Is this a problem in pdf2ps also?  When I ps2pdf'ed fossil.pdf and sent the
result to my HP4000, the printer hung.  Had to power cycle it.

When page calls gs to display a postscript file which uses \r as a line
terminator (not \n or \r\n), deadlock ensues.  Here's a correction (which
may also reduce the need for the '-P' option):

/sys/src/cmd/page/ps.c:429 a ps.c:430,434

No, it was specifically an interaction between page and gs.

I don't think pdf2ps has this problem.
Pdf2ps generates enormous files, since
they're just 300dpi (maybe 600dpi?) bitmaps.

They take a long time to print.

Better just to use fossil.ps.
