Re: I know the series well...
The 4L was a very nice machine but incredibly slow by today's standards / 4 pages per minute. That's around 1920 in a working day.
You can buy a decent 45 page per minute nono printer now for around £500 that will do that in less than an hour. As an example Ricoh 4520 (with LCD touch screen, PS, PCL5c, PCL6, duplex, USB2 and ethernet) that I have a lot of in the field that have done over 300'000 prints each in 3 years (some of them in appalling conditions / convered in metal filings, dust, random chemicals and in one case an aircon failure soaked one and they all refuse to die much to the disappointment of my sales dept lol).
Anyway, the point is I would love to see the max volume someone has got out of a HP laserjet 4L just for giggles and also to see if they really do 'make them like they used to' :)
