The Lexmark Forms and Bar Code Card is designed to accept electronic forms generated using Lexmark Forms Composer and saved in flash memory or hard disk in Lexmark printers using Lexmark Forms Manager. Requires either flash memory or a hard disk for electronic form storage in the MFP or printer. Merge and quickly print forms using only the variable ASCII text data transmitted over the network. This card supports PCL® and PostScript command access for more than 47 industry standard one-and two-dimensional bar codes. Use Lexmark Forms Manager to upload and manage forms, to update firmware and to change the mode. Only one of these cards may be used at any time: Forms and Bar Code, Card for IPDS or Card for PRESCRIBE. These cards are installed in the same single connector.
