ls /dev/cu*
In my instance the USB adapter was /dev/cu.usbmodem14101
Then run:
screen /dev/cu.usbmodem14101 115200
Where 115200 is the baud rate.
Et voila, you can see what the printer is doing.

Here’s how to add a new product in Woocommerce.
On the Dashboard, on the left hand side, hover over Products and click on Add New:
Fill out the Product Name at the top and then write a description in the white box below:
Scroll down:
Make sure you fill out the Regular Price and select a category on the right hand side.
Once you have done that, click on the Inventory tab on the left to mark it as being in stock or out of stock. Then click on Shipping, fill out the weight and dimensions, then select a shipping class. The latter dictates the shipping rates.
Once you have done that, on the lower right select “Set Product Image”;
From there, drag and drop your desired product image into the screen and it’ll upload it. Once that is done, click on the blue button in the lower right hand corner to set the product image.
This is just one image and it’ll be the main product image – if you want to have a gallery of images you can set that after you set the individual product image. Once back on the main product page, select Add Product Gallery Images to add multiple images.
Once you have done all that, scroll back up and hit Publish – blue button on the right hand side – and the product will be live.
I can’t stand the new Photos app – I just want a grid back! Here’s how to get it back to the way it was.
In the Photos app, click on “All Photos” in the lower right.
Once you’re there – and it should look a bit closer to the old app now – click on the +/- in the top right hand side.
Hit – to increase the number of photos on your screen at once, and + to decrease it.
By doing this you can put it back pretty close to how it was – much more useful for rapidly skimming through photos, in my opinion. The new update may have made it prettier but it made it less useful in the process for those who need to skim back through hundreds or thousands of photos to find one specific shot.

/etc/php/7.0/fpm/conf.d/…but had not been enabled in this directory also:
/etc/php/7.0/cli/conf.d/…which is another directory that needs the same config file in. In my server’s case the config file was named 00-ioncube.ini and consisted of the following:
And with that, voila, cron job works. Can’t get that hour of my life back, though. Update: For the php7.1 servers the zend_extension line read:zend_extension = “/usr/lib/php/20151012/ioncube_loader_lin_7.0.so”
zend_extension = “/usr/lib/php/20160303/ioncube_loader_lin_7.1.so”
Sorry, this product is unavailable. Please choose a different combination.Very frustrating. The problem in the end? I had not yet set prices for all of the variable products. To resolve this go to Product -> Variations -> click on the dropdown box which defaults to “Add Variation” -> Set Regular Prices -> click Go. Hopefully that’s all it takes to fix your problem too. I was installing custom PHP snippets to try and resolve this issue and going down all sorts of wrong paths when I had simply neglected to take note of which fields were required.
