f7deaa1a | 25 | * This driver filter currently supports Dymo, Intellitech, and Zebra |
26 | * label printers. | |
ef416fc2 | 27 | * |
28 | * The Dymo portion of the driver has been tested with the 300, 330, | |
f7deaa1a | 29 | * and 330 Turbo label printers; it may also work with other models. |
ef416fc2 | 30 | * The Dymo printers support printing at 136, 203, and 300 DPI. |
31 | * | |
f7deaa1a | 32 | * The Intellitech portion of the driver has been tested with the |
33 | * Intellibar 408, 412, and 808 and supports their PCL variant. | |
34 | * | |
35 | * The Zebra portion of the driver has been tested with the LP-2844, | |
36 | * LP-2844Z, QL-320, and QL-420 label printers; it may also work with | |
37 | * other models. The driver supports EPL line mode, EPL page mode, | |
79e1d494 | 38 | * ZPL, and CPCL as defined in Zebra's online developer documentation. |
