrical energy to a laser light output.  The first gas laser, the Helium–neon laser (HeNe), was co-invented by Iranian-American physicist Ali Javan and American physicist William R. Bennett, Jr. in 1960.  It produced a coherent light beam in the infrared region of the spectrum at 1.15 micrometres.

HP LaserJet 1012: The HP LaserJet 1012 is a low-end, monochrome laser printer from Hewlett-Packard that retails for US $199.99 and was designed as an inexpensive laser alternative to Inkjet printers for home and small office use.  It is capable of printing a maximum 15 pages per minute (although after many pages, the print speed slows down to prevent overheating, as the printer has no onboard fan) and has a 1200 dpi effective output (optical 600 dpi).

NeXT Laser Printer: The NeXT Laser Printer [NeXT PN N2000] was a 400 DPI PostScript laser printer, sold by NeXT from late 1988 (1988) to 1993 (1993) for the NeXTstation and NeXTcube workstations and manufactured by Canon Inc. It included an adjustable paper tray, which enabled it to print on several paper sizes including A4, letter-size, and those of legal and envelope varieties.  It was very similar to other printers based on the Canon SX engine, such as the Apple LaserWriter II series and HP LaserJet II/III, although those other printers only printed at 300x300 dpi.  Some parts (such as the toner cartridge and input paper tray) are interchangeable with the LaserJet II/III.

Market run: A market run or run on the market occurs when consumers increase purchasing of a particular product because they fear a shortage.  As a market run progresses, it generates its own momentum: as more people demand the item, the supply line becomes unable to keep up.  This causes a local shortage, which in turn encourages further hoarding.

Risograph: Risograph is a brand of digital duplicators manufactured by the Riso Kagaku Corporation, that are designed mainly for high-volume photocopying and printing.  It was released in Japan in August 1986.  It is sometimes called a digital duplicator or printer-duplicator, as newer models can be used as a network printer as well as a stand-alone duplicator.  When printing or copying many duplicates (generally more than 20) of the same content, it is typically far less expensive per page than a conventional photocopier, laser printer, or inkjet printer.

LED printer: An LED printer is a type of computer printer similar to laser printer.  LED technology uses a light-emitting diode array as a light source in the printhead instead of the laser used in laser printers and, more generally, in the xerography process.  The LED bar pulse-flashes across the entire page width and creates the image on the print drum or belt as it moves past.

Laser: A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.  The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation".  The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow.  A laser differs from other sources of light in that it emits light "coherently".  Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography.  Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers. Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum, i.e., they can emit a single color of light.  Temporal coherence can be used to produce pulses of light as short as a femtosecond.

Alan B. Oppenheimer: Alan B. Oppenheimer is the president and founder of Open Door Networks, Inc., creator of the mobile app Art Authority.  From 1983 to 1994, he worked for Apple, Inc.  where he helped design the AppleTalk network system for the original Macintosh computer.  He also played a key role in the production of the LaserWriter printer, AppleTalk Remote Access, AppleShare file server and the Apple Internet Router.  Alan is author of several books and runs the Alan and Priscilla Oppenheimer Foundation with his wife.
