Bug Description

I observed on a Ubuntu box that Hatch as invoked via the Chrome extension did not automatically detect new printers added after Hatch was first started. I had to manually kill hatch as invoked by the extension, then reload the workstation printers page to see the new printer.

Discussion at https://stackoverflow.com/questions/38470568/javafx-doesnt-detect-changes-of-available-printers suggests that javafx.print.Print.getAllPrinters() may require the app to be restarted to pick up new printers; it also suggests that javax.print.PrintServiceLookup.lookupPrintServices() may be more dynamic.

On the other hand, I see that commit 6158abb2fbf1 removed use of javafx.print.PrintServiceLookup. Bill, do you remember why?

Hi Galen, I don't recall the reason for that change. At a glance, I'd guess the current approach simply requires less code.

BTW, I have confirmed that restarting Chrome causes Hatch to restart as well. I'm wondering if you tried that before having to manually kill Hatch?

Hmm, not all the way, just closing tabs that had invoked the
extension. I'll try restarting Chrome outright, although that (IMO)
just moves the issue to something that would have a documented
workaround.

I have confirmed on Windows that adding a new printer works when stopping Chrome, adding the printer, then restarting Chrome. Though stopping Chrome first is (almost certainly) not strictly necessary as long as it's restarted afterwards.
