Precautions for RICOH-SCRIPT2
Differences between RICOH-SCRIPT2 and “PostScript Language
Reference Manual, Second Edition”
The differences between RICOH-SCRIPT2 and PostScript Level 2 as defined in
the “PostScript Language Reference Manual, Second Edition” by Adobe Sys-
tems Incorporated are described below.
• RICOH-SCRIPT2 does not support the “user path cache” function, therefore
the print processing speed may be reduced when this function is called by
any PostScript program. This function originated in Display PostScript, and
it is not used by most printer drivers.
• RICOH-SCRIPT2 does not support “automatic garbage collection”. Instead, a
similar routine is implemented by the printer drivers with the “save/restore”
operators. Not having this function does not create any problems.
Other Precautions
• Because of the differences in image, graphics, and clipping rules, the printing
results produced by any single draw operator might be out of place by one
dot.
• The free memory space used for downloading fonts may not be sufficient. A
VM error might occur when downloading fonts with insufficient VM memo-
ry. In this case, the print job may be canceled. However, this printer will re-
start RICOH-SCRIPT2 automatically.
• Lasertalk version 1.3 is not supported.
• Built-in font metric data may be different from the PostScript fonts.
• Type 1 fonts conform to the Adobe Type 1 font format (1.1) standard. How-
ever, some Type 1 fonts with outline transposition (self-interference) may not
print correctly.
• When printing text without using “font hint data” downloaded from the ap-
plication, enlarged or reduced fonts may print incorrectly.
• When using the PostScript printer driver with Windows applications, the
printed result might not match the preview on the computer screen.
