I am in the process of purchasing a HP Latex 115 and should be here in about 3 weeks. I have two separate jobs already lined up for printing and installing window perforated Vinyl on the outdoor windows for two businesses. They that want this to remain on the windows for 3-4 year period. Question 1 - Do you recommend laminating? Question 2 - Any recommendations for a window perf that works well with my printer? Thanks for your help.
