Almost every printer in my printerhood has avaliable to download driver pcl5 and pcl6 version... so what is the difference, and what driver I should use. There is an answer in hp docs.
and followed by this site:
Descriptions of the different drivers
HP to provide an efficient way to control printer features across many different printing devices created PCL. PCL was originally devised for the HP Dot Matrix and Inkjet series printers. The first printer HP LaserJet series printer was released in 1984 with the PCL 3 language.
PCL commands are compact escape sequence codes that are embedded in the print job before being sent to the printer. HP PCL formatters and fonts are designed to quickly translate application output into high-quality, device-specific, raster print images.
The PCL printer language is common to all HP printers and provided the commands needed to support color printing. There are six versions (1 thru 6) of PCL. Each subsequent version of the language includes commands not found in older versions as well as the older PCL commands. As a result, printers with more recent versions of PCL are backwards compatible with software that supports older versions of the language.
There are currently two versions of PCL that are used:
PCL 6 driver - PCL 6 uses a new modular architecture that can be easily modified for future HP printers and exhibits the following characteristics:
- Returns faster to the application after spooling data
- Prints complex graphics faster
- Data streams are more efficient for reduced network traffic
- Better WYSIWYG printing
- Improved print quality
- Truer document fidelity
- Complete backward compatibility
The PCL 6 language is very different from the earlier versions of PCL. One significant difference is the manner in which the commands are sent to the printer. Use the PCL 6 driver to take full advantage of the printer features. The PCL 6 driver is recommended unless backward compatibility with previous PCL drivers or older printers is necessary.
PCL 5 drivers - The PCL 5c driver provided the commands needed to support printing in color. Use the PCL 5e driver to preserve compatibility with documents created for older printers.
PS drivers - The PostScript (PS) was originally designed by Adobe® and is an interpretive programming language with powerful graphic capabilities. A program in this language communicates a description of a document to an output device (such as a printer). Generally, PostScript is recommended for use when the following are necessary:
- Matching font styles with other users in an organization
- When printing in a Macintosh environment
- When rendering graphics in a specific manner
- When printing with PostScript specific applications
