I have a postscript printer installed and working with lpd but if
the postscript files I print are over say 1.5MB lpr complains that
"copy file is too large". The job prints but it's not complete.
Reading the manual page for lpr I indeed find a warning that lpr may
truncate jobs which are "too big". Fair enough but really, if I need
to print more than ten pages of postscript I often can't do it. Since
it's postscript it is very hard to split it up into smaller chunks.
It seems to me that on some systems (SCO comes to mind) that large jobs
get chunked up into manageable size peices. Is there something I'm
missing here? Is this not a common problem?
Code fragment from lpr.c:
while ((i = read(f, buf, BUFSIZ)) > 0) {
if (write(fd, buf, i) != i) {
printf("%s: %s: temp file write error\n", name, n);
break;
}
nc += i;
if (nc >= BUFSIZ) {
nc -= BUFSIZ;
nr++;
if (MX > 0 && nr > MX) {
printf("%s: %s: copy file is too large\n", name,
n);
break;
}
}
}
