[. . . ] Context switching prevents unnecessary repetitive downloading and traffic congestion on networks. Normally, this memory client doesn't need to be changed unless you plan to download many different non-PostScript fonts such as PCL 5 fonts. Spool Buffers Also known as Host Input and K Mem for Spool, this memory client stores incoming data from all the interfaces until the emulation can process the print job. When enough memory is allocated to this client, the host becomes free more quickly, and the number of jobs that the printer can accept simultaneously is increased. You should consider the amount of data being sent simultaneously when allocating memory to the spool buffer. If available, a hard drive can supplement this client with additional memory needed for spooling. See the "Hard Disk Management" section later in this chapter. » Note: While increasing this client is beneficial in reducing network traffic, throughput speed is not necessarily increased. In addition, making this client too large could actually decrease throughput because of the overhead involved with managing a large spool. Additional Technical Information 5-19 Memory Disk Cache This memory client stores frequently used data in system memory instead of continually storing and retrieving it from a hard disk. If a hard disk is used and a lot of disk access is required, adding memory to the disk cache may increase the printer's performance. For example, if many fonts are stored on disk, faster access to these fonts is achieved by increasing the disk cache size. Conversely, if no hard disk is used, the disk cache should be set to its minimum value until a hard disk is installed. However, when one or more hard disks are installed, they are not available until the disk cache client is increased. The amount of memory needed for the disk cache client is dependent on the size of the disk, the number of disks, the number of subdirectories on each disk, and the amount of memory dedicated to caching. As long as the disk cache is enabled and there is enough memory in the disk cache, all disks are accessible. If insufficient memory is allocated to the disk cache, some disks may be seen while others are not. The disk cache is a high speed temporary buffer for data going to and from the hard disk. It can speed the printer in two ways: n n Information such as frequently referenced fonts and logos may still be in the cache and may not have to be pulled off a hard disk each time they're needed. Information being written to a hard disk can be held in the cache temporarily, if necessary, until a more convenient time to be written to disk. The recommended amount of memory for the disk cache client is as follows: n n n 20 KB internal usage 0. 5 KB per MB of disk storage total for all disks 100 KB of memory dedicated to caching 5-20 QMS 1060 Print System Reference Memory For example, the recommended disk cache client size for a single 120 MB hard disk would be 180 KB, and for two 120 MB hard disks it would be 240 KB. » Note: After you format a hard disk and the FORMAT COMPLETE message is displayed in the message window, the formatted disk may not be available to the system until the printer is turned off and then on again. MB Printer Mem This field shows the size of the physical RAM installed in the printer. If a hard diskis attached and Enable Disk Swap is set to On (Administration/Memory/Enable Disk Swap), it also shows the size of the "swap file. " MB Printer Mem This field shows the size of the physical RAM installed in the printer. If a hard disk is attached and Enable Disk Swap is set to On (Administration/Memory/Enable Disk Swap), it also shows the size of the "swap file. " System Memory Also known as System Use, this non-configurable client is the amount of RAM used to run the printer's operating system. The system memory subtracted from the total amount of RAM identifies the amount of RAM available for all the other memory clients. Hard Disk Management You can add one internal IDE drive and up to three external SCSI hard disks to your QMS 1060 Print System. [. . . ] A small circuit board designed to accommodate surface-mount memory chips. SIMMs use less board space and are more compact than more conventional memory-mounting hardware. SIO Simultaneous Interface Operation. The capability of printing to all three of the printer's concurrently active ports rather than being restricted to one. See also concurrent interfaces. Soft Fonts Fonts created or stored on disk. [. . . ]
