Quality of printing: InkJet vs laser.
Laser printers do an excellent job of letters, especially if they have PostScript capability InkJet printers
may fail to avoid jaggies (stairstep outlines of text or line art) To get an inkjet do produce letters without jaggies requires using Adobe PostScript interpreter This implies buying a RIP software RIP software includes more Adobe or an emulator A RIP for a wide format inkjet printer costs about $2.500 often the software costs more than the printer!
Most of the better laser printers have Adobe PostScript built into them (which is why a laser printer costs more than a cheap inkjet, since the inkjet has inadequate software) Now some printers are adding Raster Image Processor software too.
The top models of QMS and Tektronix do a good job of reproducing photographs if your original photograph itself is of professional quality Office laser printers such as Lexmark and HP do okay with photos (HP is better nowadays) In desktop inkjet printers. Epson and Canon produces outstanding quality but most of the images fade quickly Lexmark and HP are more for business printing on average paper such as pie charts and bar charts Downside is lack of longevity. In that respect laser is still better.
Ink cost: InkJet vs laser.
A laser printer will cost more to buy the machine, but paper and toner costs are reasonable An inkjet
printer is priced very cheaply in order to ensnare you into being stuck buying their overpriced ink. With an inkjet printer the cost of ink and media can mount up rather quickly.
Toner cost for a laser printer is much less costly than ink cost for inkjet.
Making lots of copies: inkjet vs laser.
If you tried to print 100 copies of anything on any inkjet printer you would quickly understand why an inkjet is totally inappropriate. They are just too slow to print multiple copies.
Inkjet printers are deliberately cheap, the inkjet companies want to give you the printer as close to free as possible so they can then sell you overpriced ink and paper. A single sheet of paper plus ink costs about $1 a sheet Your printing costs may quickly exceed your rent or your car payments (and then the prints fade). Some Epson inkjets can't do black-and-white (they look green).
Variability among prints: inkjet vs laser.
With an inkjet printer you will tend to get all the prints more or less the same color as long as you stick
with one single kind of paper Not precisely identical color but similar In terms of color consistency the same image, on the same printer on two difference days. Inkjet will not always be identical color from day to day, but laser color may be off even more. Where you really get severe color differences is switching from one paper to another brand on the same inkjet printer Since each paper mill uses different chemicals on their inkjet coatings, the ink reacts differently. It takes color management tools and software to calibrate the printer & ink. if you print many copies, or print some first and then re-submit and print more another day, the colors may vary So precise color matching is not yet perfected on most desktop laser printers However the newer printers being released this year do have improvements in hardware and software trying to overcome these well known deficiencies.
If you have one of the few laser printers which can accept RIP software, then you can control your colors better. As mentioned above, this implies that you learn color management.
