Available PostScript Memory
This option specifies the amount of available PS memory. The available PS memory is a subset of the
printer's total physical memory. It is usually best to use the default setting, which is determined by your
printer manufacturer.
Output Protocol
This option specifies the protocol that the HP Color LaserJet 2605 uses for print jobs. The following
options are available.
●
ASCII . (default) When you click ASCII , data is sent in ASCII format (7-bit), which might take longer
to print but can be sent through any I/O channel, such as a USB or network port.
●
TBCP . When you click TBCP (Tagged Binary Communications Protocol), all data except special
control characters is sent in binary (8-bit) format. The binary formats can be sent over USB or serial
communications ports at a faster rate than by sending data in ASCII format.
●
Binary . When you click Binary , all data except special control characters is sent in binary (8-bit)
format. The binary formats can be sent over USB communications ports at a faster rate than by
sending data in ASCII format.
