HP PCL Commands

Control Bit:

Determines whether the replacement data is encoded, and also the bit

 

boundaries of the command byte’s other two fields.

Offset Count:

The number of bytes the replacement data is offset from the current po-

 

sition in the seed row.

Replacement

The number of consecutive data bytes to be replaced.

Count:

 

Control Bit = 0

 

If the control bit is 0, the replacement data is uncompressed. Bits 0-2 contain the replacement count; bits 3-6 contain the offset count. The replacement count is the number of bytes to be replaced by the bytes following the command byte. The offset count is the location these replacement bytes will occupy relative to the current position in the seed row.

Like compression method 3, the current byte follows the last replacement byte or, at the begin- ning of a row, the left graphics margin. An offset of 0 is the current byte; an offset of 1 is the byte following the current byte.

If the offset count is 15, an offset count byte follows the command byte and is added to the command byte’s offset count. If the offset count byte is 0, the offset count is 15. If the offset count byte is 255, another offset count byte follows. The last offset count byte will be less than 255.

One more byte than that indicated by the replacement count will be replaced. That is, 000 = 1 and 111 = 8. For example, if the replacement count is 5, then 6 bytes are replaced.

If the replacement count is 7, a replacement count byte follows the command byte and any off- set count bytes. If the replacement count byte is 0, then 8 bytes are replaced. If the replace- ment count byte is 255, another replacement count byte follows. The last replacement count byte will be less than 255. All of the replacement count bytes are added to the replacement count in the command byte to get the total replacement byte count. One more than the total replacement byte count will be replaced.

Control Bit = 1

Operation is similar if the control bit is 1, except that the replacement data is run length encoded and the bit boundaries are different. Bits 5 and 6 contain the offset count; bits 0 - 4 contain the replacement count. As when the control bit is 0, optional offset bytes and replace- ment bytes may be added.

800, 700 specifications

The HP 700 is a noteworthy addition to HP's lineup of enterprise-level printers, designed specifically to meet the demands of small to medium-sized businesses. With an emphasis on speed, efficiency, and high-quality printing, the HP 700 series has carved a niche for itself in the competitive printing market.

One of the standout features of the HP 700 is its impressive print speed, which can reach up to 40 pages per minute. This rapid output ensures that businesses can keep up with their demanding workloads without sacrificing quality. The printer also offers a fast first-page-out time, allowing users to access their prints more quickly, which is especially beneficial in busy office environments.

Connectivity is another important aspect of the HP 700 series. The printer supports multiple connectivity options, including USB, Ethernet, and Wi-Fi, allowing for versatile integration into existing office networks. The inclusion of mobile printing capabilities enhances user experience; employees can print directly from their smartphones or tablets using HP's Mobile Print Solutions, making it easier to meet on-the-go printing needs.

The HP 700 is equipped with advanced security features, such as secure boot and firmware integrity checking, ensuring that sensitive documents remain protected against unauthorized access. Additionally, it includes features like PIN printing, which provides an extra layer of security by requiring users to enter a PIN before their documents are released for printing.

In terms of sustainability, the HP 700 is designed with energy efficiency in mind. It employs HP’s EcoSmart Black Toner technology, which not only delivers exceptional print quality but also contributes to lower energy consumption and reduced environmental impact. The printer is also compatible with HP's Cartridge Recycling program, allowing businesses to responsibly dispose of used toner cartridges.

The print resolution of the HP 700 series is another strong selling point, offering up to 1200 x 1200 dpi. This high resolution ensures that text and images come out crisp and clear, making it suitable for a wide range of applications, from professional documents to vibrant marketing materials.

In summary, the HP 700 series combines high-speed printing, versatile connectivity, robust security features, and energy efficiency, all while delivering exceptional print quality. These attributes make it an ideal choice for businesses looking to enhance their productivity and streamline their printing processes. Whether for day-to-day operations or specialized tasks, the HP 700 stands out as a reliable and efficient printing solution.
