Cannot connect to Network Printer across 2 subnets

Here's the setup done by the old another IT guy that left:

-- Office Location A --
PC A1:
ip addr: 192.168.0.50
subnet: 255.255.255.0
gateway: 192.168.0.1
dns: 192.168.0.1
can print, yes; physically connected to printer via USB

PC A2:
ip addr: 192.168.0.17
subnet: 255.255.255.0
gateway: 192.168.0.1
dns: 192.168.0.1
can print: yes
NETWORK PRINTER PRINTER:
ip addr: 192.168.0.8

-- Office Location B --
PC B1:
ip addr: 192.168.1.109
subnet: 255.255.255.0
gateway: 192.168.1.1
dns: 192.168.1.1
can print: NO (it used to work 5 days ago, and now it cannot even find the printer on the network)

The old IT person setup a network between Office Location A and Location B, and I have not changed anything to the network since I came on board.
How can I get the PC B1 at Office Location B to see the Network Printer that is located at Office Location A?
