Monochrome printer with straight through paper path

[Deseverns]

I am just wanting to get a monochrome printer that has a straight through

printer path to be able

to print to very thick card stock. It is too thick

to make the L or U turn in most printers . A plus would be if it also has ink with iron oxide for decal

printing

Forget about new printers. New printers use polymer in toner to reduce heating temperature, saving energy and faster printing.

You need to look for an oldschool printer from HP, those have iron oxide and straight paper pass. Max paper weight is around 160 gsm for old school printers.
