2. Dots per inch - Wikipedia

   en.wikipedia.org/wiki/Dots_per_inch

   Dots per inch. A close-up of the dots produced by an inkjet printer at draft quality. Actual size is approximately 1⁄4 by 1⁄4 inch (6 by 6 mm). Individual coloured droplets of ink are visible; this sample is about 150 DPI. Dots per inch (DPI, or dpi[1]) is a measure of spatial printing, video or image scanner dot density, in particular the ...

3. HP LaserJet - Wikipedia

   en.wikipedia.org/wiki/HP_LaserJet

   In September 2001 HP entered the low-end laser printer market with the introduction of the LaserJet 1000: the first sub-$250 LaserJet and the lowest-priced monochrome (black and white) LaserJet printer to date. It offered 10 ppm, an HP Instant-on fuser, 600 dpi with HP REt boosting output effectively to 1200 dpi, a 2.5-cent cost per page, and a ...

4. Pixel density - Wikipedia

   en.wikipedia.org/wiki/Pixel_density

   Scanners and cameras. "PPI" or "pixel density" may also describe image scanner resolution. In this context, PPI is synonymous with samples per inch. In digital photography, pixel density is the number of pixels divided by the area of the sensor. A typical DSLR, circa 2013, has 1–6.2 MP/cm 2; a typical compact has 20–70 MP/cm 2.

5. Dot matrix printing - Wikipedia

   en.wikipedia.org/wiki/Dot_matrix_printing

   Dot matrix printing. Dot matrix printing, [1] sometimes called impact matrix printing, is a computer printing process in which ink is applied to a surface using a relatively low-resolution dot matrix for layout. Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires [2][3] and typically use a print ...

   doPDF is a Portable Document Format (PDF) printer developed by Softland, that allows any program that can print to create a PDF file. The resolution of the created PDF files can be set manually or done automatically. [4][5] doPDF is freeware which displays advertisements.

7. Raster graphics - Wikipedia

   en.wikipedia.org/wiki/Raster_graphics

   Typically, a resolution of 150 to 300 PPI works well for 4-color process printing. However, for printing technologies that perform color mixing through dithering rather than through overprinting (virtually all home/office inkjet and laser printers), printer DPI and image PPI have a very different meaning, and this can be misleading.
