Image forming apparatus and computer program product

Abstract

An image forming apparatus selects a printing sheet of a size according to a printing condition when printing an image. The image forming apparatus includes a setting unit that sets a target printing sheet on a feed source that can feed recording sheets of a plurality of sizes.

1 . An image forming apparatus that selects a printing sheet of a size according to a printing condition when printing an image, the image forming apparatus comprising:
 a setting unit that sets a target printing sheet on a feed source that can feed recording sheets of a plurality of sizes.   
   
   
       2 . The image forming apparatus according to  claim 1 , further comprising a receiving unit that receives a size of the target recording sheet, wherein
 the setting unit sets the target recording sheet based on the size received by the receiving unit.   
   
   
       3 . The image forming apparatus according to  claim 2 , further comprising:
 a detecting unit that detects a width of a recording sheet that can be fed by the feed source; and   an obtaining unit that obtains a size of a recording sheet that can be fed by the feed source, based on the width detected by the detecting unit, wherein   when the obtaining unit obtains a plurality of sizes, the receiving unit receives the size of the target recording sheet from among the sizes obtained by the obtaining unit.   
   
   
       4 . The image forming apparatus according to  claim 3 , further comprising a storing unit that stores therein the width detected by the detecting unit, wherein
 when a width of a recording sheet newly detected by the detecting unit differs from the width stored in the storing unit, the setting unit sets recording sheets of all sizes obtained by the obtaining unit as the target recording sheet.   
   
   
       5 . The image forming apparatus according to  claim 3 , further comprising a storing unit that stores therein the width detected by the detecting unit and the size of the target recording sheet from among sizes obtained by the obtaining unit in association with each other, wherein
 when a width of a recording sheet newly detected by the detecting unit matches with the width stored in the storing unit, the setting unit sets a recording sheet of a size stored in association with the width newly detected by the detecting unit as the target recording sheet.   
   
   
       6 . The image forming apparatus according to  claim 1 , further comprising an receiving unit that receives an orientation of the target recording sheet, wherein
 the setting unit sets the target recording sheet based on the orientation received by the receiving unit.   
   
   
       7 . The image forming apparatus according to  claim 1 , further comprising:
 a receiving unit that receives a combination of width and orientation of all target recording sheets;   a storing unit that stores therein the combination of width and orientation of all target recording sheets; and   a detecting unit that detects a width of a recording sheet, wherein   the setting unit sets the target recording sheet based on a combination of width and orientation including the width detected by the detecting unit from among combinations of width and orientation of all target recording sheets stored in the storing unit.   
   
   
       8 . A computer program product comprising a computer-usable medium having computer-readable program codes embodied in the medium for selecting a printing sheet of a size according to a printing condition when printing an image, the program codes when executed causing a computer to execute:
 setting a target printing sheet on a feed source that can feed recording sheets of a plurality of sizes.   
   
   
       9 . The computer program product according to  claim 8 , wherein the program codes further causes the computer to execute receiving a size of the target recording sheet, wherein
 the setting includes setting the target recording sheet based on the size received at the receiving.   
   
   
       10 . The computer program product according to  claim 9 , wherein the program codes further causes the computer to execute:
 detecting a width of a recording sheet that can be fed by the feed source; and   obtaining a size of a recording sheet that can be fed by the feed source, based on the width detected at the detecting, wherein   when a plurality of sizes is obtained at the obtaining, the receiving includes receiving the size of the target recording sheet from among the sizes obtained at the obtaining.   
   
   
       11 . The computer program product according to  claim 10 , wherein the program codes further causes the computer to execute storing the width detected at the detecting, wherein
 when a width of a recording sheet newly detected at the detecting differs from the width stored at the storing, the setting includes setting recording sheets of all sizes obtained at the obtaining as the target recording sheet.   
   
   
       12 . The computer program product according to  claim 10 , wherein the program codes further causes the computer to execute storing the width detected at the detecting and the size of the target recording sheet from among sizes obtained at the obtaining in association with each other, wherein
 when a width of a recording sheet newly detected at the detecting matches with the width stored at the storing, the setting includes setting a recording sheet of a size stored in association with the width newly detected at the detecting as the target recording sheet.   
   
   
       13 . The computer program product according to  claim 8 , wherein the program codes further causes the computer to execute receiving an orientation of the target recording sheet, wherein
 the setting includes setting the target recording sheet based on the orientation received at the receiving.   
   
   
       14 . The computer program product according to  claim 8 , wherein the program codes further causes the computer to execute:
 receiving a combination of width and orientation of all target recording sheets;   storing the combination of width and orientation of all target recording sheets; and   detecting a width of a recording sheet, wherein   the setting includes setting the target recording sheet based on a combination of width and orientation including the width detected at the detecting from among combinations of width and orientation of all target recording sheets stored at the storing.
