The file in gLabels is very simple, and has only an image in it. However, I have discovered that , the type of image does seem to affect the size of the spool for the print job, as does the print mode (grey/RGB).
Printing greyscale always works normally (spool file less than 200KB). However, if I print RGP, then the type of image in the gLabels file will affect the size of the spool for the print job:
- GIF image: spool file is 850MB
- PNG image with alpha channel: spool file is 850MB
- PNG image with no alpha channel: spool file is <200KB
- JPG image: spool file is <200KB
Also, increasing the print resolution will increase the size of the spool file for the print job. At 300dpi, the spool file is 850MB. At 600dpi, the spool file fills all available space (8GB!).
What can I do to help you diagnose the problem?
