Printer

A Reliable and durable printer sought that can imprint a lot of papers with as less ink as possible. – say 3,000-5,000 pages in one go, 500 times with one inkjet or so. Also:

1) What kind of printers use heat/laser as ink, imprints on a special/non-special kind of paper? And, how much is it (both)?

To clarify 86's comment, the OP's specifications are appropriate for a serious commercial printing establishment, not for a SOHO environment. This is Canon's range of printers for those sort of volumes - other suppliers are available. But we are talking printers that cost about as much as a typical car.

See what toner is. The plastic dust gets molten onto paper. Todays multi function office machines, not at the SOHO entry level might already fulfill this need as dedicated printer or copier. One manufacturer owns a patend for automatic switching feed paper from next drawers. Large volume drawers with electric lift for feeding paper from top can load usually 2,000 to 3,000 sheet at once. This expensive machines make 25 to 80 prints per minute. But thats not the price and performance limit. --Hans Haase (有问题吗) 06:22, 15 July 2016 (UTC)

You didn't specify a high-quality print, or color, so maybe you might consider a line printer. One form is like a dot-matrix printer that prints a line at a time instead of a character at a time. They use very little ink, since they don't make solid letters, but only dots. They are not an appropriate choice for for pictures.

If quality is important, then a laser printer would be the best choice. A black-and-white laser printer is far cheaper than color, so choose that option if you don't need color. They aren't as fast as line printers, though, so you would likely need several. StuRat (talk) 14:08, 19 July 2016 (UTC)

Password-protecting SD cards

I bought an SD card for the sole purpose of tearing it down. But, instead of doing that, I want to know if I can play around with the password protection, temporary write protection, and permanent write protection mechanisms of it using a standard computer SD card port. I've read that most reader hardware does not have the capability to use these commands. Is this true? — Melab±1 ☎ 23:40, 14 July 2016 (UTC)

Have you checked whether the Secure Digital article, or the resources it links to, answer your questions? --71.110.8.102 (talk) 02:35, 15 July 2016 (UTC)
