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. Copyright Hewlett-Packard Co. 1993 The information contained herein is subject to change without notice.
