Skrivare Hewlett Packard DeskJet (en vintage skrivare)

Detta var den första bläckstråleskrivaren. Manualen är tryckt 1988. En HP DeskJet Professional printer med manualer. Helt fantastisk på sin tid. Jag har kört dess selftest, och det fungerade. Men inte kört den mot någon dator, ty då måste man ju fixa drivrutiner. Name: DeskJet Product Number: 2276A Så här skriver HP på sin sida http://hpmuseum.net/display_item.php?hw=304 The HP DeskJet was a major breakthrough in inkjet printing. The lab name for the original 300dpi inkjet printer was "Voodoo". It printed on plain paper and offered "laser quality" (300dpi) output. Best of all it was priced at less than half the cost of a laser printer. The DeskJet was a hit; it was the next best thing to a personal laser printer. The DeskJet did have its limitations: its print quality was "fuzzy" when compared to a laser printer, it was big, and the ink was not waterfast - it was easily smeared with moisture (eg highlighting pen, coffee cup). It was also expensive to run when compared to an impact printer. The DeskJet proved the importance of print quality among low-end printer users. The industrial design (boxy look) of the original DeskJet was to be used for follow on products over the next 6 years (DJ Plus, DJ 500, DJ 500C, DJ550C). The DeskJet brought a big jump in inkjet printer sales, but bigger jumps were yet to come.

Customers knew its predecessor, the HP ThinkJet, because HP had been first to market with the inkjet printer, but HP wanted to refine the technology and produce a better product. The name DeskJet was introduced to draw a clear distinction from the preceding inkjet printers HP had sold. The DeskJet offered continuous plain-paper printing and higher print quality than its inkjet predecessors. At about $1,000, it was the least expensive non-impact printer on the market at the time it was introduced. However, HP wanted to bring the price down even more. By 1993, when HP had achieved enough sales volume to employ economies of scale, the list price was $365. Customers could now get a printer that was superior in every way to an impact printer (such as a dot-matrix printer or daisy wheel printer) for the same price. And by 1994, the DeskJet offered a color printing upgrade, creating single-handedly a revolution in color printing. Perhaps the most significant technological achievement in the early days of HP's DeskJet printer was the creation of a very inexpensive, disposable print head that could be built into the ink cartridge itself. The value and efficiency of a disposable print head is in its ability to guarantee a consistently high level of print quality over the entire life of the printer. Competitors offered permanent print heads, which tended to clog and need replacement. The DeskJet developed into HP's current Deskjet, Photosmart and Professional Series printer lines, all of which are based on thermal inkjet technology.
