HMhhh...
Well, first, what version of a2ps are you using? I think that at one time
the a2ps program stored its output in /tmp the same file.
Next, I tried this:
h110: {16} % a2ps /etc/printcap |lpr;
[/etc/printcap (plain): 1 page on 1 sheet]
[Total: 1 page on 1 sheet] sent to the standard output
h110: {17} % !!; !! ; !!;
a2ps /etc/printcap | lpr ; ; a2ps /etc/printcap | lpr ; ; a2ps /etc/printcap | lpr ; ;
[/etc/printcap (plain): 1 page on 1 sheet]
[Total: 1 page on 1 sheet] sent to the standard output
[/etc/printcap (plain): 1 page on 1 sheet]
[Total: 1 page on 1 sheet] sent to the standard output
[/etc/printcap (plain): 1 page on 1 sheet]
[Total: 1 page on 1 sheet] sent to the standard output
h110: {18} % lpq
Printer: lp@h110 (printing disabled)
Queue: 4 printable jobs
Server: no server active
Status: job 'root@h110+316' removed at 08:06:06.787
Filter_status: done at 07:57:39.731
Rank Owner/ID Class Job Files Size Time
1 papowell@h110+53 A 53 (STDIN) 14802 17:07:13
2 papowell@h110+58 A 58 (STDIN) 14802 17:07:20
3 papowell@h110+63 A 63 (STDIN) 14802 17:07:20
4 papowell@h110+68 A 68 (STDIN) 14802 17:07:20
done papowell@h110+677 A 677 h110 5538 07:57:27
h110: {19} %
And it appears to work fine. You can to 'lpc stop' to see if the jobs get there.
If only PART of the jobs get there, then... you might have the problem I just
mentioned.
Note that the a2ps ... | lpr should confirm this ... you pipe to LPR and it
makes a copy that is DEFINATELY unique.
