I have a client has a Brother HL-2270DW that is used primarily for printing checks from QuickBooks (along with some typical printing). Having lots of problems with the Brother because the manual feed only takes 1 page and is unreliable, and the paper tray orientation isn't compatible with check-printing. Paper goes in it face down and bottom-first, so you have to manually re-sort a stack of checks to have them print in the right order. This is a deal-breaker.
We need an inexpensive (around $100) laser printer that feeds checks from the tray correctly for QuickBooks, or that has a very good manual feed that can handle about 20 checks at a time.
