Health › checks. Pick Printer installed. The agent looks for the printer by name. You are still pushing a document, not a script.
Open the Windows machine, then health › checks. The primitive is Printer installed. The name is the printer as Windows lists it. On Reception PC that is Reception. An hour is enough; a printer does not come and go every minute. Add a disk or ping check is the same editor.
Press add to list. The check sits in the document. Push to agent is the next click, and it asks you to confirm. Push replaces the whole document. This shot stops before that, so nothing has been sent. When that printer is not installed, the alert is a check failure.
Push is a two-step button. The agent must be online to evaluate. You can still add the check while it is offline, and it applies at the next hello. A mapped drive is Check that a drive is mapped. Free space is the same editor.
