I have been a notary signing agent for a year. I’ve done nearly 200 signings. I have a Brother MFC-L3770CDW, a Brother HL-L2300D (mobile/portable), and a Lexmark MX421ade w 2 trays. I thought the Lexmark would print mixed sizes w/o difficulty. I have yet to be successful. I have spent hour w Lexmark tech support, Adobe support, and Apple support. Can anyone help?
Additionally, I keep getting a debug error code on the Lexmark 900.001( I think), I know the code means a communication problem between printer and computer. Lexmark techs have not gotten rid of the problem just told me I hadn’t kept the print driver software up-to-date. ( after the last so called fix, it did it again that evening when tech support was closed.)
Can anyone help w these issues?
