In the world of business and personal communication, the printer has long been an unsung hero. From the early days when Z 100s came out and the printer was an outrageously loud impact type, people complained about the noise, but no one suggested removing the printer. We have come a very long way since then and the HP Color LaserJet 2840 printer using Q3961a cyan toner is a perfect example of that technological evolution.

The invention of the typewriter, the predecessor to the printer, was a revolution for the communication industry, as well as for all written communication. No longer was penmanship a critical need for success, the typewriter leveled the field and increased the speed and efficiency with which one could communicate in written form. The typewriter reigned as king of print for all forms of communication from businesses to news to entertainment for decades. Naturally it had its drawbacks, correction of errors was at first simple; start over. This was not very efficient for businesses and led to many more errors in print than we would tolerate now.

As technology continued, the demand for ever greater capabilities in the typewriter expanded. The natural result was the merging of software with the typewriter. These new pieces of equipment allowed for the review of the typed text before they were committed to paper, preventing the need to retype whole documents. This capability gradually increased from a few lines of text to whole pages. This evolutionary intermediate between typewriter and computer did not last very long as the cost for information systems decreased to the mass affordability range.

The next step did not take long as the impact dot matrix printer came into widespread use. At this point programs were becoming more sophisticated and more than a page or two could be electronically written. Then not only could one proofread the work, but more sophisticated programs could spell-check it for you. This greatly enhanced the overall ability to catch typographical errors, as well as simple misspellings.

Remaining hurdles for the printer included a better, more consistent paper handling mechanism, greater print quality, and increased speed. Initially, it was faster to print one copy and then use a copying machine for replicates, as these machines were much faster. Further, the development of software allowing for all manner of graphics and even photographic manipulation demanded printers that could handle much more than the printed word. Dot matrix printing was up to the challenge in a primal way, but the quality was poor. Still, the obvious direction of progress was to improve the printer, not replace it.

A new type of printer solved many of the impact printer’s problems; the inkjet and laser printers were significant improvements. The printer at this point crossed over from written correspondence to image production. It was now possible to get smooth printed characters and numbers, as well as every variety of images. Initially the print quality still lacked due to the easily smudged final document, but it was far better than the impact printer and as good as the typewriter for professionally produced documentation.

In time the speed of these laser and ink jet printers increased along with the quality of their output, even eliminating the smeared ink problems. As one would expect, the software continued to advance apace, each driving the other for greater quality. Spell checking software, the thesaurus, and grammar checking software made the information system the ideal way to produce documents with far better quality than before in far less time. This was the demise of the typewriter, so much so that it is rare to find one outside a display or movie set in older times.

The introduction of the color laser printer rounded out the features already available, and combined with software amazing products were produced.  Anyone could now produce professional grade presentations of any type at home or the office, printed by a quality machine. The speed of these machines is now simply amazing, and the costs have been reduced to an easily affordable accessory to the home information system. Even photographs and greeting cards can be professionally produced in one, with printers like the HP Color LaserJet 2840 with HP LaserJet 2840 laser toner. Only outsized print jobs require assistance outside the home.

The many features of the LaserJet 2840 printer toner cartridge don’t overwhelm what it does and does well; print amazing color and monochromatic images with HP Q3960a black laser toner cartridge. Re-ordering cartridge is easy and efficient when done via online vendors.
