HP PCL Commands

The following data is compressed using method 3. Italicized bytes are those needing replace- ment, i.e., bytes different from the seed row. Graphics data is binary.

Esc * r 1 A

Start Raster initializes the seed row to all zeros.

Row 1 - Esc * b 3 m 2 W (00000001 )( 11111111 )

3m selects method 3, and 2W indicates that 2 bytes of data will follow. The upper three bits of the command byte are zero, indicating that one byte will be replaced. The lower five bits con- tain a relative offset of 1, indicating that the replacement occurs one byte in from the current position. The replacement byte follows and contains 11111111.

Row 2 - Esc * b 2 W (00000010)(11110000)

The first three bits of the command bye are 0 indicating one byte will be replaced. The lower five bits contain a relative offset of 2; so the replacement will occur 2 bytes from the current position. The replacement byte 11110000 follows.

Row 3 - Esc * b 5 W (00000000)(00001111)(00100010)(10101010)(1010 1010)

Three bytes are replaced using two commands. The first three bits of the first command byte are zero, indicating a single byte replacement, and the next five bits are zero, indicating a rela- tive offset of zero. The replacement byte 00001111 follows.

The first three bits of the second command byte are 001, indicating the replacement of two bytes; and the lower five bits contain a relative offset of two. The two replacement bytes (10101010)(10101010) follow the command byte.

Method 9 - Compressed Replacement Delta Row Encoding

Like Method 3, this method replaces only bytes in the current row that differ from the preced- ing (seed) row. Unlike Method 3, the replacement (delta) bytes may be encoded.

A delta compression string consists of a command byte, optional offset bytes, optional replacement count bytes, and the replacement data.

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.
