Probably a huge factor. Its just a pain in the ass to occasionally print something. In the 90s we actually printed a lot more stuff. We printed maps, letters to mail, forms to fill out. Everything that was typed for school would be printed and turned in. I would print excerpts from groliers to read later. I printed recipes for my parents. So printing cards etc made sense because the printer was so frequently in use. I actually printed a few things this Christmas and it was annoying, required multiple reboots of the printer, a paper jam and a new warning message.
Yeah I love my laser printer. Actually earlier this year I bought an ink tank printer because I've had to print a number of things in color and have been really pleased with that.
But it's very difficult to beat the cost of a laser printer, especially for infrequent prints.
I can get close to 15-20 cards for the price of the ink cartridges and that's not even touching the price of buying software to print cards.
