A:AnswerYes, poor print quality are caused by 2 items. An issue with the machine or with the resolution provided to the printer.
Meaning if you send a print job and the resolution of the print is under 300dpi or below the result will be very poor. This is not a fault of the printer but of the source given to the printer.
Typically this should be no issue.
A:AnswerDepends on your software, while some check paper allow being placed in the paper tray several require you to use bypass trays on printers.
Thankfully this unit offers a bypass for such occasions.
A:AnswerYes, orient the checks face-down with the top of the page toward the front of the printer. Also, reverse the order of the checks - you still need checks 1-3 to be on top of the stack and check 4-6 to be on the second layer.
A:AnswerYes, it supports ARM based architectures. This unit supports Bonjour so you should have no issues attaching this to your home network and printing to it from nearly any device.
A:AnswerButch, you will need to send a file to the printer to print. If you are using a web browser like Google Chrome you would choose the print option from the menu and follow the prompts.
A:AnswerDoes not come with USB. I didn't need one. Wifi easy to set up. Toners are not ink. They are powder, so they never dry out. There is a slot for a printer USB cable, different than regular USB. Best buy can help you with that. I use it with hp laptop, chromebook, and phone. Should work for you.
