PlayOnLinux is a front-end for Wine. Wine actually uses CUPS to print. You might need to configure CUPS for your printer of choice so you can print from your Wine applications.
First, make sure CUPS is installed:
sudo apt install cups
After CUPS is installed, you can access the CUPS admin page from a web browser by accessing the following address:
http://127.0.0.1:631
Check the printers tab to see if any printer has been added:

If you have a printer, then you should be good to print. If not, add one by clicking on the Administration tab. Then click on the Add Printer button:

Next, it should come up and show you all printers on your system. Click the printer you want to use:

Click continue. It should be now showing you the information about your printer.

If it all looks good, click continue again. Now you get more information.

If that looks good, now click Add Printer button. It should bring you to the default settings.

Click Set Default Options. Now your printer should be added.

You will need to close all Wine apps first. Now, in your Office 2007 apps, when you print you should now see the printer to print to.

Hope this helps!
