20 ERROR
20 MEM OVERFLOW
Indicates a memory overflow; too much data is being sent to the printer and the printer has run out of memory. Pressing the CONTINUE key causes the printer to print only the information it has received.
If the error persists, it may be necessary to simplify the print job (i.e., fewer fonts and less graphics information) or have the customer purchase additiond memory.
21 ERROR
21 PRINT OVERRUN
Indicates that the information being sent to the printer is too complex for the printer (i.e., the formatting capabilities of the printer can not keep up with the formatting instructions being sent to it by the computer).
If the error persists, it maybe necessary to simplify the job (i.e., reduce the number of characters or different fonts used, reduce the number of pixels addressed or cursor repositions, or reduce addressing the same pixel location multiple times). With the HP 33449, this problem can also be resolved by adding at least one additional memory PCA and setting PAGEPROTECT=[LTR, LGL or A4].
22 ERROR
