The following error messages can appear when using the PFM Editor. A brief explanation of why the message appears is given after each message.
| Break character not in character set | |
| The break character must be between the first and last character in the character set, inclusive. | |
| Can't find filename, ignored | |
| The initialization file for a PCM file contained a reference to a PFM file that is not in the same directory, or that does not have the .PFM extension. | |
| Can't open filename, ignored | |
| The specified PFM file was in the current directory when the list box of available PFM files was created. However, when the attempt to write the PCM file was made, the PFM file could not be read. | |
| Can't write the PCM file | |
| An error occurred while writing to the PCM file, or to the associated initialization file. | |
| Changing the character range will invalidate the width table | |
| If you enter a width table and then change the first and last characters, the width table will no longer be valid. This will not occur if you have a specific font in mind when you create a PFM file. | |
| Couldn't save file filename | |
| The file specified could not be saved because of an error opening or writing the file, attempting to write over a read-only file, or running out of disk space. | |
| Default character not in character set | |
| The default character must be between the first and last character in the character set, inclusive. | |
| Driver information not specified | |
| You attempted to save a file that does not contain PCL driver information. | |
| Error creating the initialization file for filename | |
| The initialization file corresponding to the given file could not be opened. | |
| Error creating the PCM file filename | |
| The PCM file could not be opened because of an inappropriate filename (such as a nonexistent directory), a preexisting read-only file of the same name, or being out of disk space. | |
| filename contains the wrong driver information version | |
| This is a warning indicating that while the PFM file appears to be in the correct format, the driver-specific information contains a version number that this PFM Editor does not support. | |
| filename contains the wrong header version number | |
| This is a warning indicating that the PFM header has a version number that this PFM Editor does not recognize. | |
| filename does not contain driver information | |
| The PFM file does not contain a PCL driver structure. | |
| filename does not contain extended text metrics | |
| This is a warning that the PFM file being read into the PFM Editor does not contain extended text metrics. | |
| filename has been modified. Save before continuing? | |
| This message allows you to save a file or abort an operation before doing something that will abandon a modified PFM file, such as choosing the New, Open, or Exit commands. | |
| filename is not a valid file name | |
| The filename given is invalid because it contains illegal characters or syntax errors. | |
| filename is not a valid PFM file | |
| The specified file does not contain a PFM file, or the PFM file is either corrupted or from the wrong version. | |
| Proportional font requires a width table | |
| You attempted to save a PFM file that specifies a proportional font but does not contain a width table. | |
| Unrecognized device devicename | |
| The PFM contains a device name that the PFM Editor does not recognize. The only name recognized currently is “PCL/HP LaserJet.” | |
| Width table will need to be reentered | |
| This is warning indicating that changing your character range invalidates your width table. | |
| Write over original filename? | |
| A file with the same name as the filename you specified using the Save As command already exists. Choose Yes to write over the old file, or No to choose a new name. |
