This section is about label printing technology.

Label formats
There a few formats used by the various label printers.

• ascii - The ascii format is plain characters and new lines with no special abilities.
• epl - EPL is the original printer language used by Zebra label printers. If you want to learn how to write EPL, here is a link to the +ELTRON Programming Language (EPL) manual.
• zpl - ZPL is the newer printer language used by Zebra label printers. If you want to learn how to write ZPL, here is a link to the +Programming Guide ZPL ... manual.
• pcl - PCL is the format used by Hewlett-Packard LaserJet, OfficeJet, and DeskJet printers. They aren't really label printers, but the URL Label server can route PCL formatted print jobs to networked HP printers as a simple alternative to spoolers.

Format matching
The URL Label server associates a format with the destination printer.

• If the format of the incoming label matches the printer format, then the label data is sent to the printer unmodified.
• If the incoming label is ascii format, but the printer is not, then the ascii text is converted to the printer format and sent to the printer.
• If the incoming label format doesn't match the printer format, and it can't be converted, then the print job is incompatible and rejected.
