Cause of error code 20 INSUFFICIENT MEMORY

The printer received more data than can fit in available memory.

Solution for error code 20 INSUFFICIENT MEMORY

You may be trying to print a document that is too complex for the printer's capacity (too many macros, soft fonts, or graphics). Pressing GO may print the transferred data, but data may be missing or skewed.  If the file size of the print job exceeds printer's onboard memory capacity, try adding more memory. Sometimes mismatched software drivers over-inflate the size of a document and cause these errors; you may want to download/install a different driver. If all else fails, simplify the print job and print manageable segments at a time.
