     1.5 + * P-Touch PT-2450DX printer driver
     1.6 + *
     1.7 + * P. Pemberton, 2009
     1.8 + *
     1.9 + * Specs:
    1.10 + *   Printer head is 128 dots, 180dpi, for a total print area of ~18mm vertical
    1.11 + *   by however long your TZ label tape is.
    1.12 + *   Printhead size is (128/180)=0.711[.] inches, or 18.0622[.] mm
    1.13 + *   Each dot is (18.062/128) = 0.1411[.] mm
    1.14 + *   Printable area is (numdots * 0.1411) mm
    1.15 + *

    1.20 + *     12mm   85    2.0mm    14   8mm   57
    1.21 + *     18mm  127    3.0mm    21  12mm   85
    1.22 + *     24mm  170    3.0mm   128  18mm  128 ***
    1.23 + *
    1.24 + *   24mm is slightly odd. Because the printhead is only 128 dots (18mm), the
    1.25 + *   margins are enforced by this, and not the driver software. It is impossible
    1.26 + *   to print right to the edge of a 24mm label in a PT-2450DX.
