In 2015 we started to develop a "Flatbed, Desktop, Laser/Inkjet, Envelope Printer" to enhance the SMB and Home Office environment operation, where companies and people needed to mail out invoices, literature and invitation, that would have a hard time going through a 4 in 1 printer because of its limited ability to print on 200 pound stock. This US Patented (9,747,531) printer, satisfies the needs of all those groups that need on demand printing of the entire envelope (including the USPS STAMP), at the rate of 30 envelopes per minute from its 500 supply tray rear tray. The unit size is approximately 16" x 16" and weights about 20 pounds. It communicates via Bluetooth and/or connects via USB 2 or 3. The rear tray adjusts from 3" to 11+" to accept wide manila envelopes for brochure comers and other thick documents for mailing too.The Envelope Printer is available for Licensing, Manufacturing or Resellers. We will be available to help guide you on modifications and driver requirements.
