We have a black and white laser printer and we use it 99% of the time. After all, as a writer, people want your words, and your words are the same in black and white or color. For the 1% of the time we need color, we have a nice color, networked, INKJET printer that prints great quality and we are very satisfied with for everything from samples, to fliers, to signs, to pictures for my daughter to play with.
So, when we decided to help out our client, we gleefully printed around 83 extra newsletters. It took a long time, but we just did other things while the printer worked away. The next day, we folded, stuffed envelopes, and dropped 83 newsletters in the mail. Then, a few days later, we got the phone call.
You see, inkjet printers are "wet" printers. The inks must dry. That is why we waited overnight. But, there is a catch, 83 six page newsletters makes a stack of 249 double sided pages. The ink doesn't dry very well, even overnight, on printouts 2 through 249. So, when we folded, they smeared. When we mailed, the ink transferred across the folds to the facing area of the page. When they opened, they were a mess.
In the past, we've never printed so many pages at once, so we laid them out on the table or counter to let them dry. That isn't practical with so many pages, so the answer is LASER. So, now that we need laser, we meet all of the above criteria.
