Dot matrix printers, also known as impact matrix devices, are an older kind of printer that relies on an ink-soaked ribbon similar to that used in a typewriter. These devices were the most common ...

While laser and inkjet printers are increasingly popular, older technology still has value in daily life. Dot matrix printers are similar to manual typewriters, with a history dating back over 100 ...

A recent paper set the fastest record for multiplying two matrices. But it also marks the end of the line for a method researchers have relied on for decades to make improvements. For computer ...

Before the 1980s, laser printers were expensive, high-volume units. At that time, dot matrix printers commanded the early PC desktop market for homes and businesses. Compact laser printers, introduced ...

The LA36 was the first widely successful dot matrix printer and made printing faster and more efficient during an age when paper ruled the office world. Given that so many documents can now be stored ...

Computer scientists have discovered a new way to multiply large matrices faster than ever before by eliminating a previously unknown inefficiency, reports Quanta Magazine. This could eventually ...

Don't let a malfunctioning dot matrix printer give you fits. Learn some techniques for solving several common dot matrix printer problems and advice on finding increasingly scarce parts. These days, ...

Mathematicians love a good puzzle. Even something as abstract as multiplying matrices (two-dimensional tables of numbers) can feel like a game when you try to find the most efficient way to do it.

In this video from PASC17, Alfio Lazzaro (University of Zurich, Switzerland) presents: Increasing Efficiency of Sparse Matrix-Matrix Multiplication. “Matrix-matrix multiplication is a basic operation ...
