Vpr causes the named files to be queued for printing or typeset simulation on one of the available raster printer/plotters. If no files are named, the standard input is read. By default the input is assumed to be line printer-like text. For very wide plotters, the input is run through the filter /usr/lib/sidebyside giving it an argument of -w106 which arranges it four pages adjacent with 90 column lines (the rest is for the left margin). Since there are 8 lines per inch in the default printer font, vpr thus produces 86 lines per page (the top and bottom lines are left blank).

The following options are available:

15 -l Print the input in a more literal manner. Page breaks are not inserted, and most control characters (except format effectors: \\n, \\f, etc.) are printed (many control characters print special graphics not in the ASCII character set.) Tab and underline processing is still done. If this option is not given, control characters which are not format effectors are ignored, and page breaks are inserted after an appropriate number of lines have been printed on a page.

15 -W Queues files for printing on a wide output device, if available. Normally, files are queued for printing on a narrow output device.

15 -1234 Specifies a font to be mounted on font position i. The daemon will construct a .railmag file referencing /usr/lib/vfont/name.size.

15 -m Report by mail (1) when printing is complete.

-w (Applicable only to wide output devices.) Do not run the input through sidebyside. Such processing has been done already, or full (440 character) printer width is desired.

-wwidth Use width width rather than 90 for sidebyside.

-v Use the filter /usr/lib/vrast to convert the vectors to raster. The named files must be a parameter and vector file (in that order) created by plot (3X) routines.

-t Use the filter /usr/lib/vcat to typeset the input on the printer/plotter. The input must have been generated by troff (1) run with the -t option. This is not normally run directly to wide output devices, since it is wasteful to run only one page across. The program vtroff (1) is normally used and arranges, using vsort for printing to occur four pages across, conserving paper.

Vprm removes entries from the raster device queues. The id, filename or owner should be that reported by vpq. All appropriate files will be removed. Both queues are always searched. The id of each file removed from the queue will be printed.

Vpq prints the queues. Each entry in the queue is printed showing the owner of the queue entry, an identification number, the size of the entry in characters, and the file which is to be printed. The id is useful for removing a specific entry from the printer queue using vprm

Vprint is a shell script which pr's a copy of each named file on one of the electrostatic printer/plotters. The files are normally printed on a narrow device; -W option causes them to be printed on a wide device.

troff(1), vfont(5), vp(4), pti(1), vtroff(1), plot(3X) The 1's (one's) and l's (lower-case el's) in a Benson-Varian's standard character set look very similar; caution is advised.

A versatec's hardware character set is rather ugly. Vprint should use one of the constant width fonts to produce prettier listings.
