Ok, here is the deal. I have network printer/scanner. Long time. This is Dell 1815dn
On Windows PC I install driver and setup "scanner" access to this printer. Then, on printer I can scan to "Network", it finds PC and places scanned document into proper folder on PC.
Why Mikrotik? Well. All this was working before I installed Mikrotik router.
What happens now is. If I re-set driver/printer on PC - I can go in and scan into PC from printer no problem. But after some time printer "stops seeing" this PC. I have to re-initiate setup from PC side in order to scan.
Any pointers or ideas on why this might be happening?
