morovia pcl barcodes & more was conceived to provide a soft font solution that allows customers whose applications are based on the original hp pcl barcodes & more cartridge to upgrade their printers without interruption of the operation. hp used to sell a cartridge font-based barcode solution called bar codes & more™. the cartridge contains several pcl bitmap fonts to print barcodes such as code 3 of 9, upc and us zip barcode. new printer models no longer carry this package. this leaves many customers in dilemma: they have to either rewrite their applications at the time of a printer upgrade, or keep the old slow printer. considering the demands for a compatible solution so that the original programs can continue to function without interruption or invest heavy cost rewriting the code, morovia has developed a soft-font based solution. the fonts have the identical characteristics as the hp package, yet they are independently developed by morovia and morovia holds the intellectual property rights to the product. after the soft fonts are downloaded and made permanent in your printer, your application continues to operate as if the original hp cartridge is still in place. although early printers have the pcl interpreter built-in the printer hardware, nowadays some inexpensive models place the pcl interpretor on the host side (often called host-based pcl interpretor). you can not send pcl commands to these printers directly via lpr command.
