However, claiming Linux can't print due to a particular printer not supporting Linux is pretty much the same argument as the Pi is not a real desktop, since Microsoft will not release version of Skype for it.
Which is exactly why I included (not the Pis fault) in my comment.
Just as the problem of Linux not being able to print was not the fault of Linux. In the 90s when we converted all our business operations to Linux, and many of our customers' operations, we always had to have a Windows computer to serve the printers. That continued well into the 2000s.
I am not changing all my printers to a brand which will print with the Pi.
But eventually, as they did with Linux, printer manufacturers will begin to realise that there are lots of these little Raspberry Pi things finding their way into homes, and hey, it just might be a sneaky marketing move to port or write a suitable driver.
For now, though, I have the Brix sitting a little over a metre away on the same work bench, connected to one of the printers via WiFi.
Which is why the poor old Brix is rarely turned on now...
I always have to laugh when people use boot time as a benefit of using a Pi, since the Pi really doesn't boot all that fast. Sure it's easy to find examples of computers that boot less quickly, but it's just as easy to find ones that boot faster.
Just as I do not see any reason to change my printers to suit the Pi, I have no intention of trying to buy a faster booting computer when I have half a dozen perfectly serviceable machines still lying around left over after retiring from my business interests.
Pi 4 is booting in about 20 seconds on microSD/SSD, Manjaro in a little less on plain microSD. Either is pretty well perfect, and for the most part both are loading programs faster than the older, though supposedly more powerful computers, some of which cost thousands of dollars.
They all boot slower than the Pi, mostly because they ran KDE , now updated to Plasma 5, and one runs XFCE again.
If I installed Plasma on the Pi 4 I might manage to get it to run more slowly than the Pi 4, but why bother?
I'm rather pleased with my little 'not a real PC' that doesn't have Skype..
