Script Summary: Automatically open PayPal invoice, print it, return to details page
This script will automatically take you from the Details page of a PayPal transaction to the Invoice page, and click the print button. Please note that unless you further modify Firefox, you will still have to click OK on the print confirmation pop-up.
You can turn off the print confirmation pop-up by adding a line to about:config for Firefox. If you have never modified the config, I suggest reading a couple of guides on how to alter it.
Just add the preference print.always_print_silent, Type Boolean, with a value of True. This will mean that whenever you tell something to print, it will immediately be sent to your printer without a confirmation. There are some disadvantages to this, but it's handy if you need to print 20 or more PayPal invoices at one shot.
Also, if you use the Firefox addon Snap Links Plus, you can select multiple links at a time in PayPal and batch print your invoices. I'll add a detailed guide to my site soon and link to it.
