Update 6/15/2022: I bought the Epson ET-8550 and can report that it handles 300# cold press watercolor paper (1.2mm thick) without problems.
I’ve done a number of house portraits that way using 9″ X 12″, 300 gsm/140lb, watercolor paper, usually from a block or pad, but sometimes cut from a full sheet. When that larger format printer finally died I stopped because the smaller sheets handled by “standard” desktop printers doesn’t provide enough detail for me.
Canon’s website claims that printer can successfully feed up to 53#/200 gsm specialty paper, but 90#/210 gsm paper should fee with no problem.
My go to printer for decades was Epson because Epson invented inkjet printing and licenses the technology to all the printer manufacturers. My last two were larger format and handled 140#/300gsm wc papers without problems.
Skill is nothing more than talent practiced relentlessly.
