VUTRAX Technical SupportVUTRAX SOFTWARE ADVICE NOTICE 43a - 17 Oct 1988 Revised for VUTRAX 11.7 and 12.0 - 19 Feb 1998 HP LaserJet Printer - Plotting outside the Normal Border The natural borders for the HP LaserJet extend to within about 5mm of each paper edge, but the top and bottom default starting and ending rows are about 20mm from the paper edge. This note describes how to alter the HPLASER?.BXY plot control file to use the entire printable area. Warning: Attempting to print to the very edge of the top and bottom edges will cause plotted material to enter the plotter mechanisms 'unprintable region' and be lost. Because the 'unprintable region' varies we can not provide definitive values in this note, nor standardise on a scheme for general issue. Use the SEE editor or similar plain text editor to edit the supplied file HPLASERP.BXY (parallel interface) or HPLASERC.BXY (serial interface) into one of a different name (e.g. HPWHOLE.BXY). The hieroglyphics are required by the plotter - be sure to get them exactly right - PLOT can not check, and just passes what you type to the plotter Find the line (where $Ic>1 is unique in the file):- $Ic>1;$K27;&l$V1,c;X$R$U$N Copies Remove the 'R$U' and replace it with 'J'. Follow with the new additional lines, noting that each &l uses lower case L, NOT numeral 1:- $K27;&l48D$K27;<ttE$ $K27;&lbbbF$K27;&l6D;$R$U$ This sequence sets 48 l.p.i., sets the top border and length using units of 1/48", and reverts to 6 l.p.i. Two of the fields must be user selected:- ttt is the distance as ttt/48" from the theoretical top of sheet that plotting starts. Initially try value '3' bbb is the length of the plottable region bbb/48" from the specified top - i.e. it determines the bottom. For A4 paper initially try value '555' To use the additional area, specify the VE>height< option in the command line, menu option [Printable Height]. If you would prefer the larger size to default (probably once you have your setup established) find the line $Ie<=0;$Se=11.0;$J$N Set default height and change the 11.0 to your prefered value, obtained using the formula bbb/48 (11.5625 for the suggested start value 555). Prepare an overlength plot (possibly size calibrated) and plot it at 1:1, headings suppressed. Inspect the output (particularly looking for loss at the top) and adjust the parameters to suit your particular plotter mechanism. Avoid the auto-size adjust options (A & AA) until the true limits are established. |
