cups prints only on reboots
When I print a file (test file has only 4 characters),
CUPS does not print.
However, whenever I reboot, CUPS will print all jobs,
clearing the CUPS job queue.
I can repeat this by creating new print jobs.
Before the reboot solution, about every 5 minutes,
CUPS gives errors like the following in /var/log/cups/error_log,
[Job 13] Unable to connect to printer; will retry in 30 seconds...: Connection timed out
[Job 18] Unable to connect to IPP host: Connection timed out
I configured the first printer (Job 13 above), an HP 4050, with lpd/lpr as
lpd://10.55.1.63/
and I configured the second printer (Job 18 above), an HP 4200, with ipp
as
ipp://10.55.1.69/
although many other settings also worked similarly.
I selected approprate print drivers thru the web interface http://localhost:631.
For example, for the HP 4050, I selected the driver (PPD) which said
HP Laserjet 4050 - CUPS+Gutenprint v5.0.0 (en)
Printing worked fine before our Microsoft administrators decided to
change all printers from standard internet IP's (199.129.207.*)
to reserved addresses (10.55.1.*).
I changed my computers IP address and the printers' IP addresses.
Indeed, I eventually removed all printing packages and reinstalled them.
It's possible our administrators also added filters,
but I get the following nmap results
PORT STATE SERVICE
21/tcp open ftp
23/tcp open telnet
80/tcp open http
280/tcp open http-mgmt
443/tcp open https
515/tcp open printer
631/tcp open ipp
9100/tcp open jetdirect
So the ports appear to be open,
and besides, Debian is printing when it reboots.
I run Debian version
4.0
with the following two packages installed
cupsys 1.2.7-4
cupsys-driver-gutenprint 5.0.0-3
and no *foomatic* packages.
Any ideas, so I needn't reboot to print?
