The remote printer name options used to invoke the different filters are as follows:

1Pb

Binary files (no filters)

1Pa

ASCII files (carriage returns at line

 

ends)

1pbf

Binary file with form feed at file end

1paf

ASCII file with form feed at file end

All other remote printer name options will be treated the same as lpb.

Note:

Some versions of lpr strip out all control characters and carriage return characters from a file before it is sent, making it unsuitable for bit-image files or font download files. In many cases the “4” option may be used on the lpr command line to prevent this happening (worth tying even if this option is not documented).

The following is an example of sending a text file, “txtfile,” via lpr with a form feed appended:

lpr -Plpaf txtfile
