From my experience I've had to deal with their software adware for which I've had to close pop ups and upsell ads before I could do anything with their printers, so that might be why it takes long to print a simple page
My issue lies elsewhere, it takes me that long to have the printer recognized by the OS, then by CUPS browser, then I send the printing job and... it just stalls, never prints. I then cycle the USB ports and start all over again until it miraculously prints
I have the exact opposite experience. It always prints and although it only prints about 6 pages per minute, it starts immediately. However, I have an old-ish HP laser printer without the crappy adware.
