LPrint implements printing for a variety of common label and receipt printers connected via network or USB. Features include:
- A single executable handles spooling, status, and server functionality.
- Multiple printer support.
- Each printer implements an IPP Everywhere™ print service and is compatible with the driverless printing support in Android™, Chrome OS™, iOS®, Linux®, macOS®, and Windows® 10/11 clients.
- Each printer can support options such as label modes, tear-off offsets, media tracking, media top offset, print darkness, resolution, roll selection, and speed.
- Each printer can directly print "raw", Apple/PWG Raster, and/or PNG files.
- Each printer automatically recovers from out-of-media, power loss, and disconnected/bad cable issues.
For more information, see the file "DOCUMENTATION.md", the man pages in the "man" directory, and/or the LPrint project page at https://www.msweet.org/lprint.
Note: Please use the Github issue tracker to report issues or request features/improvements in LPrint:
LPrint depends on:
- A POSIX-compliant "make" program (both GNU and BSD make are known to work),
- A C99 compiler (both Clang and GCC are known to work),
- PAPPL 1.1 or later.
- CUPS 2.2 or later (for libcups).
The following printers are currently supported:
- DYMO LabelWriter printers
- Zebra/Eltron EPL2 printers
- Zebra ZPL printers
Others will be added as time and access to printers permits.
Through PAPPL, LPrint implements PWG 5100.14-2013: IPP Everywhere™ and the IPP Label Printing Extensions v1.0 for each printer, and has a partial implementation of PWG 5100.22-2019: IPP System Service v1.0 for managing the print queues and default printer.
