Homelite HL-1070 Entity error codes, Free space command, ESC*s1M 27421154877 1Bh2Ah73h31h4Dh

10/10/03

Status location type 1 (selected at present) is an incorrect location for unbound font symbol sets and returns an error.

Example responses in this section for "SYMBOLSETS=" do not indicate the complete list of symbol sets which are available internally, but only a partial list . The internal symbol sets depend on the printer and might differ according to the printer.

8.5.15. Entity error codes

When an out-of-range value exists in the command value fields, or when the entity is not supported or does not exist, or the request is inadequate, the printer replies with one of four likely errors as follows:

Invalid Entity

Invalid Location

None

Internal Error

ERROR=INVALID ENTITY

When the identified entity type is not in the range or not supported, it returns an invalid entity error.

PCL

INFO ENTITY

ERROR=INVALID ENTITY

ERROR=INVALID LOCATION

When the entity type is correct, but the location ( the type, the unit, or the combination) is not, or when the identified device is not installed, it returns an invalid location error.

PCL

INFO FONTS

ERROR=INVALID LOCATION

ERROR=NONE

When the entity type and location are correct, but there are not any entities of the identified type in the location, or when the type is not correct for the identified entity, it generates the NONE error response.

PCL

INFO SYMBOLSETS

ERROR=NONE

ERROR=INTERNAL ERROR

The status response for some requirements could be quite big. When status replies are requested, it returns an internal error if the printer runs out of memory as follows:

PCL

INFO SYMBOL SETS

ERROR=INTERNAL ERROR

8.5.16. Free space command

ESC*s1M (27)(42)(115)(48)(77) <1Bh><2Ah><73h><31h><4Dh>

The amount of memory which is free for use is returned by this command. Two values are returned: the total amount of free memory and the largest block of free memory.

When you send a value other than 1, an error ( "ERROR = INVALID UNIT" )is returned.

The Free Space command is sent to check the free memory space and you can acknowledge whether the printer has enough memory for a job or not before you execute your job. Also you can check the amount of memory which an entity or any other data has already used.

Free memory space will always be changing during different printing conditions.

For example, when the printer receives print data, it is stored in the printer memory and so the free space in the printer memory becomes smaller. After the data is printed, the printer memory becomes empty, so the free space becomes larger again.

Certain action is needed when you decide there is not enough memory to hold the data to be downloaded.
