To obtain hardcopy laser output, one needs to run the FILES command to change the printer and/or plotter to the PS option. Note that some SPA plots such as MAP and SV write information such as contour levels to the assigned printer so you would want to have both PLOTTER and PRINTER assigned to PS. Also for the frequently used command sequence PLOT PRINT, one needs to have both the printer and plotter assigned. Of course, you can choose to send the printer output somewhere else such as your terminal or a disk file. All the FILES command does is redirect the graphics output to a disk file (named SPAPLOT.PS). To actually route this file to the laser printer, the user needs to issue the SPA COPY command which sends the file to the laser printer. Note thata this file will be overwritten the next time a plot or print request to the PS file is issued by the user. If you wish to save the Postscript file, you must rename it (for example with the UNIX "mv" function outside of the program before issuing another plot or print command. You can do this from another window if on an xterminal or console or exit the SPA program. Note that the COPY command will only route the graphical output from the last command line.
If there is more than one PostScript printer available on the system or network, the files can be routed specifically to a printer by inquiring the COPY function with a trailing question mark. The assignment of one laser printer to a given identification with the SPA program is provided in the startup script spa.csh.
The following sequence of commands will generate hardcopies at the laser printer assuming you have already assigned the printer and/or plotter to PS with the FILES command.
To plot and print header information of scan 7500 in S10 S10> 7500 PLO PRINT COPY or S10> 7500 PLO PRI S10> COPY
The following example will only generate a laser copy of scan 8000. S10> 7500 PLO PRI S10> 8000 PLO PRI S10> COPY
To obtain a listing of all the headers in S12, S10> PAGE S12 PRI COP
Note that the PAGE function at the beginning of the command line is highly recommended since it will start the listing at the top of the page rather than some arbitrary location.
To get a log of scans in S12 S10> S12 LOG S10> COP
