I'll be happy to provide any assistance that I can. Feedback for each of your inquiries is provided below:
Choosing a printer modelBoth types of printers (inkjet and laser) would be suitable for this type of application. Laser printers provide more durable printing results by nature. You definitely wouldn't need to use a protective overcoat spray with weatherproof laser labels. You likely wouldn't need an overcoat spray with weatherproof inkjet labels, but some customers choose to use the spray with inkjet labels to protect against any possible contact with oils or chemicals that could potentially cause the labels to smear or smudge.
I've personally had an opportunity to use the Canon PIXMA series of inkjet printers as well as the HP LaserJet series of laser printers. Both are excellent printers and should work very well with your application. If you do decide to go with an inkjet printer, I think you'd definitely be safe to go with the MX922 as an entry point into printing your labels. I've used a very similar printer model in the PIXMA series and have always been very pleased with the results.
