Can't ping a printer on the same subnet, why?

The Canon MF732 MFP
has a Wi-Fi printer on the local network, I ping from it 8.8.8.8 - everything is ok, I ping it from the laptop - Destination Host Unreachable, I ping my laptop from it - Destination Host Unreachable. The printer is connected to the wifi, the settings have been received - IP-address, mask, gateway, everything is there. Where to dig?
the printer is connected to the same WiFi as my laptop, there are no guest networks, there are no vlans either
IPs from the same subnet: 10.0.1.12 - printer, 10.0.1.158 - laptop, mask = 255.255.252.0
the firewall on the printer is disabled, all clients connect via wifi, there are no other complaints about the network,
in a stupor I
did a factory reset, he again received the settings from the router - the same app, but the picture is the same - ping does not
work apr -a gives this (I do it from ubuntu):
? (10.0.1.12) at incomplete on wlp2s0
tried:
arp -s 10.0.1.12 mac printer
got:
arp: invalid hardware address
printer:
ip=10.0.1.12
mask=255.255.252.0
gateway=10.0.0.254

norebook:
ip=10.0 .1.158
mask=255.255.252.0
gateway=10.0.0.254

ipv6 disabled

look at the routing, most likely something with it, because the equipment where the printer is connected via wifi does not let it into the local network, but only gives the Internet, as if it is included in the DMZ.

You have some kind of hellish addressing, usually the gateway is assigned the first address on the network, your network address is 10.0.0.0/22, the
first address of the host (gateway) is 10.0.0.1/22, broadcast 10.0.3.255/22
Show routes on the gateway
