for more than a few years i have had the same problem on many printers on many machines bar none. the problem is that the first file of a print job gets an extra blank line at the top of the page, decreasing the number of lines on the first page of a set of print jobs by one. ie - if i say: $ cat file1 | lpf > lpt0 && cat file2 | lpf > lpt0 then only file1 will be prefixed with a blank line on it's first page, file2 will print as expected. this is the filter i use ... [please ditto any responses off list, thanks ...] #!/bin/sh # # lpf -- LP Filter. # prints PS (%!) * DOS (CRLF) * UNIX (LF) files. # printer should be set to DOS mode -> EOL=CR/LF. # 'read' destroys any ASCII 0 characters in 1st line. # 'echo' destroys leading whitespace space in 1st line. # PRN='-sDEVICE=okiibm -r240x144' # EPSON FX-100 # PRN='-sDEVICE=djet500 -r300' # HP DJ500 # PRN='-sDEVICE=cdj850 -r300' # HP DJ850 PRN='-sDEVICE=ljet2p -r333' # OKIDATA OL600e read -r line1 # snag 1st line into filter, don't treat \'s specially. if echo "$line1" | grep -q '^%!'; then gs -q $PRN -sOutputFile=- - && exit 0 elif echo "$line1" | grep -q '^M$'; then echo "$line1"; cat && echo -n && exit 0 else echo "$line1^M"; cat | sed s/$/^M/ && echo -n && exit 0 fi exit 2 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
