Causes of the HP Printer PCL XL Error Kernel Unsupported Protocol
The following are the causes of the HP printer PCL XL error kernel unsupported protocol:
1. The Printer and Computer have a Mismatched Font
If a computer’s font cannot be parsed (matched) by your HP printer, then it will lead to the error being discussed.
2. Conflicting Applications are Causing Interference
If the printer’s print data stream is experiencing interference from another application such as your computer’s antivirus, it might cause certain characters to become difficult for your printer to translate. Such interference can cause the error.
3. Corrupt or Outdated Printer Driver
When your printer driver becomes corrupted or outdated, it will become incompatible with some printing modules. When a print job is sent in such a case, your printer might not render it properly thereby leading to the error under discussion.
4. User Profile is Corrupt
A corrupt user profile can cause the print job’s characters to become non-parsable.
