Printer type for direct printing
Printer type SW 1-7 SW 1-8
EPSON 24-pin color printer (80 col.) OFF OFF
HP PaintJet color printer (parallel) ON OFF

Direct printing is available only when the GT-6000 is directly
connected to a printer through the parallel interface. This function
has no relation to ordinary software controls. See the GT-6000
user’s guide for further details.

- In dots the maximum main scan value at the maximum resolution 100 zoom 74
- In dots the maximum sub scan value at the maximum resolution 100 zoom 74
- In dpi the maximum scannable area available 74

- This section explains how to use the esc r esc h and esc a commands to print a trimmed image on your printer 80
- Based on the size of the image you plan to print and on the resolution of the printer use the following formulas to determine the final scanning settings 81
- Determining the setting values for printing 81
- Main scan zoom 81
- Note on scanners that can respond to printers and other various output devices you can set the 81

- Problem although you have attached a new scanner capable of a higher resolution you cannot achieve that resolution when scanning 90
- Problem when connecting a different scanner model in your scsi daisy chain an error message such as the following appears the epson scanner is not connected 90
- Problem after connecting a scanner with a higher function level than the previous scanner the new scanner does not operate properly 91
- Problem the speed of image data transfer remains the same whether you use a scsi or bi directional parallel interface 91
- Problem after using a scanner option automatic document feeder or transparency unit a different program attempts scanning although the second program tries to scan without using the option the option remains operational 92
- Problem the scanner scans properly when you use a bi directional parallel interface but when you switch to scsi the scanner no longer operates properly 92
- Problem when connecting a different scanner model a time out occurs on your computer and you can no longer scan 93
- Problem when writing data from a gt 6000 or gt 4000 to a magneto optical disk an interface error occurs on the scanner 93

- In the color scanning mode the data format setting defines tones for each of the three primary colors green red and blue 117
- Note even when the specified values exceed the capabilities of the computer display or printer data is sent according to the specified format and quantity before scanning you should consider how the image data can be stored or processed 117
- Specifying the data format determines the amount of image data in each data block 117
- The data format selected by this command determines the effective halftoning mode selectable with the esc b command 117
- With multilevel data settings more than 3 bits per pixel per color the halftoning modes are not effective 117
