im not sure about the signjet robin.
most printers are usless for outdoor work unless they are laminated.
even at that , they only last about 6-10 month.
we are thinking on buying a wide format printer.
the best one ive seen is the graphtec. its also a print & cut.
prints about 62" wide i think.
if you need more details on it, you can get them form brian hays.
brian works for impact sign services & they can supply the machine.
i guess you could ask him about the signjet also. he may know somthing about it. 🙄
