Your talking crap the only place I have seen Konica Minolta being used in the schools are in the admin department. Most classrooms use laser printers their cheaper to run end of! and maybe next time you get your head checked at the local hospital pay attention and you'll find a large proportion of the printers they are using are HP laser printers.
You've definitely paid attention to printers. A popular brand they use is Konica Minolta printers which are inkjets. A laserjet produces heat and gases which cannot be used. Clearly you have not seen or used one of those printers. The printers on hotukdeals are home printers which are not suitable for high volume printing. High end inkjets are quite fast and your reasoning is not necessarily true for places like them. So your assumption is bs as you have not seen any
What a load of rubbish their is no way inkjet would be economical for schools, office or hospital. All three mainly print in mono and in large quantities hence their preferred choice is Laser. Schools may be tempted to use a colour inkjet ecotank in an Art department where colour laser printers are usually expensive to run but for everyday use they will always go for laser printers as the costs are more economical and they can cope with the demand put on them. Another reason schools are less likely to go for inkjet as well is the summer holidays where printers would not be used for 6 weeks possibly leading to clogging.
Can't see schools using inkjet too slow and not economical enough for them. When I was in 6th Form (joined onto a large secondary with 1500 students) they had about 25 laser prints through out the school mainly Mono ones due to cheap running costs that was back in 2011, I cant see much changing since then. Could see the colour ecotank printers possibly being cost effective in a schools Art department though as I remember the colour laser printers back then costing a fortune to run.
Yeah our printer in work is laser a3 and costs leas than half a penny per page. This is more for home users surely.
