.png and .eps files generated by matplotlib won't print on RHEL 5

Question

I'm using matplotlib.pyplot to plot some data, and after running plt.show() I save the image as either a PNG image or encapsulated postscript.

When I open these saved files with evince and try to print them, a job is sent to the printer but nothing is printed. The plots display on the screen with no problems.

Is there something specific I need to do in matplotlib to generate printable PNGs and EPSes? Is this a bug in matplotlib?

Answer 1

Here are a few steps to start debugging this situation:

• (1) Stop your cupsd (CUPS daemon).
• (2) Change in cupsd.conf: LogLevel debug (instead of LogLevel info.
• (3) Delete your log file /var/log/cups/error_log.
• (4) Start your cupsd again.
• (5) Print your problem EPS.
• (6) Check your cupsd.conf logfile for errors.

Report the errors here. (Errors may be recognized by the prefixed E on each line.) Also, what is the result of the Auto-typing step?

Alternatively: can you provide a link to a sample of your problem EPS?
