Printers Randomly Disconnecting
Hello all, I work for a company in a fairly large building (1200 ish users, 2500+ devices) that happens to have a restaurant at one end. They have Toast and everything has gone smooth for for the last 8 or so months, until last Tuesday when the 4 printers we have randomly disconnect or wont reconnect at all. I have tested all the devices including connecting via web interface and can test print from there, but the two POS systems with direct connections cant seem to find their own respective printers.
We are not using Toasts hardware for networking we are self managed using Aruba switches and access points. The restaurant has its own Toast SSID that isn't shared anywhere else in the building, and all the printers are hardwired. Two in the kitchen and two at POS stations. If i reboot the POS systems or handhelds sometimes they reconnect and can print fine, whereas other times they randomly disconnect or have no connectivity to the printers at all. All devices can connect to the internet or the Toast SSID without issue. All of the printers can be pinged without any connection drop. All the ports are new runs within the last year using Cat6A, that test fine.
Toast support tells me they work better with "dumb" switches and that our network may be too complex. Yes, that was their response. I ask, "Well it was working for eight months until a week ago, what changed?" We are thinking of creating a separate VLAN for toast with like a 20 or so IP range, as it is currently DHCP with a bigger pool, but again was working fine. I had statically set many of the devices to the exact same subnet today for testing, as some had some variance (but were still randomly connecting, and worked prior) but that didn't change anything, and the connection issues remained.
Any suggestions? We are looking into a new VLAN or even trying some unmanaged switches prior to hitting our network, but I genuinely have run out of ideas at this point.
