This is a quick rough guide on how to print your workspace as a PDF. This should be a standard feature of FME, but it is not. Printing off a workbench is very useful when creating documentation about workbenches. I am surprised at the lengths I had to go to for this. 


Step 1:
Follow this, or any other guide, on how to set up CUSTOM Paper Size for PDFs

I recommend adding size:
 

*Option: CUSTOMSIZE
{
*rcNameID: =USER_DEFINED_SIZE_DISPLAY
*MinSize: PAIR(936000, 1332000)
*MaxSize: PAIR(109728000, 164592000)
*MaxPrintableWidth: 109728000
}

Then, printing the item requires another bit of jankyness to make this work:
 

1. 

   click landscape
2. make sure there is only 1 page
3. press fit to scree
4. now it looks “ok” to print, but it isnt yet. hit the print button (mine is missing for some reason)

5. select print to pdf
6. hit preferences
7. hit advanced 
8. choose your newly defined page size
9. hit apply
10. DO NOT PRINT YET. exit the window.

Finally, hit the fit to page once again (step 3)
Now, hit print again, and print your item to pdf.

You now have a READABLE (wow) PDF of your workbench! Yes it is huge, but it works!
