How about adding a description of long edge vs short edge for people who don't know which to choose.

Antiquated Term

[edit]

The article reads that an antiquated term is not commonly used in the workplace. Does that refer to single sided printing or duplexing? I consider single/double sided printing to be fairly often used (not an appropriate linguistic measure, but still). 76.198.38.250 (talk) 00:49, 2 July 2013 (UTC)[reply]

Fast duplex printing

[edit]

Also known as "Fast two-sided printing". The article says "Higher volume printers may effectively have two print engines in a single device, and are able to print both sides of the paper in a single pass." This is called "double-engine duplex", see also HP: What is Duplex Printing and How Does a Printer Duplexer Work and Printer and Copier Specification Terminology Explained. There is another method for fast duplex printing with single-engine duplex: Let's say we want to print 4 pages on 2 sheets. First, we print page 1 on sheet 1. Then, we print page 3 on sheet 2, and at the same time, flip sheet 1 in the duplex path. Then, we print page 2 on sheet 1, and at the same time, flip sheet 2. Then, we print page 4 on sheet 2. So effectively, 2 consecutive sheets are interleaved for printing, doubling the print speed. This results in a continuous output of sheets, with (almost) the same pages-per-minute speed as simplex printing. The downside of this method is the higher mechanical complexity (lower monthly duty cycle), because we still need a page-flip like slow duplex. The upside of this method are cheaper and smaller printers. A rule of thumb: Slow duplex is about 2 times slower than simplex, in terms of pages-per-minute. Known printers with this "interleaved duplex printing" feature: HP LaserJet 400 and 500 series with JetIntelligence (downside: expensive toner with chip), Konica Minolta Bizhub 4700P: Print speed Up to 47 ppm (A4), Autoduplex speed Up to 40 ppm (A4) = 15% slower than simplex (downside: expensive toner). See also: HP: The new HP LaserJet 400 and 500 series with JetIntelligence has the fastest two-sided printing in class and Canon: Fast Duplex Printing and HP LaserJet 200 series printers and Keypoint Intelligence: HP LaserJet M200 Printers and MFPs: Fastest Two-Sided (Duplex) In-Class. TODO: find websites that compare simplex and duplex printing speeds (and printing costs) of laser printers. websites like geizhals.de show only the simplex printing speed. TODO: how does duplex printing work in high-end digital printers? like Konica Minolta Bizhub Press 1250. probably they use "double-engine duplex". Milahu (talk) 15:03, 13 July 2023 (UTC)[reply]
