philpem@3 2 * P-Touch PT-2450DX printer driver
philpem@3 3 *
philpem@3 4 * P. Pemberton, 2009
philpem@3 5 *
philpem@3 6 * Specs:
philpem@3 7 * Printer head is 128 dots, 180dpi, for a total print area of ~18mm vertical
philpem@3 8 * by however long your TZ label tape is.
philpem@3 9 * Printhead size is (128/180)=0.711[.] inches, or 18.0622[.] mm
philpem@3 10 * Each dot is (18.062/128) = 0.1411[.] mm
philpem@3 11 * Printable area is (numdots * 0.1411) mm
philpem@3 12 *
philpem@3 13 * Tape width Margins Printable area
philpem@3 14 * mm dots mm dots mm dots
philpem@3 15 * 6mm 42 1.0mm 7 4mm 28
philpem@3 16 * 9mm 63 1.0mm 7 7mm 49
philpem@3 17 * 12mm 85 2.0mm 14 8mm 57
philpem@3 18 * 18mm 127 3.0mm 21 12mm 85
philpem@3 19 * 24mm 170 3.0mm 128 18mm 128 ***
philpem@3 20 *
philpem@3 21 * 24mm is slightly odd. Because the printhead is only 128 dots (18mm), the
philpem@3 22 * margins are enforced by this, and not the driver software. It is impossible
philpem@3 23 * to print right to the edge of a 24mm label in a PT-2450DX.
