4-24 PostScript Envelope Size Support The literal names in Table 4-9 are also supported as operators in userdict. These operators change the image size, but do not change the active paper source. Therefore, when these operators are used, part of the image may be clipped. When these literal names are used as operators, it is equivalent to executing the following PostScript emulation sequence. The following example uses a 3.875 x 7.5 envelope. >>setpagedevice Table 4-9: Envelope Sizes Supported  Supported ✘ Not Supported Envelope Sizes Printer Model C912 E321, E323 T630, T632, T634 Literal Name Size (mm) Size (inches) Size (points) 3.875x7.5envelope 98.4 x 190.5 3.875 x 7.5 [279 540]  3.875x8.875envelope 98.4 x 225.4 3.875 x 8.875 [279 639]  4.125x9.5envelope 104.8 x 241.3 4.125 x 9.5 [297 684]  110x220envelope 110 x 220 4.33 x 8.66 [312 624]  162x229envelope 162 x 229 6.38 x 9.01 [459 649]  176x250envelope otherenvelope1 176 x 250 Other 6.93 x 9.84 [499 708] [612 996]  ✘ otherenvelope Other [841 842] ✘✘ 1 For other envelopes, the page is formatted to 216 x 356 mm (8.5 x 14 in.) unless a size is specified by your software program.
