sii_printpbm allows you to print PBM files to the Seiko Instruments thermal label printer (SII SLP1100) from a UNIX box. This printer is also sold as the EZ30 Smart Label Printer. You can use ghostscript to render a postscript file to a PBM file and send it to the sii_printpbm installed as a print filter to lpd. This was first seen in action at the Atlanta Linux Showcase in 1998.
The program is to be used in conjunction with a print
filter that converts an image into a PBM file before
sending it to the printer.
