The Pro-100 is primarily a photo printer, designed to print primarily on various sizes of photo paper. It is not a general purpose printer for printing text documents like letters, reports, or envelopes.
The PIXMA PRO-100 can print on certain types of envelopes.
What operating system is installed on your computer; Windows or Mac OS X?
Our Pro-100 printers will not feed A2 envelopes no matter how many times we try. Using custom settings/envelope setting, it doesn't matter. It pulls in the flap and envelope body separately in such a way as it destroys it.
I was wondering if you ever found a solution to crooked printing on your envelopes? I also had this problem and the Canon phone help line I called said it could be dust and to clean out the feed tray...which didn't work. The only solution I have found... which is a terrible one... is to use wasi tape and tape my envelope to a 8.5x11 paper and print it that way. This is a painful process though especially when you have over 200 envelopes to print like I normally do. I don't recommend it, but it does work if your on a tight deadline and cannot get your envelopes printed elsewhere.
I have also had problems with the colouring being dark. I only bought this printer this past November and did so because all the reviews from other stationery designers were positive but I'm considering selling it and purchasing a different brand.
Sorry I'm not much help but wanted to let you know you are not alone. Maybe Canon will have an alternative solution to dust...
