[nitpick]Laser printers do not print with ink! They apply a static charge to the paper, which attracts toner to it. The toner is then fused (ie high heat is applied, and the toner melts), which gives the effect of a printed letter on the paper. Hence why the “ink” doesn’t run or rub off, and also why the paper feels warm when it comes fresh out of the printer.[/nitpick]
To answer the question - MOST bubblejet/inkjet printers will have some level of suckage. As others have already pointed out, the biggest problem with inkjets is to do with ink quality and print head quality. Left unused, a printer’s print head will dry out, leaving nozzles clogged. End result is a line through the print, crooked print or fuzziness in the print quality.
The Canon S300 series (and the 600) were the bane of my fucking existence. Print heads, print heads and print heads. And when the print heads actually worked, the paper feed mechanism would usually have some problem or another. Misfeeds, multiple feeds, non-feeding were commonplace. The issue there (IMHO) was an overly-complicated feeding mechanism.
Print quality problems (in inkjets) are further exacerbated by using non-genuine ink. Yes, I know it’s a ripoff. But the fact remains that the genuine product usually doesn’t fuck up quite as badly as the knockoffs. Additionally, if you have problems with the head and it is found that you have used non-genuine ink, there will be problems with any warranty claim you make on the consumables.
Speaking of consumables, consider that a printer in the $100-130 mark uses consumables that cost $80. That should tell you something about the cost (ie worth) of the printer itself.
With laser printers, you immediately bypass most of the suckiness associated with inkjet printers. Still, there are problems that are common to both (paper feed problems, jams), and problems that are specific to lasers (most commonly the fuser unit).
As much as it seems strange, I never had a great deal of Canon (or HP - most are built on Canon engines) lasers come back for repair. Of those that did, it was most often a paper feed problem - worn separator pads causing multiple pages to feed, or paper pickup rollers worn causing paper to stop halfway through.
If someone were to ask me what laser printer they should buy, I’d tell 'em an HP. As for inkjets… bah… they all suck (for reasons stated above).
Max.
