USING  THE UL COMMAND

     
     The User-Defined Line Type ( UL ) command allows you to
     define and store your own line types. The command does
     not itself select a line type, it only defines it. To
     select a line type use the Line Type ( LT ) command.
     For more information see the PCL 5 Printer Language
     Technical Reference Manual. The syntax for the UL
     command is as follows:
     
     UL index,[gap1,...gap20];
     
     or
     
     UL;

PARAMETERS:
     
     Index                         Identifies the number of
                                   the line type to be
                                   redefined.
     
     Gaps                          Specifies alternate pen
                                   down and pen up stretches
                                   in the line type pattern;
                                   if gaps are numbered
                                   starting with1, odd
                                   numbered gaps are pen up
                                   moves. The first gap is a
                                   pen down move.  A maximum
                                   of 20 gaps are allowed
                                   for each user-defined
                                   line type.
     

PROGRAM:
     
     LEGEND: Ec = [Ctrl] [P] [Esc] in DOS EDIT.
     
     
     EcE                           Resets the printer.
     
     Ec%0B                         Enters HP-GL/2 mode.
     
     IN;                           Initializes HP-GL/2 mode.
     
     SP1;                          Selects pen number 1,
                                   (black). Even though
                                   there is no physical pen,
                                   the SP command must be
                                   used to enable printing.
     
     PA4000,3000;                  Specifies absolute
                                   plotting and moves to
                                   (4000,3000).
     
     UL8,0,15,0,15,0,15,40,15;     Redefines the user-
                                   defined line type with an
                                   index number of 8;
                                   specifies the lines and
                                   spaces as follows, in
                                   percentages of the line
                                   distance: gap1 as a dot
                                   (0%), gap2 as a space
                                   (15%), gap3 as a dot
                                   (0%), gap4 as a space
                                   (15%), gap5 as a dot
                                   (0%), gap6 as a space
                                   (15%), gap7 as a line
                                   (40%), and gap8 as a
                                   space (15%).
     
     LT8,10;PU2000,2500;PD5000,2500;    Specifies line type
                                   number8 (just defined),
                                   with a pattern length of
                                   10% of the distance
                                   between P1 and P2, (in
                                   this case, the lower-left
                                   and upper-right corners
                                   of the PCL picture
                                   frame); lifts the pen and
                                   moves to (2000,2500);
                                   sets the pen down to draw
                                   a line to (5000,2500).
     
     Ec%0A                         Enters the PCL mode.
     
     EcE                           Sends a reset to end the
                                   job and eject the page.
