After I upgraded to 3.2.4, the command that allows me to print directly to
printer no longer works. I could still print the plot to file, but it is
inconvenient & I couldn't save the file in the format that I wanted.
When I reverted back to 3.0.3, the said command worked again. I suspected
that the changes that have been made in
/usr/share/octave/3.2.4/m/plot/print.m might be the culprit. However, I
couldn't interpret any new addition or removal in that particular file since
it is too advanced for me; therefore, I hope any octave expert here could
enlighten me.
I also posted the mentioned problem to bug reports.
BTW, I'm running Linux. I don't suspect anything with my operating system
since the older version of Octave works fine in term of print job.
Thanks,

Please check to see if the job shows up in your print que. Type ....
clf
surf (peaks)
print
system ("lpq")
pause (10)
system ("lpq")
Does the job show the first time the que is displayed?
Does the job remain in listed in the que when the que is displayed the second time?
Ben
Thank you for the quick response.
The plot did show up, but then it gave me this following message both times when I typed system ("lpq").
HP_LaserJet_1020_USB_1 is ready
no entries
ans = 0
Does it mean the print job was never sent to the printer?
I'm not sure.
try the following ...
clf
surf (peaks)
print -dpsc test.ps
[status, output] = system ("lpr -l test.ps ; lpq")
If the que is empty, then I suggest you verify you can print from the command line.
I have limited experience with "lpr", but if you have questions please ask. If I can't help, someone else will be able to.
Ben
p.s. Pls reply at the bottom to make it easier for those arriving late to follow along. Thanks.
Here is what the output produced:
status = 0
output = HP_LaserJet_1020_USB_1 is ready and printing
Rank Owner Job File(s)
Total Size
active murlox 1079 test.ps
294912 bytes
The printer was on and it didn't print anything, so I don't know
what to do. Maybe both octave & lpr work, but they failed to
communicate with each other.
Thanks,
Al
