NAME

collpr − simulate model 37 tty on the line printer

SYNOPSIS

collpr [ − ] [ file ...  ]

DESCRIPTION

Collpr simulates a model 37 teletype for doing nroff output on the line printer.  Pages are buffered and reverse line-feed and half-line feed sequences are interpreted.  Half-line up material is overstruck on the previous line, half-line down material is struck on the current line. In general, though, overstruck characters are lost, except for underlining. Combinations of ‘−’ or ‘_’ and ‘|’ are turned into ‘+’, i.e. at the corner of boxes. The optional argument − causes the output to be sent to the standard output.  By default it is sent to an instance of the line printer daemon, lpr (I).  A typical usage of collpr would be tbl exum2.n | nroff −ms | collpr to nroff the document in the file exum2.n and send it to the line printer with a approximation of the tables printing there.

BUGS

Output can’t be backed up more than 102 lines.  Overstriking is lost. Lines are trimmed to 132 characters. Superscripts of the first output line are lost. If more than one file is specified, the program does not pad the files out with a form feed as lpr would do.  Should move subscripts down a line rather than printing them on the same line as the normal material.
