They may look like it, but all printers are not created equal. Laser printers are designed to function in different work environments like small/home offices, workgroups, or marketing departments. Selecting the wrong inkjet or laser printer can create bottlenecks in your workflow and cost you more than it needs to cost you.
It is advisable to talk to a professional if you are unsure of any of these questions. It may be the case that a MFP might be a better answer for your business than a traditional printer.
