Abstract
Conversion from a page description language (PDL) and conversion to a printer language is disclosed, as may be embodied in a device having two mechanisms. One mechanism is capable of converting a received file according to a printer-independent PDL to a first interim format. The other mechanism is capable of converting the received file, as has been converted to a second interim format, to a printer-specific printer language.
Claims36
A device comprising:
- a first mechanism capable of converting a received file according to a printer-independent page description language (PDL) into a first interim format;
- and,
- a second mechanism capable of converting the received file as converted to a second interim format into a printer-specific printer language.
A device comprising:
- an independently upgradeable printer-independent page description language (PDL) interpretation module;
- an independently upgradeable printer-specific printer language creation driver module;
- and,
- a module interface interfacing the printer-independent PDL interpretation module to the printer-specific printer language creation driver module.
A device comprising:
- first means for converting a received file according to a printer-independent page description language (PDL) to a first interim format;
- second means for converting the received file as converted to a second interim format to a printer-specific printer language;
- and,
- third means for interfacing the first means with the second means.
A method comprising:
- receiving a file according to a printer-independent page description language (PDL);
- converting the file from the printer-independent PDL to a first interim format;
- converting the file from a second interim format to a printer-specific printer language;
- and,
- sending the file as converted to the printer-specific printer language to a printer for printing.
A computer-readable medium having instructions stored thereon to upgrade a device for converting a file according to a printer-independent page description language (PDL) received from a client to a first interim format and for converting the file as converted to a second interim format to a printer-specific printer language for sending to a printer for printing so that the device is able to convert additional files according to one or more additional printer-independent PDL's to the first interim format.
A computer-readable medium having instructions stored thereon to upgrade a device for converting a file according to a printer-independent page description language (PDL) received from a client to a first interim format and for converting the file as converted to a second interim format to a printer-specific printer language for sending to a printer for printing so that the device is able to convert additional files as converted to the second interim format to one or more additional printer-specific printer languages corresponding and for sending to additional printers.
A computer-readable medium having instructions stored thereon for a computer program comprising:
- first means for converting a received file according to a printer-independent page description language (PDL) to a first interim format;
- second means for converting the received file as converted to a second interim format to a printer-specific printer language;
- and,
- third means for interfacing the first means with the second means.
